Reverse osmosis separation of particular organic solvent mixtures by a perfluorodioxole copolymer membrane

Reverse osmosis (RO) separation of organic solvent mixtures where solvent molecular weights are < 100 Da is challenging especially for powerful solvents that swell most uncrosslinked polymers. To avoid polymer swelling by solvents, a particular perfluoropolymer, perfluoro-2,2-dimethyl-1,3-dioxole copolymerized with tetrafluoroethylene, (PDD-TFE), designated CMS-7, was studied. This amorphous glassy extremely hydrophobic copolymer has a very high free volume (FV) fraction. The maximum dimension of FV regions is less than similar to 0.65 nm allowing only single solvent molecule permeation. Further, interactions between polarity, dimensions and shapes of solvent molecules with those of polymer FV elements can lead to extraordinarily selective permeation. RO separation of the following binary systems through a thin 1.67 mu m film of this polymer supported on an e-PTFE support was studied over 1000-3500 kPa feed pressure: N-Methyl-2-pyrrolidone (NMP)-toluene; dimethylformamide (DMF)-toluene; dimethylsulfoxide (DMSO)-toluene; NMP-methanol; n-butanol-ethanol. Pure toluene appeared as permeate for three polar aprotic-aromatic systems from highly toluene-rich feeds; the membrane rejected polar molecules having dimensions similar to those of toluene. High osmotic pressure of the feed mixtures employed vis-a-vis feed pressures used reduced toluene permeation flux and the range of separable feed mixtures. Pure methanol permeate was obtained from particular polar aprotic-polar protic NMP-methanol mixtures due to significantly smaller methanol dimensions. Pure ethanol permeate was also similarly obtained from a particular mixture with n-butanol, a case of polar protic1-polar protic2 system where ethanol molecules were smaller. Such novel and clean-cut pressure-driven separations may be due to various combinations of the dimensions of the solvent molecules and the polymer FV regions, high polymer hydrophobicity, polarity of the aprotic/protic solvents and very low swelling of the polymer. Solvent sorption studies of dense polymers provide an insight into swelling of the polymer by the solvent and potential solvent-specific interactions. Sorption studies using 25 mu m polymer samples for polar aprotic solvents, NMP, DMF, DMSO, yielded very low levels of sorption, 0.4-0.9 wt%; those for toluene and methanol were already known to be only 1.34 and 1.2 wt% respectively. Permeation behaviors of other solvent mixtures, toluene-n-heptane, NMP-tetrahydrofuran, methanol-water, ethanol-water as well as individual phases of the immiscible mixture of NMP and the nonpolar solvent n-heptane were also studied. To improve understanding, permeation of pure water in reverse osmosis mode was also investigated. Application of 98760-08-8, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 98760-08-8 is helpful to your research.

Effect of annealing temperature on antireflection property and water contact angle of fluorine-based hydrophobic films by a sol-gel technique

Crack-free and smooth surfaces of poly[4,5-difluoro 2,2-bis-(trifluoroinethyl)-1,3 dioxole]-co-tetrafluoroethylene (TFE-co-TFD) films have been deposited by sol-gel technique on polished AISI 440C steel and quartz substrates. The deposited films have been subjected to annealing at different temperatures ranging from 100 to 500 degreesC for 1 h in argon atmosphere. The as-deposited and annealed films (below 300 degreesC) on quartz have shown antireflection behaviour in the UV region. Surface properties of the films have been examined by employing scanning electron microscopy, energy dispersive X-ray analyser, for morphology and elemental composition. Adhesion strength failure was measured by scratch resistance test technique indicated good adhesion of the films on the substrate. It was found that as the annealing temperature increased from 100 to 400 degreesC, nanostructured sphere like balls were formed which in turn has shown increase in the contact angle for water from 122degrees to 247degrees. No change in the water contact angle (122degrees) has been observed when the films deposited at room temperature were heated in air from 30 to 80 degreesC indicating thermal stability of the coating.

