hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...

although antidote development should proceed in an orderly fashion from observation, to experimental and safety studies, to clinical trials, this sequence is not always precisely followed. the development of fomepizole as an antidote for toxic alcohol and glycol poisoning is an example of how this may not be the case. interest in the development of fomepizole was spurred in the 1960s. shortly t...

Ethylene glycol, a common antifreeze, coolant and industrial solvent, is responsible for many instances of accidental and intentional poisoning annually. Following ingestion, ethylene glycol is first hepatically metabolised to glycoaldehyde by alcohol dehydrogenase. Glycoaldehyde is then oxidised to glycolic acid, glyoxylic acid and finally oxalic acid. While ethylene glycol itself causes intox...

Occupational exposure to ethylene oxide was assessed among the workers remaining in direct contact with ethylene oxide or with ethylene oxide-sterilized instruments in 13 hospitals located in the city of Lódź and its suburbs. Individual dosimetry and stationary sampling methods were employed. The samples collected from the occupational environment were analysed by gas chromatography with mass d...

in this study, poly(ethylene-co-vinyl alcohol) (evoh) as a novel biocompatible polymeric scaffold was surface modified by succinylation to get evohs and further pegylated to improve structural properties using methoxypolyethylene glycol (5000 da) succinate (pegs) along with targeting with retinoic acid (ra) to get final modified active and passive targeted conjugate (pegs-evohs-ra) to evaluate ...

Ethylene is a gaseous plant hormone involved in many physiological processes including senescence, fruit ripening, and defence. Here the effects of pollination and wound-induced ethylene signals on transcript accumulation of benzoyl CoA:benzyl alcohol/phenylethanol benzoyltransferase (PhBPBT) are shown in Petuniaxhybrida cv. Mitchell 'Diploid' (MD). In petunia, PhBPBT is responsible for the bio...

We have developed a liquid material for embolization of arteriovenous malformations that is a mixture of ethylene vinyl alcohol copolymer and metrizamide dissolved in dimethyl sulfoxide. Upon contact with blood, dimethyl sulfoxide rapidly diffuses into the blood and forms an ethylene vinyl alcohol copolymer elastic soft sponge that obstructs both the feeder and the nidus. The material, which is...

Ethyl alcohol is produced in the United States by two major procedures, fermentation and chemical synthesis. Practically all current industrial ethyl alcohol is manufactured synthetically from petroleum and natural gas. All beverage alcohol is produced through the fermentation of cereal grains, molasses. and other materials with high starch and sugar content. Chemically, both alcohols are essen...
