Lipophilicity determination of some potential photosystem II inhibitors on reversed-phase high-performance thin-layer chromatography. (1/539)

The retention characteristics of 25 2-cyano-3-methylthio-3-substituted amine-acrylates are determined using reversed-phase thin-layer chromatography (RP-TLC) with methanol-water mixtures as eluents. The relationship between Rm values and partition coefficients (C log P) are established. The Rm values decrease linearly with increasing methanol concentration in the eluent. The Rm values extrapolated to zero organic modifier concentration (Rm0) in the eluent are highly related to C log P. The Rm0 value can be used to evaluate the lipophilicity of this kind of compound.  (+info)

Demonstration of a new mammalian isoleucine catabolic pathway yielding an Rseries of metabolites. (2/539)

1. Normal human urine contains small amounts (less than 4 mg/g of creatinine) of 2-ethylhydracrylic acid, formed, we believe, by a previously undisclosed endogenous catabolic pathway for the oxidation of a newly described series of R metabolites of isoleucine. 2. Urinary excretion of 2-ethylhydracrylic acid is variably increased in defects of isoleucine oxidation at distal steps in the catabolic pathway (3-oxoacyl-CoA thiolase deficiency and methylmalonyl-CoA mutase deficiency) and is diminished when proximal steps of the oxidative pathway are blocked as in branched-chain oxo acid decarboxylase deficiency ('maple-syrup-urine' disease). 3. Precursors of R-pathway metabolites [R(-)-2-methylbutyrate and 2-ethylacrylate ] lead to increased 2-ethylhydracrylate excretion in the mammal(rat, rabbit and dog); the corresponding S metabolites [S(+)-2-methylbutyric acid and tiglic acid ], when given in equimolar amounts, have little effect on its excretion, suggesting that little or no interconversion between S and R metabolites occurs in vivo. 4. Studies with 2H-labelled precursors indicate that conversion of R 2-methylbutyrate into 2-ethylhydracrylic acid occurs by a direct pathway (apparently via 2-ethylacrylic acid). 5. The further oxidation of 2-ethylhydracrylic acid to ethylmalonic acid was demonstrated, and may be analogous to S-metabolite oxidation via methyl malonate. 6. Valine metabolites do not interact with the R=isoleucine pathway under the conditions of these experiments in vivo.  (+info)

Relative developmental toxicities of acrylates in rats following inhalation exposure. (3/539)

The developmental toxicities of seven acrylates were studied in Sprague-Dawley rats after inhalation exposure for 6 h/day, during days 6 to 20 of gestation. The exposure concentrations were: for acrylic acid, 50, 100, 200, or 300 ppm; for methyl acrylate, 25, 50, or 100 ppm; for ethyl acrylate, 25, 50, 100, or 200 ppm; for butyl acrylate, 100, 200, or 300 ppm; for ethylhexyl acrylate, 50, 75, or 100 ppm; for hydroxyethyl acrylate, 1, 5, or 10 ppm; and for hydroxypropyl acrylate, 1, 5, or 10 ppm. No treatment-related increases in embryo/fetal mortality or fetal malformations were observed after exposure to any of these acrylates. Fetal toxicity, indicated by reduced fetal body weight, was observed after exposure to 300 ppm acrylic acid, 100 ppm methyl acrylate, 200 ppm ethyl acrylate, and 200 or 300 ppm butyl acrylate in the presence of overt signs of maternal toxicity. While there was evidence of maternal toxicity, no significant developmental toxic effects were observed after exposure to ethylhexyl acrylate, hydroxyethyl acrylate, or hydroxypropyl acrylate at any concentration. These results indicate that inhaled acrylic acid, methyl acrylate, ethyl acrylate, butyl acrylate, ethylhexyl acrylate, hydroxyethyl acrylate, and hydroxypropyl acrylate are not selectively toxic to the embryo or fetus.  (+info)

A new carboxylesterase from Brevibacterium linens IFO 12171 responsible for the conversion of 1,4-butanediol diacrylate to 4-hydroxybutyl acrylate: purification, characterization, gene cloning, and gene expression in Escherichia coli. (4/539)

