Distribution of chondroitin sulfate in cartilage proteoglycans under associative conditions. (1/440)

Proteoglycan aggregates and proteoglycan subunits were extracted from bovine articular cartilage with guanidine-HC1 folowed by fractionation by equilibrium centrifugation in cesium chloride density gradients. The distribution of chondroitin sulfates (CS) in the cartilage proteoglycans was studied at the disaccharide level by digestion with chondroitinases. In the proteoglycan aggregate fraction, it was observed that the proportion of 4-sulfated disaccharide units to total CS increased from the bottom to the top fractions, whereas that of 6-sulfated disaccharide units was in the reverse order. Thus, the ratio of 4-sulfated disaccharide units to 6-sulfated disaccharide units increased significantly with decreasing density. The proportion of non-sulfated disaccharide units to total CS tended to increase with increasing density. These data indicate a polydisperse distribution of CS chains, under the conditions used here, in proteoglycan aggregates from bovine articular cartilage.  (+info)

Complexes of aliphatic sulfates and human-serum albumin studied by 13C nuclear-magnetic-resonance spectroscopy. (2/440)

The interaction of human serum albumin and various long-chain sulfates has been studied. Binding of sodium octylsulfate to albumin increases in the concentration range studied as measured by equilibrium dialysis. In contrast, binding of the sodium salts of decylsulfate and dodecylsulfate is constant at a concentration of free ligand higher than 50 mM and 12 mM corresponding to binding of 110 and 83 sulfate molecules per albumin molecule, respectively. Viscosity measurements indicate that binding of decylsulfate and dodecylsulfate is associated with unfolding of the albumin molecule. In contrast, binding of octylsulfate does not cause gross conformation changes of albumin. However, the chemical shifts of bound octylsulfate obtained by natural abundance 13C nuclear magnetic resonance spectroscopy show significant changes at 80 mM and 150 mM free ligand. The spin-spin and spin-lattice relaxation times also show changes in the association between octylsulfate and albumin at 80 mM free sulfate. These observations indicate alterations in the binding properties at 10--11 and 20--21 bound ligand molecules, respectively. The relaxation times are considerably increased by binding to albumin, indicating less motional freedom of the molecules in the bound state. At high levels of sulfate binding the relaxation times of the terminal methyl group approach that of free ligand. The chemical shifts of all the bound carbon atoms studied, except the CH2 group nearest to the sulfate group (C1), are comparable to those observed in the micellar state indicating binding in a non-polar environment. However, the relaxation times indicate that the motional freedom of sulfates bound to albumin is much more restricted than in micelles. The shift of C1 indicates that this part of the ligand is situated in a polar environment. The following model for binding of high concentrations of aliphatic detergents is proposed. The sulfate group and the CH2 group nearest to it is situated in a polar medium caused by interaction between the sulfate group and a positive amino acid residue on albumin. The other CH2 groups interact with hydrophobic amino acid residues on albumin. The CH3 group does not interact with the albumin molecule but associates with other methyl groups of sulfates bound in the vicinity forming a hydrophobic medium.  (+info)

Effect of cholesterol sulfate and sodium dodecyl sulfate on lecithin-cholesterol acyltransferase in human plasma. (3/440)

The effects of cholesterol sulfate and sodium dodecyl sulfate (SDS) on the esterification of cholesterol in sonicated dispersions of lecithin-cholesterol mixtures by lecithin-cholesterol acyltransferase [EC 2.3.1.43] (LCAT) in human plasma were studied in vitro. The acyltransferase activity was inhibited at concentrations of cholesterol sulfate higher than 1 X 10(-4) M. This inhibition was not eliminated by the addition of bovine serum albumin or CaC12. On the contrary, the acyltransferase activity was stimulated at concentrations of SDS ranging from 1 X 10(-5) M to 1 X 10(-3) M, and maximum stimulation was obtained at 5 X 10(-4) M. The maximum stimulation disappeared on the addition of bovine serum albumin (30 mg per ml of incubation medium), 1 X 10(-3) M CaC12 or 1 X 10(-4) M cholesterol sulfate. On the other hand, the extent of inhibition of the acyltransferase by cholesterol sulfate was not affected by the amount of lecithin in the dispersion added as a substrate, but the maximum stimulation (5 X 10(-4) M SDS) of the acyltransferase was interfered with when a large amount of lecithin was present in the dispersion. In addition, the amount of SDS required for maximum cholesterol esterification was not affected by the amount of lecithin present in the dispersion. These results suggest that the action of cholesterol sulfate on the acyltransferase is different from that of SDS.  (+info)

Suspected nasopharyngeal carcinoma in three workers with long-term exposure to sulphuric acid vapour. (4/440)