Preparation and Reactions of Certain Racemic and Optically Active Cyanohydrins Derived from 2-Chlorobenzaldehyde, 4-Fluorobenzaldehyde, Benzo[d][1,3]-dioxole-5-carbaldehyde and 2,3-Dihydrobenzo[b][1,4]dioxine-6-carbaldehyde. Antimicrobial and in vitro Antitumor Evaluation of the Products

THE CHEMOENZYMATIC reaction of selected aldehydes, namely 2-chlorobenzaldehyde (1a), 4-fluorobenzaldehyde (1b), benzo[d][1,3] dioxole-5-carbaldehyde (1c) and/or 2,3-dihydrobenzo [b] [1,4]dioxine-6-carbaldehyde (1d) with hydrogen cyanide in presence of (R)-oxynitrilase (R)-Pa HNL [EC 4.1.2.10] from almonds, as a chiral catalyst, gave the optically active cyanohydrin enantiomers (R)2a-c, respectively. Acetone cyanohydrin (3), was also used, as a transcyanating agent, to give the same products. The racemic cyanohydrins (R, S)-2a-d have been synthesized, as well, by treating compounds 1a-d with aqueous potassium cyanide solution in presence of a saturated solution of sodium metabisulphite (Na2S2O5). The optical purity of cyanohydrins (R)-2a-c was determined through their derivatization with (S)-naproxen chloride (S)-5 to the respective diastereomers (R, 2S)-6a-c which were obtained in diastereomeric excess (de) values up to 93 % (H-1 NMR). Heating compounds (R)-2a, b and / or their racemic analogues (R, S)-2a-c with concentrated hydrochloric acid gave the respective alpha-hydroxycarboxylic acids 7a-c. Moreover, reduction of cyanohydrins (R, S)-2b,c under different conditions resulted in a hydrodecyanation giving the respective primary alcohols 8a, b. Structures and configurations of the new compounds were confirmed with compatible elementary microanalyses and spectroscopic (IR, H-1 NMR, C-13 NMR, MS and single crystal X-ray crystallography) measurements. The antimicrobial activity of derivatives 6a-d against four bacterial species (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and two fungi (Aspergillus flavus and Candida albicans) were undertaken. Moreover, compounds (R,2S)-6b, (R, 2S)(S, 2S)-6b and (R, 2S)-6c were screened for their in virto antitumor activity against three human solid cancer cell lines (HCT 116, HepG2 and MCF-7). In general, the tested compounds were found inactive or showed weak activities in comparison with the standard drugs.

Toxicological evaluation and metabolism of two N-alkyl benzamide umami flavour compounds: N-(heptan-4-yl)benzo[d][1,3]dioxole-5-carboxamide and (R)-N-(1-methoxy-4-methylpentan-2-y1)-3,4-dimethylbenzamide

Toxicological evaluations of two N-alkyl benzamide umami flavour compounds, N-(heptan-4-yl) benzo[d][1,3]dioxole-5-carboxamide (S807, CAS 745047-51-2) and (R)-N-(1-methoxy-4-methylpentan2-y1)-3,4-dimethylbenzamide (S9229, CAS 851669-60-8), were completed for the purpose of assessing their safety for use in food and beverage applications. Both 5807 and 59229 undergo rapid oxidative metabolism by both rat and human liver microsomes in vitro. In pharmacokinetic studies in rats, the systemic exposure to 59229 on oral administration is very low at all doses (% F < 1%), while that of 5807 demonstrated a non-linear dose dependence. In metabolism studies in rats, hydroxylation of the C-4 aryl methyl group was found to be the dominant metabolic pathway for 59229. The dominant metabolic pathway for 5807 in the rat involved oxidative scission of the methylenedioxy moiety to produce the corresponding 3,4-dihydroxybenamide which is further converted by Phase II metabolic enzymes to the 3- and 4-0-methyl ethers as well as their corresponding glucuronides. Both 5807 and 59229 were not found to be mutagenic or clastogenic in vitro, and did not induce micronuclei in polychromatic erythrocytes in vivo. In a subchronic oral toxicity study in rats, the no-observed-effect-level (NOEL) for 5807 was 20 mg/kg bw/day when administered in the diet for 13 weeks. The no-observed-adverse-effect-level (NOAEL) for 59229 in rats was 100 mg/kg bw/day (highest dose tested) when administered in the diet for 28 consecutive days.