A carboxylesterase that is responsible for conversion of 1,4-butanediol diacrylate (BDA) to 4-hydroxybutyl acrylate (4HBA) was found in Brevibacterium lines IFO 12171, and purified to homogeneity. The purified enzyme was active toward a variety of diesters of ethylene glycol, 1,4-butanediol, and 1,6-hexanediol. The K(m) and kcat of the enzyme for BDA were 3.04 mM and 203,000 s-1, respectively. The reaction with the purified enzyme gave 98 mM 4HBA from 100 mM BDA for 60 min. The enzyme gene was cloned from the chromosomal DNA of the bacterium. The open reading frame encoding the enzyme was 1176 bp long, corresponding to a protein of 393 amino acid residues (molecular mass = 42,569 Da). The deduced amino acid sequence contained the tetra peptide motif sequence, STTK, and the serine residue was confirmed to be the catalytic center of BDA esterase by site-directed mutagenesis for several amino acid residues. The gene was expressed in Escherichia coli under the control of the lac promoter, and the gene product (a fusion protein with 6 amino acid residues from beta-galactosidase) showed the same catalytic properties as the enzyme from the parent strain.  (+info)

Allergic contact dermatitis to acrylates in disposable blue diathermy pads. (5/539)

We report 2 cases of elicitation of allergic contact dermatitis to acrylates from disposable blue diathermy pads used on patients who underwent routine surgery. Their reactions were severe, and took approximately 5 weeks to resolve. Both patients gave a prior history of finger tip dermatitis following the use of artificial sculptured acrylic nails, which is a common, but poorly reported, cause of acrylate allergy. Patch testing subsequently confirmed allergies to multiple acrylates present in both the conducting gel of disposable blue diathermy pads, and artificial sculptured acrylic nails. We advocate careful history taking prior to surgery to avoid unnecessary exposure to acrylates in patients already sensitized.  (+info)

Kinetic and inhibition studies on substrate channelling in the bifunctional enzyme catalysing C-terminal amidation. (6/539)

A series of experiments has been conducted to investigate the possibility that substrate channelling might occur in the bifunctional forms of enzymes carrying out C-terminal amidation, a post-translational modification essential to the biological activity of many neuropeptides. C-terminal amidation entails sequential action by peptidylglycine mono-oxygenase (PAM, EC 1.14.17.3) and peptidylamidoglycolate lyase (PGL, EC 4.3.2.5), with the mono-oxygenase catalysing conversion of a glycine-extended pro-peptide into the corresponding alpha-hydroxyglycine derivative, which is then converted by the lyase into amidated peptide plus glyoxylate. Since the mono-oxygenase and lyase reactions exhibit tandem reaction stereospecificities, channelling of the alpha-hydroxy intermediate might occur, as is the case for some other multifunctional enzymes. Selective inhibition of the mono-oxygenase domain by competitive ester inhibitors, as well as mechanism-based mono-oxygenase inactivation by the novel olefinic inhibitor 5-acetamido-4-oxo-6-phenylhex-2-enoate (N-acetylphenylalanyl acrylate), has little to no effect on the kinetic parameters of the lyase domain of the AE from Xenopus laevis. Similarly, inhibition of the lyase domain by the potent dioxo inhibitor 2,4-dioxo-5-acetamido-6-phenylhexanoate has little effect on the activity of the monooxygenase domain in the bifunctional enzyme. A series of experiments on intermediate accumulation and conversion were also carried out, along with kinetic investigations of the reactivities of the monofunctional and bifunctional forms of PAM and PGL towards substrates and inhibitors. Taken together, the results demonstrate the kinetic independence of the mono-oxygenase and lyase domains, and provide no evidence for substrate channelling between these domains in the bifunctional amidating enzyme.  (+info)

ACE inhibition and glucose transport in insulinresistant muscle: roles of bradykinin and nitric oxide. (7/539)

