  • enough phenol
  • Interesting, we distill enough phenol for over 6 months (eg. (bio.net)

  • The public pressure soon forced Schweitzer and Edison to end the phenol deal, with the embarrassed Edison subsequently sending his excess phenol to the U.S. military, but by that time the deal had netted the plotters over two million dollars and there was already enough phenol to keep Bayer's aspirin plant running. (wikipedia.org)
  • carbolic acid
  • Joseph Lister (1827-1912), an English surgeon at the Glasgow Royal Infirmary, used solutions of phenol dissolved in water, known as carbolic acid , to kill germs in wounds and to sterilize medical equipment, drastically cutting down the number of deaths caused by infections. (angelo.edu)
  • The simplest of the class is phenol, which is also called carbolic acid C 6H 5OH. (wikipedia.org)
  • acid
  • Phenol is acid as such when melted. (bio.net)
  • In this method, a mixture of TE (or Tris-Ethylenediaminetetraacetic acid) and phenol is combined with an equal volume of an aqueous DNA sample. (wikipedia.org)
  • Phenol is a useful compound for breaking down superfluous cell materials that would otherwise contaminate the nucleic acid sample. (wikipedia.org)
  • There are two reasons why phenol makes such an effective purifier for nucleic acid samples. (wikipedia.org)
  • It is a weak acid with pKa = 8.00 at 20 °C (68 °F). A solution of phenol red is used as a pH indicator, often in cell culture. (wikipedia.org)
  • Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid- or base-catalysed. (wikipedia.org)
  • cyclic
  • In several sources, the structure of phenol red is shown with the sulfur atom being part of a cyclic group, similar to the structure of phenolphthalein. (wikipedia.org)
  • compound
  • Phenols are named after the parent compound, phenol (hydroxybenzene). (angelo.edu)
  • Phenol was also the first compound to be used in antiseptic surgery. (angelo.edu)
  • To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions (or, probably more common, dividing the dilution factor at which the tested substance shows activity by the dilution factor at which phenol shows comparable activity). (wikipedia.org)
  • Phenolsulfonphthalein
  • Phenol red (also known as phenolsulfonphthalein or PSP) is a pH indicator frequently used in cell biology laboratories. (wikipedia.org)
  • Phenol red was used in the phenolsulfonphthalein test to estimate the overall blood flow through the kidney and is now obsolete. (wikipedia.org)
  • enzyme
  • The systematic name of this enzyme class is phenol,NADPH:oxygen oxidoreductase (2-hydroxylating). (wikipedia.org)
  • The systematic name of this enzyme class is S-adenosyl-L-methionine:phenol O-methyltransferase. (wikipedia.org)
  • The systematic name of this enzyme class is UDP-glucose:phenol beta-D-glucosyltransferase. (wikipedia.org)
  • estrogen
  • Phenol red is a weak estrogen mimic, and in cell cultures can enhance the growth of cells that express the estrogen receptor. (wikipedia.org)
  • aspirin
  • The Great Phenol Plot was a conspiracy by the German Government during the early years of World War I to divert American-produced phenol away from the manufacture of high explosives that supported the British war effort, to the production of aspirin by the German-owned Bayer company, who could no longer import phenol from Britain. (wikipedia.org)
  • Substance
  • When listed numerically, the figure expressing the disinfecting power of a substance by relating it to the disinfecting power of phenol may be a function of the standardized test performed. (wikipedia.org)
  • clinical
  • Auramine phenol stain is a stain used in clinical microbiology and histology to identify tuberculosis mycobacteria. (wikipedia.org)
  • water
  • The second is that phenol has a density of 1.07 g/cm3, which is higher than the density of water (1.00 g/cm3). (wikipedia.org)
  • High levels of bromine can convert phenol red to bromophenol red (dibromophenolsulfonephthalein, whose lowered pKa results in an indicator with a range shifted in the acidic direction - water at pH 6.8 will appear to test at 7.5). (wikipedia.org)
  • Phenol, formaldehyde, water and catalyst are mixed in the desired amount, depending on the resin to be formed, and are then heated. (wikipedia.org)
  • Being thermosets, hydroxymethyl phenols will crosslink on heating to around 120 °C to form methylene and methyl ether bridges through the elimination of water molecules. (wikipedia.org)
  • tissue
  • Phenol exerts a marked corrosive action on any tissue of contact when ingested, inhaled or after skin exposure. (inchem.org)
  • Since the color of phenol red can interfere with some spectrophotometric and fluorescent assays, many types of tissue culture media are also available without phenol red. (wikipedia.org)
  • species
  • There are two types of auramine phenol stains, 1 and 2 to stain mycobacterium species and cryptosporidium respectively. (wikipedia.org)
  • characteristic
  • Phenol poisoning can be recognised by the characteristic acrid odour on the breath or it can be detected in the urine, which may be dark coloured. (inchem.org)
  • group
  • This article is about the class of chemicals containing a phenol group. (wikipedia.org)
  • The initial reaction in all cases involves the formation of a hydroxymethyl phenol: HOC6H5 + CH2O → HOC6H4CH2OH The hydroxymethyl group is capable of reacting with either another free ortho or para site, or with another hydroxymethyl group. (wikipedia.org)
  • careful
  • Schweitzer sold the remainder of the phenol at a considerable profit, being careful to distribute it to only non-war-related industries. (wikipedia.org)
  • indicator
  • i.e. the phenol red can be seen as an indicator of the process. (bio.net)
  • Phenol red, sometimes labelled with a different name, such as "Guardex Solution #2", is used as a pH indicator in home swimming pool test kits. (wikipedia.org)
  • form
  • Two natural phenols from two different categories, for instance a flavonoid and a lignan, can combine to form a hybrid class like the flavonolignans . (wikipedia.org)
  • When studied in mass spectrometry, phenols easily form adduct ions with halogens. (wikipedia.org)
  • directly
  • One reacts phenol and formaldehyde directly to produce a thermosetting network polymer, while the other restricts the formaldehyde to produce a prepolymer known as novolac which can be moulded and then cured with the addition of more formaldehyde and heat. (wikipedia.org)
  • units
  • Phenol reacts with formaldehyde at the ortho and para sites (sites 2, 4 and 6) allowing up to 3 units of formaldehyde to attach to the ring. (wikipedia.org)
  • The phenol units are mainly linked by methylene and/or ether groups. (wikipedia.org)
  • The molecular weights are in the low thousands, corresponding to about 10-20 phenol units. (wikipedia.org)