Sulphuric acid vapour has been suspected of being an industrial carcinogen. In this study, a cluster is presented of three patients with nasopharyngeal carcinoma (NPC) who worked in the same building of a telecommunications conveyance station in southern Taiwan with long term exposure to sulphuric acid vapour concentrations as high as 0.18 mg/m3. All three workers were diagnosed with NPC within a 5 month period between September 1992, and March 1993. Compared with 19 other healthy workers from the same building, these three workers with NPC had worked significantly longer in this building than had the others (mean (SD) (years): 12.7 (0.6) v 7.4 (4.4); p = 0.01). With an in situ nucleic acid hybridisation and immunostaining method for colocalised Epstein-Barr virus (EBV) and secretory component (SC) protein among biopsy specimens of these three patients with NPCs, it was found that some tumour cells did not contain EBV and SC protein staining signals. These results indicate that EBV infection is not the only risk factor for NPC and long term exposure to relatively low concentrations of sulphuric acid vapour may be associated with the development of NPC.  (+info)

Sulfuric acid on Europa and the radiolytic sulfur cycle. (5/440)

A comparison of laboratory spectra with Galileo data indicates that hydrated sulfuric acid is present and is a major component of Europa's surface. In addition, this moon's visually dark surface material, which spatially correlates with the sulfuric acid concentration, is identified as radiolytically altered sulfur polymers. Radiolysis of the surface by magnetospheric plasma bombardment continuously cycles sulfur between three forms: sulfuric acid, sulfur dioxide, and sulfur polymers, with sulfuric acid being about 50 times as abundant as the other forms. Enhanced sulfuric acid concentrations are found in Europa's geologically young terrains, suggesting that low-temperature, liquid sulfuric acid may influence geological processes.  (+info)

Biosynthesis of heparin/heparan sulfate: kinetic studies of the glucuronyl C5-epimerase with N-sulfated derivatives of the Escherichia coli K5 capsular polysaccharide as substrates. (6/440)

The D-glucuronyl C5-epimerase involved in the biosynthesis of heparin and heparan sulfate was investigated with focus on its substrate specificity, its kinetic properties, and a comparison of epimerase preparations from the Furth mastocytoma and bovine liver, which synthesize heparin and heparan sulfate, respectively. New substrates for the epimerase were prepared from the capsular polysaccharide of Escherichia coli K5, which had been labeled at C5 of its D-glucuronic and N-acetyl-D-glucosamine moieties by growing the bacteria in the presence of D-[5-(3)H]glucose. Following complete or partial ( approximately 50%) N-deacetylation of the polysaccharide by hydrazinolysis, the free amino groups were sulfated by treatment with trimethylamine.SO(3)complex, which yielded products that were recognized as substrates by the epimerase and released tritium from C5 of the D-glucuronyl residues upon incubation with the enzyme. Comparison of the kinetic properties of the two substrates showed that the fully N-sulfated derivative was the best substrate in terms of its K(m)value, which was significantly lower than that of its partially N-acetylated counterpart. The V(max)values for the E.coli polysaccharide derivatives were essentially the same but were both lower than that of the O-desulfated [(3)H]heparin used in our previous studies. Surprisingly, the apparent K(m)values for all three substrates increased with increasing enzyme concentration. The reason for this phenomenon is not entirely clear at present. Partially purified C5-epimerase preparations from the Furth mastocytoma and bovine liver, respectively, behaved similarly in terms of their reactivity towards the various substrates, but the variation in apparent K(m)values with enzyme concentration precluded a detailed comparison of their kinetic properties.  (+info)

A habitat for psychrophiles in deep Antarctic ice. (7/440)

Microbes, some of which may be viable, have been found in ice cores drilled at Vostok Station at depths down to approximately 3,600 m, close to the surface of the huge subglacial Lake Vostok. Two types of ice have been found. The upper 3,500 m comprises glacial ice containing traces of nutrients of aeolian origin including sulfuric acid, nitric acid, methanosulfonic acid (MSA), formic acid, sea salts, and mineral grains. Ice below approximately 3,500 m comprises refrozen water from Lake Vostok, accreted to the bottom of the glacial ice. Nutrients in the accretion ice include salts and dissolved organic carbon. There is great interest in searching for living microbes and especially for new species in deepest Antarctic ice. I propose a habitat consisting of interconnected liquid veins along three-grain boundaries in ice in which psychrophilic bacteria can move and obtain energy and carbon from ions in solution. In the accretion ice, with an age of a few 10(4) years and a temperature a few degrees below freezing, the carbon and energy sources in the veins can maintain significant numbers of cells per cubic centimeter that are metabolizing but not multiplying. In the 4 x 10(5)-year-old colder glacial ice, at least 1 cell per cm(3) in acid veins can be maintained. With fluorescence microscopy tuned to detect NADH in live organisms, motile bacteria could be detected by direct scanning of the veins in ice samples.  (+info)

Oxidized low density lipoproteins regulate synthesis of monkey aortic smooth muscle cell proteoglycans that have enhanced native low density lipoprotein binding properties. (8/440)