Acute administration of the angiotensin-converting enzyme (ACE) inhibitor captopril enhances insulin-stimulated glucose transport activity in skeletal muscle of the insulin-resistant obese Zucker rat. The present study was designed to assess whether this effect is mediated by an increase in the nonapeptide bradykinin (BK), by a decrease in action of ANG II, or both. Obese Zucker rats (8-9 wk old) were treated for 2 h with either captopril (50 mg/kg orally), bradykinin (200 micrograms/kg ip), or the ANG II receptor (AT(1) subtype) antagonist eprosartan (20 mg/kg orally). Captopril treatment enhanced in vitro insulin-stimulated (2 mU/ml) 2-deoxyglucose uptake in the epitrochlearis muscle by 22% (251 +/- 7 vs. 205 +/- 9 pmol. mg(-1). 20 min(-1); P < 0.05), whereas BK treatment enhanced this variable by 18% (249 +/- 15 vs. 215 +/- 7 pmol. mg(-1). 20 min(-1); P < 0.05). Eprosartan did not significantly modify insulin action. The BK-mediated increase in insulin action was completely abolished by pretreatment with either the specific BK-B(2) receptor antagonist HOE 140 (200 micrograms/kg ip) or the nitric oxide synthase inhibitor N(omega)-nitro-L-arginine methyl ester (50 mg/kg ip). Collectively, these results indicate that the modulation of insulin action by BK likely underlies the metabolic effects of ACE inhibitors in the insulin-resistant obese Zucker rat. Moreover, this modulation of insulin action by BK is likely mediated through B(2) receptors and by an increase in nitric oxide production and/or action in skeletal muscle tissue.  (+info)

Glutathione-dependent metabolism of cis-3-(9H-purin-6-ylthio)acrylic acid to yield the chemotherapeutic drug 6-mercaptopurine: evidence for two distinct mechanisms in rats. (8/539)

cis-3-(9H-Purin-6-ylthio)acrylic acid (PTA) is a structural analog of azathioprine, a prodrug of the antitumor and immunosuppressive drug 6-mercaptopurine (6-MP). In this study, we examined the in vitro and in vivo metabolism of PTA in rats. Two metabolites of PTA, 6-MP and the major metabolite, S-(9H-purin-6-yl)glutathione (PG), were formed in a time- and GSH-dependent manner in vitro. Formation of 6-MP and PG occurred nonenzymatically, but 6-MP formation was enhanced 2- and 7-fold by the addition of liver and kidney homogenates, respectively. Purified rat liver glutathione S-transferases enhanced 6-MP formation from PTA by 1.8-fold, whereas human recombinant alpha, mu, and pi isozymes enhanced 6-MP formation by 1.7-, 1.3-, and 1.3-fold, respectively. In kidney homogenate incubations, PG accumulation was only observed during the first 15 min because of further metabolism by gamma-glutamyltranspeptidase, dipeptidase, and beta-lyase to yield 6-MP, as indicated by the use of the inhibitors acivicin and aminooxyacetic acid. Based on these results and other lines of evidence, two different GSH-dependent pathways are proposed for 6-MP formation: an indirect pathway involving PG formation and further metabolism to 6-MP, and a direct pathway in which PTA acts as a Michael acceptor. HPLC analyses of urine of rats treated i.p. with PTA (100 mg/kg) showed that 6-MP was formed in vivo and excreted in urine without apparent liver or kidney toxicity. Collectively, these studies show that PTA is metabolized to 6-MP both in vitro and in vivo and may therefore be a useful prodrug of 6-MP.  (+info)

Acrylate polymers belong to a group of polymers which could be referred to generally as plastics. They are noted for their transparency, resistance to breakage, and elasticity. They are also commonly known as acrylics or polyacrylates. Acrylate polymer is commonly used in cosmetics such as nail polish as an adhesive. Acrylate monomers used to form acrylate polymers are based on the structure of acrylic acid, which consists of a vinyl group and a carboxylic acid terminus. Other typical acrylate monomers are derivatives of acrylic acid, such as methyl methacrylate in which one vinyl hydrogen and the carboxylic acid hydrogen are both replaced by methyl groups, and acrylonitrile in which the carboxylic acid group is replaced by the related nitrile group. Other examples of acrylate monomers are: Methacrylates Methyl acrylate Ethyl acrylate 2-Chloroethyl vinyl ether 2-Ethylhexyl acrylate Hydroxyethyl methacrylate Butyl acrylate Butyl methacrylate TMPTA Acrylic elastomer is a general term for a type of ...

Triethanolamine (1), N-methyldiethanolamine (2) and N,N-dimethylethanolamine (3) have been used in conjunction with the 2-(2-chlorophenyl)-4,5-diphenylimidazolyl radical and triplet benzophenone to initiate the polymerisation of lauryl acrylate. The radical abstracts a hydrogen atom from the amine to generate an alpha-aminoalkyl radical. From the order of reactivity of the amines towards the lophyl (triarylimidazolyl) radical i.p. 2 ,, 1 , 3 it is concluded that hydrogen-atom abstraction occurs rather than electron followed by proton transfer. The imidazolyl radicals abstract hydrogen from thiols in a similar fashion more effectively to give thiyl radicals which initiate polymerisation of the acrylate. By following the progress of the polymerisation reactions by RTIR spectroscopy, it was concluded that the effectiveness of the amines to reduce oxygen inhibition is 1 , 3 , 2. The ability of the amines to act as synergists in the polymerisation of thin films of lauryl acrylate initiated by lophyl ...

