Thermal dissociation of ethylene glycol vinyl ether.
The pyrolysis of ethylene glycol vinyl ether (EGVE), an initial product of 1,4-dioxane dissociation, was examined in a diaphragmless shock tube (DFST) using laser schlieren densitometry (LS) at 57 ± 2 and 122 ± 3 Torr over 1200-1800 K. DFST/time-of-flight mass spectrometry experiments were also performed to identify reaction products. EGVE was found to dissociate via two channels: (1) a molecul...
متن کاملDependence of an alkyl glycol-ether monooxygenase activity upon tetrahydropterins.
Glyceryl-ether monooxygenase (1-alkyl-sn-glycerol,tetrahydropteridine: oxygen oxidoreductase, EC 1.14.16.5) catalyzes the oxidative cleavage of 1-O-alkyl glycerol or glycol derivatives to a long-chain aldehyde and the glycerol or glycol derivative. The specificity for tetrahydropterins of a similar, perhaps identical, enzyme that cleaves O-hexadecyl ethylene glycol in rat liver microsomes was e...
متن کاملMicroencapsulation of Butyl Stearate as Phase Change Material by Melamine Formaldehyde Shell for Thermal Energy Storage
Butyl stearate as a phase change material was microencapsulated within melamine-formaldehyde resin using emulsion polymerization. Morphology and thermal specification of produced microcapsules were studied by Fourier transform infrared spectroscopy, FT-IR, scanning electron microscopy, SEM, and Differential scanning calorimetry analysis, DSC. FT-IR spectra validated the existence of the butyl s...
متن کاملSynthesis of Functionalized Aryl-vinyl Ethers as Building Blocks and Auxiliaries in Organic Synthesis
5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.
متن کاملGenotoxicity of glycol ethers.
The genetic toxicology of glycol ethers is reviewed. Ethylene glycol monomethyl ether (EGME) and diglyme have been more extensively studied than other members of this series. Most results indicate a lack of genotoxic potential, but certain tests have yielded positive responses with certain compounds. Ethylene glycol monoethyl ether (EGEE) induced sister chromatid exchanges and chromosomal aberr...