Oxidized low density lipoproteins (Ox-LDL) affect several biological processes involved in atherogenesis. However, it is not known whether Ox-LDL can regulate proteoglycan expression and thus affect arterial wall lipoprotein retention. This study evaluated whether Ox-LDL, as compared with native LDL, regulates proteoglycan expression by monkey arterial smooth muscle cells in vitro and whether proteoglycans synthesized in the presence of Ox-LDL exhibit altered lipoprotein binding properties. Ox-LDL stimulated glycosaminoglycan synthesis, as measured by (35)SO(4) incorporation, by 30-50% over that of native LDL. The effect was maximal after 72 h of exposure to 5 microg/ml of Ox-LDL. The molecular sizes of versican, biglycan, and decorin increased in response to Ox-LDL, as indicated by size exclusion chromatography and SDS-polyacrylamide gel electrophoresis. These effects could be mimicked by the lipid extract of Ox-LDL. These size increases were largely due to chain elongation and not to alterations in the ratio of (35)SO(4) to [(3)H]glucosamine incorporation. Affinity chromatography indicated that Ox-LDL stimulated the synthesis of proteoglycans with high affinity for native LDL. Ox-LDL also specifically stimulated mRNA expression for biglycan (but not versican or decorin), which was correlated with increased expression of secreted biglycan. Thus, Ox-LDL may influence lipoprotein retention by regulating synthesis of biglycan and also by altering glycosaminoglycan synthesis of vascular proteoglycans so as to enhance lipoprotein binding properties.  (+info)

Sulfuric acid , also spelled Sulphuric acid, sometimes called Oil Of Vitriol, or Hydrogen Sulfate battery acid, is a dense, colourless, oily, corrosive liquid; more sulfuric acid is produced than any other chemical. It has widely varied uses and plays some part in the production of nearly all manufactured goods. Pure sulfuric acid with a specific gravity of 1.85. freezes at 10.37° C , boils at 340° C and is soluble in all proportions in water. When heated, the pure acid partially decomposes into water and sulfur trioxide. Sulfuric acid is a very strong acid in aqueous solution; it is largely changed to hydrogen ions (H+) and sulfate ions (SO42-). Each molecule gives two H+ ions, thus sulfuric acid is dibasic, which forms both normal sulfates (with both hydrogens replaced, e.g., sodium sulfate, Na2SO4) and acid sulfates, also called bisulfates or hydrogen sulfates (with only one hydrogen replaced, e.g., sodium bisulfate, NaHSO4). Dilute solutions of sulfuric acid show all the behavior ...
Small droplets of sulfuric acid may exist in the outdoor air. You and your children have the greatest chances of inhaling the compound during times of high air pollution with sulfuric acid. This may lead to difficulty breathing. If you live near electrical, metal processing, or paper processing industries, you may also have a greater chance of exposure to sulfuric acid. When sulfuric acid is inhaled into the lungs in the form of small droplets that exist in air, these droplets are deposited within the lung and the ability of your respiratory tract to remove other small, unwanted particles may be decreased. A study has shown that children can have greater deposition of sulfuric acid in their lungs than adults due to childrens smaller airway diameters. Also, because children breathe more air per kilogram of body weight than adults, children may take in more sulfuric acid when they breathe the same contaminated air. Increased sensitivity has been witnessed in both animal studies with young guinea ...
Sulfuric acid has many uses. World production in 2001 was 165 million tons, worth about $8 billion US dollars. Uses include ore processing, fertilizer manufacturing, oil refining, wastewater processing, lead acid batteries, and combining chemicals for scientific reasons. For example, phosphate rocks are reacted with sulfuric acid to produce soluble phosphates, useful in fertilizers. This reaction is also used to make phosphoric acid, useful in soda. Potassium compounds are dissolved in sulfuric acid to produce potassium sulfate, useful in fertilizers. Ammonia is also reacted with sulfuric acid to produce ammonium sulfate. These three chemicals are solids and provide the three main minerals needed in plants. Lead acid batteries use sulfuric acid as their electrolyte. ...
Most thermochemical cycles being considered for producing hydrogen include a processing stream in which dilute sulfuric acid is concentrated, vaporized and then decomposed over a catalyst. The sulfuric acid vaporizer is exposed to highly aggressive conditions. Liquid sulfuric acid will be present at a concentration of |96 wt% (|90 mol %) H2SO4 and temperatures exceeding 400oC [Brown, et. al, 2003]. The system will also be pressurized, 0.7-3.5 MPa, to keep the sulfuric acid in the liquid state at this temperature and acid concentration. These conditions far exceed those found in the commercial sulfuric acid generation, regeneration and handling industries. Exotic materials, e.g. ceramics, precious metals, clad materials, etc., have been proposed for this application [Wong, et. al., 2005]. However, development time, costs, reliability, safety concerns and/or certification issues plague such solutions and should be considered as relatively long-term, optimum solutions.