The development of biocompatible polymers using thiol-acrylate Michael addition reactions between not only acrylates and thiols but also between amines and acrylates were demonstrated. The synthesis of an in situ tertiary amine catalyst initiates the propagation steps of the polymerization process by subsequently reacting with trimethylolpropane tris (3-mercaptopropionate) (TMPTMP). A few notable characteristics of this reaction are tunable gel times, the capability of reaching high polymer conversion and suitable mechanical strength. With addition of hydroxyapatite to the polymeric phase and foaming, a porous bone composite was produced. Further osteogenisis and in vivo work using the PETA-co-TMPTMP (HA) composite material was analyzed. The PETA-co-TMPTMP-co-TMTMP with 20%HA showed an increase in osteogenic potential higher than the FDA approved PCL over the 21-day study. The rats did not exhibit any severe systemic responses from the polymer implant, and an increase in bone growth was observed for the

The propionate, or propanoate ion, is C2H5COO− (the conjugate base of propionic acid). A propionic, or propanoic, compound is a small salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH3CH2CO2 or simply EtCO2. Propionates should not be confused with propenoates (commonly known as acrylates), the ions/salts/esters of propenoic acid (also known as 2-propenoic acid or acrylic acid). Propionate is observed to be among the most common short-chain fatty acids produced by human gut microbiota in response to indigestible carbohydrates (fiber) in the diet.[2] A study in mice suggests that propionate is produced by the bacteria of the genus Bacteroides in the gut, and that it offers some protection against Salmonella there.[3] ...

Regardless of whether your warhead is reversible or not, it is important that different members of the library have similar reactivities: if the inherent reactivities of the fragments are different, it will be difficult to distinguish inherent binding energies from chemical reactivities. One of the problems with acrylamides is that subtle changes in chemical structures can have dramatic effects on intrinsic reactivities. The new paper compares rate constants of two acrylamides reacting with a low molecular-weight thiol, and finds that one reacts 2,000-fold faster than the other. The researchers tested three other classes of electrophiles - vinylsulfonamides, aminomethyl methyl acrylates, and methyl vinylsulfones - and found that these had narrower ranges of reactivity. They chose acrylates and built a set of 100 acrylate-modified fragments. Happily, when 50 of these were tested for reactivity, there was only a 2.4-fold difference between the most reactive and the least reactive members ...
The radical addition co-polymerisation 2-hydroxyethylmethacrylate and butylacrylate is carried out in a continuously operating Buss-Kneader. To calculate temperature profiles over the length of the kneader the heal balance is solved. For the heat transfer coefficient a model based on the penetration theory, is used. This model is experimentally verified. The reaction kinetics of the radical addition polymerisation are studied in a differential scanning calorimeter. The polymerisation kinetics are modeled using non-stationary radical concentrations. The calculated temperature profiles over the length of the Buss-Kneader are a good approximation of the experimental data.

In previous investigations, the authors have examined the adsorption of albumin, immunoglobulin, and fibrinogen to a series of acrylate polymers with different backbone and side-group flexibility. The authors showed that protein adsorption to acrylates with high flexibility, such as poly(lauryl methacrylate) (PLMA), tends to preserve native conformation. In the present study, the authors have continued this work by examining the conformational changes that occur during the binding of complement factor 3 (C3) and coagulation factor XII (FXII). Native C3 adsorbed readily to all solid surfaces tested, including a series of acrylate surfaces of varying backbone flexibility. However, a monoclonal antibody recognizing a "hidden" epitope of C3 (only exposed during C3 activation or denaturation) bound to the C3 on the rigid acrylate surfaces or on polystyrene (also rigid), but not to C3 on the flexible PLMA, indicating that varying degrees of conformational change had occurred with binding to different ...

Ian Davenport, President of Davenport International Associates LLC said the US acrylic acid supply problems of 2010 are now behind us with American Acryls running well, Dow Deer Park operating at high rates and new investments planned here and at Clear Lake. Economic reasons for not making SAP had diminished due to the downturn-related decline in demand for acrylates in paints. New SAP capacity being built in the East will raise annual global output from around 2 million tonnes to 2.8 million tonnes by 2014. 230,000 tonnes of this will be in China (San Dia, BASF and Danson), 108,000 tonnes in Korea (LG Chemical), 90,000 tonnes in Indonesia (Nippon Shokubai) and 84,000 tonnes in Japan (NS and Sumitomo Seika). Evonik will start an 80,000 tonne SAP plant in Saudi Arabia, and BASF are putting a 60,000 tonne plant into Brazil. The growth is driven by the major diaper producers (KC, P&G, SCA and Unicharm) who will use 50% of the increased production in responding to the increasing demand for diapers ...

Autori: M. Teodorescu,S. G. Gaynor and K. Matyjaszewski. Editorial: American Chemical Society, Macromolecules, 33(7), p.2335-2339, 2000.. Rezumat:. Halide anions have been used as complexing ligands in iron-mediated ATRP, in both direct and reverse ATRP. In direct ATRP, iron(II) bromide complexed with ammonium and phosphonium chloride, bromide or iodide salts has been shown to catalyze the polymerization of both styrene and (meth)acrylates in a controlled manner under appropriate conditions. The experimental molecular weights increased linearly with monomer conversion and were close to the calculated values. The polymerization rates and polydispersities (Mw/Mn = 1.1 - 1.4) were dependent on the monomer employed. Reverse ATRP, initiated by AIBN/FeBr3/onium salts, led to a controlled polymerization of both methyl methacrylate and methyl acrylate, while for styrene uncontrolled molecular weights and high polydispersities were obtained, presumably due to the involvement of the cationic ...

Pressing demands for high power and high energy densities in novel electrical energy storage units have caused reconsiderations regarding both the choice of battery chemistry and design. Practical concerns originating in the conventional use of flammable liquid electrolytes have renewed the interests of using solvent-free polymer electrolytes (SPEs) as solid ionic conductors for safer batteries.. In this thesis work, SPEs developed from two polymer host structures, polyethers and polycarbonates, have been investigated for all-solid-state Li- and Li-ion battery applications. In the first part, functional polyether-based polymer electrolytes, such as poly(propylene glycol) triamine based oligomer and poly(propylene oxide)-based acrylates, were investigated for 3D-microbattery applications. The amine end-groups were favorable for forming conformal electrolyte coatings onto 3D electrodes via self-assembly. In-situ polymerization methods such as UV-initiated and electro-initiated polymerization ...

Some synthetic bone graft are made of calcium carbonate, which start to decrease in usage because it is completely resorbable in short time which make the bone easy to break again.. Tricalcium phosphate which now used in combination with hydroxylapatite thus give both effect osteoconduction and resorbability.. Polymers such as some microporous grades of PMMA and various other acrylates (such as polyhydroxylethylmethacrylate aka PHEMA), coated with calcium hydroxide for adhesion, are also used as alloplastic grafts for their inhibition of infection and their mechanical resilience and biocompatibility. Calcifying marine algae such as Corallina officinalis have a fluorohydroxyapatitic composition whose structure is similar to human bone and offers gradual resorption, thus it is treated and standardized as "FHA (Fluoro-hydroxy-apatitic) biomaterial" alloplastic bone grafts.. ...
The abundant availability of cellulose resources and the favourable mechanical properties of its microfibrillated compounds makes them as good candidate for reinforcing agents in biocomposites. However, problems in homogeneous dispersive and distributive mixing of the cellulose additives due to their highly hydrophilic nature, often restrict the full capability of bio-based composites. Traditionally, surface modification of microfibrillated cellulose is often performed by introducing chemical moieties such as silanes, acrylates, vinyl etc. In view of developing a more sustainable and functional design of interface engineering, a new method is presented where nanoparticles including plant oil or wax are deposited onto the fiber surface and the required hydrophobicity can be controlled by thermal release of the hydrophobic moieties from the surface under thermal curing. In this work, the surfaces of microfibrillated cellulose are modified through decoration with poly(styrene-co-maleimide) ...