Definition of sulfuric acid in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is sulfuric acid? Meaning of sulfuric acid as a legal term. What does sulfuric acid mean in law?
Sulphuric acid is an important factor in aerosol nucleation and growth. It has been shown that ions enhance the formation of sulphuric acid aerosols, but the exact mechanism has remained undetermined. Furthermore some studies have found a deficiency in the sulphuric acid budget, suggesting a missing source. In this study the production of sulphuric acid from SO2 through a number of different pathways is investigated. The production methods are standard gas phase oxidation by OH radicals produced by ozone photolysis with UV light, liquid phase oxidation by ozone, and gas phase oxidation initiated by gamma rays. The distributions of stable sulphur isotopes in the products and substrate were measured using isotope ratio mass spectrometry. All methods produced sulphate enriched in S-34 and we find an enrichment factor (delta S-34) of 8.7 +/- 0.4 parts per thousand (1 standard deviation) for the UV-initiated OH reaction. Only UV light (Hg emission at 253.65 nm) produced a clear non-mass-dependent ...
Sulphuric acid also known as oil of vitriol having molecular formula H2SO4 is a highly strong corrosive mineral acid. Sulphuric acid is pungent-ethereal, colorless to slightly yellow viscous liquid soluble in water at all concentrations. During production, sulphuric acid takes dyed dark brown color to intimate people of its strong hazard effects. Sulphuric acid shows different properties with different material depending on the concentration. Having strong acidic nature, sulphuric acid can harm materials such as metals, living tissues even stones at strong concentration. Sulphuric acid at high concentration can cause serious damage to eye as it burns the cornea of the eye causing permanent blindness if splashed into the eye..

THIS chief among the chemicals that keep the wheels of Americas war industry turning can be made right in your home laboratory. It is sulphuric acid, highly versatile and with distinctive properties that have earned for it the title, King of the Chemicals. And it is as simple to manufacture commercially as you will find it to be with a few odds and ends of bottles and jars on the kitchen table.. Essentially, sulphuric acid is a thick, oily, water solution of sulphur trioxide. Concentrated acid is made commercially by the contact process in which sulphur dioxide, produced by burning sulphur or roasting iron pyrites, is passed over a heated catalyst, which causes it to combine with oxygen of the air to form sulphur trioxide. Since the finely divided sulphur trioxide cannot be dissolved directly in water, it is added to concentrated sulphuric acid, forming a superconcentrated or fuming acid which is easily diluted to the required strength.. You may demonstrate this contact process in your ...

N2 - Glycated hemoglobin levels in hemolysate of normal and diabetic patients were determined by the 2,6-dimethylphenol:57.5% sulphuric acid conventional method and the values were 0.39±0.025 and 0.69±0.21 moles of hydroxymethylfurfural (HMF)/mole of globin, respectively. The mean increase in glycated hemoglobin values in diabetics (1.8 fold) was highly significant (p,0.001). A good correlation (r=0.95) was found between the glycated hemoglobin values obtained by this method and the phenohsulphuric acid method. The values obtained by former method were about 1.2-1.4 times the values by the phenohsulphuric acid method. This study indicates that conventional 2,6- dimethylphenol:57.5% sulphuric acid method is more sensitive for the estimation of glycated hemoglobin than any other method based on the same ...
Vitriol was widely considered the most important alchemical substance, intended to be used as a philosophers stone. Highly purified vitriol was used as a medium to react substances in. This was largely because the acid does not react with gold, often the final aim of alchemical processes. The importance of vitriol to alchemy is highlighted in the alchemical motto, a backronym,[2] Visita Interiora Terrae Rectificando Invenies Occultum Lapidem (Visit the interior of the earth and rectifying (i.e. purifying) you will find the hidden/secret stone).[3]. In the seventeenth century, the German-Dutch chemist Johann Glauber prepared sulfuric acid by burning sulfur together with saltpeter (potassium nitrate, KNO3), in the presence of steam. As the saltpeter decomposes, it oxidizes the sulfur to SO3, which combines with water to produce sulfuric acid. In 1736, Joshua Ward, a London pharmacist, used this method to begin the first large-scale production of sulfuric acid.. In 1746, in Birmingham, John ...
As a pH-reducing agent, a sulfuric acid regent is used during an acid demand test to determine how much acid to add to a swimming pool to bring down the pH to a balanced level. It is also used in testing total alkalinity by titration, where the sulfuric acid reagent is added drop-by-drop after adding a sodium thiosulfate to neutralize chlorine, and adding a total alkalinity indicator to turn the water sample green. The number of sulfuric acid reagent drops added to the mixture to turn the sample from green to red can be used to determine the amount of sodium bicarbonate (baking soda) to add to the swimming pool water..