Electron beam- (EB-) induced graft polymerization of acrylic acid and the subsequent immobilization of arginine-glycine-aspartic acid (RGD) peptide onto nanopatterned polycaprolactone with parallel grooves is reported. A high concentration of carboxylic groups was introduced onto the polymer substrate by EB-induced polymerization of acrylic acid. In the coupling of the RGD peptide to the carboxylated polymer surface a three-step peptide immobilization process was used. This process included the activation of surface carboxylic acid into an active ester intermediate by use of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS), the introduction of disulfide groups by use of 2-(2-pyridinyldithio)ethanamine tie hydrochloride (PDEA), and final immobilization of the peptide via a thioldisulfide exchange reaction. The extent of coupling was measured by UV spectroscopy. A preliminary study of the in vitro behavior of keratinocytes (NCTC 2544) cultured on the ...

There is growing interest in the development of biomimetic matrices that are simultaneously cell-friendly, allow rapid vascularization, exhibit enough mechanical integrity to be comfortably handled and resist mechanical stresses when implanted in the site of interest. Meeting all these requirements with a single component material has proved to be very challenging. The hypothesis underlying this work was that hybrid materials obtained by combining scaffolds with bioactive hydrogels would result in a synergy of their best properties: a construct with good mechanical properties, easily handled and stable thanks to the scaffold; but also, because of the gel, cell-friendly and with enhanced oxygen and nutrients diffusion, and promoter of cell colonization. Moreover, such a composite material would also be useful as a controlled release system because of the gels incorporation. Poly (ethyl acrylate) (PEA) scaffolds prepared with two different morphologies were envisaged to provide the mechanical ...

In a hydrolysis study conducted by Ricerca Inc. (BAMM 1990), the half-life of 14C-butyl acrylate in water at pH 11 was determined to be approximately 243 minutes. There was less than 2 % hydrolysis of 14C-butyl acrylate at pH 3 and pH 7 during the 28 day period. Approximate hydrolysis half-life values for pH 3 and pH 7, calculated using initial and final 14C-butyl acrylate concentrations, were 2800 days at pH 3 and 1100 days at pH 7. Therefore, the substance will hydrolyse slowly in contact with water under environmental conditions. Hydrolysis will not contribute significantly to the degradation of n-butyl acrylate under environmental conditions. ...

A mathematical model describing chemical kinetics of transesterification of palm-based methyl esters with trimethylolpropane has been developed. The model was developed by utilizing nonlinear regression method, which is an efficient and powerful way to determine rate constants for both forward and reverse reactions. A comparison with previous study which excludes the reverse reactions was made. The model was based on the reverse mechanism of transesterification reactions and describes concentration changes of trimethylolpropane, monoesters and diesters production. The developed model was validated against data from the literature. The reaction rate constants were determined using MATLAB version 7.2 and the ratios of rate constants obtained were well in agreement with those reported in the literature. A good correlation between model simulations and experimental data was observed. It was proven that both methods were able to predict the rate constants with plausible accuracy.

Laymans explanation: Acrylic acid is a colorless liquid that has an irritating bitter odor and was discovered by Josef Redtenbacher, a German chemist. This substance is miscible with water and most organic solvents. Known also as 2-propeonic acid, this plant molecule occurs naturally in marine algae and has been found in the rumen fluid of sheep. Acrylic acid has been found to polymerize easily when exposed to heat, light, or metals so, therefore a polymerization inhibitor is added to commercial for storage. The acid is used in the manufacture of plastics, floor polish, paint formulations, leather finishings, and paper coatings. Exposure to the liquid occurs primarily in the workplace and can irritate the skin, eyes, and mucous membranes of humans. Acrylic acid has not been classified as a carcinogen. ...

Since the early 1990s there has been a steady growth within both academia and industry with regards to the use of flow reactors for the synthesis of chemical compounds due to the increase in reaction control afforded.1-7 In general, flow chemical synthesis offers several advantages over batch chemistry. For example, the reactors provide excellent heat transfer meaning reaction temperatures can be rapidly changed including accessing different sequentially linked temperature zones or facilitating super heating of solvents within an easily pressurised reactor. Mixing within flow channels can also be additionally enhanced generating more consistent reaction domains leading to better control and improvements in yield and purity. Automation of flow reactions enables better process control expedited via direct in-line analysis which can also be used in reaction feedback loops (RFL) and design of experiment (DoE) routines.8-16 Additional aspects of enhanced safety and the flexibility to conduct ...