The equation for the reaction is: H{2}SO{4} + 2NH{3} → (NH{4}){2}SO{4} [Numbers in braces are supposed to be subscripts, but I cant do them here.] This says that 1 mole of sulphuric acid reacts with 2 moles of nitrogen to create 1 mole of ammonium sulphate. 1 mole of a substance weighs the same as its atomic weight in grams. 1 mole of NH{3} weighs 14 + 3 × 1 = 17 g Thus 2 × 17 g = 34 g of ammonia react with 1 mole of sulphuric acid. To react with 500 g of ammonia requires 500 g ÷ 34 g/mol ≈ 14.7 moles of sulphuric acid Therefore there will be 51.0 - 14.7 = 36.3 moles of sulphuric acid left.

The melting range of the substance sulfuric acid, mono-C12-14 alkyl esters, compds. with triethanolamine (CAS 90583-18-9) was obtained as a result of the weight of evidence approach. The evidence includes guideline study (OECD Guideline 102, DSC method) with the other alkyl sulfates category member: sulfuric acid, C8-14 alkyl esters, compds. with triethanolamine (CAS 85665-45-8) as well as reliable literature data (DSC method) obtained for both dodecyl and tetradecyl sulphate, triethanolamine salt, i.e. main constituents of the substance CAS 90583-18-9. The data is consistent: it is expected that the melting of longer chain constituents (C12 and C14) can occur at somewhat higher temperatures than the melting of the substance which contains also shorter chain ones (C8 and C10). As it cannot be unambigously determined which temperature range is associated with particular constituents, the overall range from -4 °C (begin of melting of CAS 85665-45-8) to 76 °C (melting of tetradecyl sulphate, TEA ...
A new method was developed in this work for extraction of chitosan from the zygomycetes cell wall. It is based on the temperature-dependent solubility of chitosan in dilute sulfuric acid. Chitin is soluble in neither cold nor hot dilute sulfuric acid. Similarly chitosan is not soluble at room temperature but is dissolved in 1% H2SO4 at 121 degrees C within 20 min. The new method was developed to measure the chitosan content of the biomass and cell wall. The procedures were investigated by measuring phosphate, protein, ash, glucuronic acid, and degree of acetylation. The cell wall derivatives of fungus Rhizomucor pusillus were then examined by this new method. The results indicated 8% of the biomass as chitosan. After treatment with NaOH, the alkali-insoluble material (AIM) contained 45.3% chitosan. Treatment of AIM with acetic acid resulted in 16.5% acetic-acid-soluble material (AGSM) and 79.0% alkali- and acid-insoluble material (AAIM). AGSM is usually cited as pure chitosan, but the new method shows

Eliminating sulfuric acid injection in the NF feed at the City of Palm Coast site improved cartridge filter run times and led to a significant reduction in chemical consumption. The total annual savings in operation costs were estimated to be approximately $145,000. A laboratory analysis performed for this study indicated that the foulant matrix consisted of sulfur/metallic sulfides and organics. While, pH adjustment can reduce the membrane scaling potential, it can also lead to aggravated biofouling or inorganic fouling. As a result, groundwaters containing hydrogen sulfide, natural organic matter, and high levels of hardness compound their operational issues by using sulfuric acid pretreatment..

I try to say, that if you want to dissolve copper in dilute sulfuric acid you need some oxidizer, because dilute sulfuric acid havent oxidizing properties. So there isnt SO2 formation at all. Dilute sulfuric acid alone just dont react with copper. This can do only concentrated sulfuric acid which have oxidizing properties (so SO2 is produced as a product of reduction of sulfuric acid). This needs heating for reasonable speed of the reaction. Of course that you can add some peroxide for speeding things up, but it isnt necessary ...

Introduction. ACID - BASE TITRATION AIM The aim is to perform an experiment involving the titration of an acid and base to find the end-point of the titration in order to determine the molarity of the sulphuric acid. GENERAL BACKGROUND According to Bronsted and Lowry (1923) an acid is defined as a proton (H+) donor, and a base as a proton (H+) acceptor. For example, sulphuric acid, a strong acid, is a good proton donor while sodium hydroxide, a strong alkali (soluble base) contains the hydroxide ion (OH-) which is a strong proton acceptor. The alkali which produces this OH- ion will neutralize acids by the reaction: H+(aq) + OH-(aq) --, H2O(l) This reaction is common to all neutralization reactions between acids and alkalis in aqueous solution. It should be noted that in aqueous solutions the H+ ions exist in their hydrated forms H+(aq). The most accurate method of measurement is to run the acid into the alkali from a burette. This is known as neutralization by titration. Titration is a ...
Abstract  Exposure to strong acids such as sulfuric acid to either the skin or the gastrointestinal or respiratory mucosa will result respectively in significantâ€Âoccasionally fatalâ€Âcutaneous chemical burns as well as devastating corrosive damage to the respiratory and gastrointestinal tracts. Most injuries are accidental, but there are reports of using acids as weapons or as a means of suicide. The primary mechanism of acid injury is coagulative necrosis of the tissues.

An international team of researchers says it has discovered a new atmospheric compound that reacts with sulfur dioxide to form sulfuric acid, which produces acid rain, has negative respiratory effects on humans, and causes increased cloud formation. Reporting in Nature, the scientists from the U.S., Finland, and Germany identified the new compound as a type of carbonyl oxide, formed by the reaction of ozone with natural and manmade hydrocarbons, known as alkenes. When the carbonyl oxide compounds react with sulfur dioxide - which is primarily produced by coal and other fossil fuel combustion at power plants - large amounts of sulfuric acid are produced. The scientists say it is the first time that this complex new interaction of atmospheric compounds has been documented. Sulfuric acid creates acid rain that is harmful to terrestrial and aquatic life, and airborne sulfuric acid particles play the main role in the formation of clouds, an increase of which could help cool the planet. Smaller ...
Microbial extraction of oil from Jatropha kernels using whole cells of Bacillus pumilus yields 73% oil. The oil is liberated via degradation of hemicelluloses in which the majority kernel proteins were preserved. In investigating the effect of dilute sulfuric acid pretreatment on the enzymatic digestibility of the lignocellulosic components of Jatropha fruit biomass, we found that the seed shell and the seed cake were more recalcitrant to dilute sulfuric acid pretreatments than the fruit hull. The fruit hull pretreated with dilute sulfuric acid at optimum conditions (10% solid loading, 0.9% sulfuric acid, 30 min, 178 oC) followed by neutralization and a 24-h enzymatic hydrolysis with cellulases (GC220) gave the hydrolyzate with high sugar content. The hydrolyzate can be used as a substrate to produce ethanol by Saccharomyces cerevisiae in SSF process ...

Picture courtesy of: NOAA. According to NOAAs Earth Systems Research Laboratory (ESRL), Benjamin Franklin was the first person to suggest that major volcanic eruptions could emit enough ash and other particles into the atmosphere and that it could have a significant impact on short-term climate, even great distances from where the eruption occurred. How would this occur? Volcanic debris that is thrust into the troposphere and stratosphere can actually remain for months, up to a few years. This debris, like the sulfuric acid pictured above, turns into tiny droples of sulfuric acid in time. These sulfuric acid droplets are responsible for having an effect on climate because they can block incoming solar radiation from entering Earths lower atmoshpere, cooling the earth. Also, a warming component can exist as outgoing radiation from the earth is blocked by the acid particles. This warming component has a lesser effect on climate change than the cooling component and is a similar process to the ...

A process is described for leaching a value metal from an ore containing said value metal, the process including the steps of leaching the ore in the presence of hydrochloric acid so as to form a soluble metal-chloride salt in a leach solution; adding sulphuric acid and/or sulphur dioxide to the leach solution; recovering a solid metal-sulphate or metal-sulphite salt from the leach solution; regenerating hydrochloric acid; and continuously transferring at least a portion of the regenerated hydrochloric acid in solution to the vapour phase. The vapourised hydrochloric acid is then captured and returned to the leaching step. The sulphuric acid and/or sulphur dioxide may be added to the leach solution during or after the leaching step. The value metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal-sulphate or sulphite salt may be the value metal, or may be a metal of less value than the value metal
Related entry: Nectandra.-Bebeeru-Bark. SYNONYMS: Beberiae sulphas, Sulphate of bibirine, Sulphate of bebeerine.. Source.-An impure sulphate of an alkaloid obtained from nectandra or bebeeru barks. The salt is probably a mixture of beberine, nectandrine (this is probably identical with sipirine), and other alkaloidal. bodies.. Preparation.-The process for obtaining it is essentially the same as that for sulphate of quinine. The bark is at first freed of tannin and coloring matter by boiling it with carbonate of sodium; it is then exhausted by boiling in water acidulated with sulphuric acid, and the alkaloidal matter is thrown down from the concentrated acid liquor by means of carbonate of sodium. The impure bases thus separated are washed, dissolved, and neutralized with weak sulphuric acid, and the solution is treated with animal charcoal, concentrated, filtered again, and finally evaporated in thin layers in flat vessels. Any excess of acid must be carefully avoided, otherwise the salt will be ...

The sulphate should not lose more than 8 per cent. of its weight on drying at 100°. It should only slightly tinge concentrated sulphuric acid. Not more than a slight fluorescence should be noticeable in a solution (1 in 1000) in dilute sulphuric acid (limit of quinine and quinidine). If 5 decigrams be shaken with 20 mils of water at 15° for some time, 5 decigrams of sodium potassium tartrate added, and the mixture left with frequent shaking for an hour, the filtrate should not show more than a faint opalescence on the addition of a drop of solution of ...
A rather extensive degradation of cellulose and hemicelluloses was found in waterlogged oak wood samples from the ancient warship Vasa by size exclusion chromatography with the solvent system lithium chloride/N,N-dimethylacetamide (LiCl/DMAc). The degradation has mainly occurred after salvage of the wreck, probably as a consequence of keeping iron contaminated wood in contact with air. The most likely explanation is Fenton type of reactions degrading the wood polymers and oxidising reduced sulphur forms to sulphuric acid. An increased degradation rate of the Vasa wood can be anticipated in the future if the sulphuric acid cannot be neutralised and the oxidative reactions cannot be quenched.. ...

Sulfur dioxide is sometimes used as a preservative (E number: E220[2]) in alcoholic drinks,[3] or dried apricots and other dried fruits due to its antimicrobial properties. The preservative is used to maintain the appearance of the fruit rather than prevent rotting. This can give fruit a distinctive chemical taste. Sulfur dioxide is also a good reductant. In the presence of water, sulfur dioxide is able to decolorize substances that can be reduced by it; thus making it a useful reducing bleach for papers and delicate materials such as clothes. This bleaching effect normally does not last very long. Oxygen in the atmosphere reoxidizes the reduced dyes, restoring the color. Sulfur dioxide is also used to make sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. This is called the contact process. According to Claude Ribbe in The Crime of Napoleon, sulfur dioxide gas was used ...

Commercially nitrobenzene can be either produced in a batch or by a continuous process. Both batch and continuous processes employing mixed nitric and sulfuric acids are used to make nitrobenzene. The continuous process is favored over the batch process because its production capacity is much larger, it has lower capital costs and it entails more efficient labor usage. Reactors for the continuous process also usually utilized lower nitric acid concentrations, are smaller with more rapid and efficient mixing, and therefore have higher reaction rates. Nitrobenzene undergoes nitration, halogenation, and sulfonation much more slowly than does benzene. It may be reduced to a variety of compounds, depending on the reaction ...
A strong acid is an acid which completely dissociates (gives up its protons) in water. Some example strong acids include hydrochloric acid (HCl) and hydrobromic acid (HBr). Sulfuric acid is also a strong acid but it is a special case; it is diprotic, but only the first hydrogen completely dissociates in water. The highly reactive nature of such acids make them useful in the etching of materials, particularly metals. Strong acids are also used in tanning. The conjugate base for a strong acid is a weak base. In many cases the conjugate base simply acts as a spectator ion in a reaction. ...
Carbonyl sulfide is the most abundant sulfur compound naturally present in the atmosphere, at 6990500000000000000♠0.5±0.05 ppb, because it is emitted from oceans, volcanoes and deep sea vents. As such, it is a significant compound in the global sulfur cycle. Measurements on the Antarctica ice cores and from air trapped in snow above glaciers (firn air) have provided a detailed picture of OCS concentrations from 1640 to the present day and allow an understanding of the relative importance of anthropogenic and non-anthropogenic sources of this gas to the atmosphere.[6] Some carbonyl sulfide that is transported into the stratospheric sulfate layer is oxidized to sulfuric acid.[7] Sulfuric acid forms particulate which affects energy balance due to light scattering.[8] The long atmospheric lifetime of COS makes it the major source of stratospheric sulfate, though sulfur dioxide from volcanic activity can be significant too.[8] Carbonyl sulfide is also removed from the atmosphere by terrestrial ...
0058]The fundamental principles of the method for synthesizing these cellulose acylates are described by Migita et al. in Mokuzai Kagaku (Wood Chemistry), pp. 180-190 (Kyoritsu Shuppan, 1968). A typical synthesis method is a liquid phase acetylation method involving a carboxylic anhydride, acetic acid and sulfuric acid as catalyst. Specifically, a cellulose raw material such as cotton linter and wood pulp is pretreated with an appropriate amount of acetic acid, and then subjected to esterification by placing the pretreated cellulose raw material in a precooled liquid mixture for carboxylation to thereby synthesize a perfect cellulose acylate (the sum of the substitution degrees of the acyl groups at the 2-, 3- and 6-position amounting to almost 3.00). The liquid mixture for carboxylation generally contains acetic acid as solvent, a carboxylic anhydride as an esterifying agent and sulfuric acid as catalyst. It is a common practice to use the carboxylic anhydride in a stoichiometrically excess ...
The new process occurs in two steps. The first step uses existing methods to separate the hydrogen sulfide gas that naturally contaminates unprocessed oil from the base crude oil. The hydrogen sulfide gas is then sent through molten copper which filters out the sulfur and results in a stream of pure hydrogen gas with a copper sulfide byproduct. The hydrogen gas can be captured for later use in any number of industrial applications. In addition, the copper sulfide separates into pure copper and sulfuric acid when the copper sulfide reacts with air, allowing the copper to be reused. The sulfuric acid produced is also a valuable product used widely in the chemical and agricultural industries.. The separation of the oil and the hydrogen sulfide gas uses existing technology, but the use of molten copper to generate pure hydrogen gas from the hydrogen sulfide is new and is the first process that results in usable hydrogen gas. Most other processes result in losing the hydrogen as water.. The ...

Custom fiberglass, with its low maintenance, high performance, heat tolerance, and corrosion resistance is a go-to material in many industries for a multitude of applications. Sure, custom fiberglass sounds expensive. The reality of any situation is always more subtle. When considering the entire range of benefits over time, high-quality custom fiberglass that can be formulated to withstand a variety of acids, bases, chlorides, solvents, and oxidizers and outlast other popular materials of construction such as high-priced nickel alloys is a very cost-effective material.. Fiberglass materials formulated from high quality epoxy vinyl ester resins will outperform stainless steel in chemically aggressive environments including Sulfuric Acid. For example, in dilute form sulfuric acid is known to be extremely corrosive to carbon steel, yet properly formulated fiberglass can provide corrosion resistance.. With respect to operating environment (i.e. concentration, presence of water vapor, pressure, ...
Methanesulfonic acid (MSA) is an alternative to sulfuric acid electrolyte for metal deposition. The electrochemical nucleation and growth of Cu on a glassy carbon electrode in methanesulfonate was compared with sulfate baths. The overpotential for Cu deposition was much smaller in the MSA bath compared to the traditional sulfuric acid bath, and Cu nucleation occurred at a higher rate in the MSA bath. The measured diffusion coefficient value for Cu deposition from the MSA bath was 6.82x10(-6) cm(2)/s. UV-visible spectroscopic results confirmed that the coordination of Cu species was the same in both electrolytes. Cu electrodeposition on Ni sputtered Si substrate from the high efficiency MSA bath was photoresist-compatible with no void formation. One-dimensional Cu nanorods were also deposited through an anodized aluminum oxide template on a Ni evaporated seed layer substrate, showing potential applications as electrical interconnects in ultralarge scale integration (ULSI) and ...

Marquis reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of formaldehyde and concentrated sulfuric acid, which is dripped onto the substance being tested. The United States Department of Justice method for producing the reagent is the addition of 100 mL of concentrated (95-98%) sulfuric acid to 5 mL of 40% formaldehyde.[1]:12 Different compounds produce different color reactions. Methanol may be added to slow down the reaction process to allow better observation of the colour change. This is done by slowing down the polymerisation process.[citation needed] It was first discovered in 1896[2] and described by the Russian (Estonian) pharmacologist, Eduard Marquis (1871-1944) (Russian: Эдуард Маркус)[3] in his magister dissertation in 1896;[4] and named after him,[5] and was tested for the first time at the University of Dorpat. The reagent should be stored in the freezer for maximum shelf life[6] It is the ...
The first-ever well-aligned continuous macroscopic neat single-walled carbon nanotube (SWNT) fibers were produced using conventional spinning techniques. Neat SWNT fibers, containing no surfactant or polymer, were made by spinning dispersions of SWNTs in 102% sulfuric acid into different coagulants. The critical role of sulfuric acid in dispersing and aligning SWNTs during fiber formation has been explored. Characterization shows alignment greater than any other macroscopic neat SWNT material reported to-date while providing insight into the fundamental hierarchy and nature of SWNT fiber formation. Electrical, thermal, and mechanical measurements indicate that neat SWNT fibers hold tremendous potential for future applications.
B) ε-Benzoylaminocaproic Acid.-The rearrangement of 100 g. (0.88 mole) of pure cyclohexanone oxime (Note 3) is carried out in the following way. In a 1-l. beaker are placed a 10-g. portion of the oxime and 20 cc. of 85 per cent sulfuric acid (sp. gr. 1.783) (Note 4). The beaker is heated with a low flame and the contents are mixed with a rotary motion until bubbles first appear. The beaker is then removed from the flame immediately, and the violent reaction, which lasts a few seconds, is allowed to subside. The acid solution of ε-caprolactam is transferred to a 5-l. round-bottomed flask, and another 10-g. portion of the oxime is placed in the beaker and rearranged with sulfuric acid as before. The combined acid solution from the ten operations is diluted with 2.5 l. of water and boiled gently for one and one-half hours with 5 g. of decolorizing carbon. The solution is filtered and exactly neutralized to litmus with 50 per cent sodium hydroxide solution. About 510 g. of sodium hydroxide ...
The main way of synthesizing hydrobromic acid is the reaction between alkali metal bromides and diluted sulfuric acid. Care must be taken not to use concentrated sulfuric acid or another oxidizing acid, because these acids oxidize bromide to elemental bromine. Even with this reaction, the resulting acid may come out brown, contaminated with a small amount of bromine. Anhydrous HBr can be purified by letting the gas through a solution of phenol in tetrachloromethane. Azeotropic hydrobromic acid cannot be purified this way. However, azeotropic HBr can be re-distilled, which typically removes the yellow or brown color and gives clear, colorless acid. ...
