The dehalogenation in vivo of brominated aliphatic hydrocarbons such as methyl bromide (1) and bromochloromethane (2) has been demonstrated by recovery of inorganic bromide from blood and urine. The intracellular formation of bromide and methyl alcohol from methyl bromide has been advanced as an explanation for its prolonged toxic effect (3). Evidence for the splitting of chlorinated aliphatic ...

Toxic alcohols that clinicians commonly encounter are ethylene glycol, methanol, and isopropanol. Adults ingest these either for suicidal intent or to achieve inebriation, since these substances are readily available and cheaper than alcohol. Nevertheless, assorted alcohols are used very often in many applications and any alcohol can be toxic if ingested in large enough quantities. Toxic alcoho...

Abstract A methodology for the oxidation of α-trifluoromethyl alcohols to corresponding trifluoromethyl ketones is presented. catalytic quantity a nitroxide used, and potassium persulfate serves as terminal oxidant. The proves effective aromatic, heteroaromatic, conjugated alcohol substrates. It can be extended nonfluorinated secondary and, in this case, applied range aliphatic alcohols.

Compared to other melon types, Cantaloupe Charentais melons are highly aromatic with a major contribution to the aroma being made by aliphatic and branched esters. Using a transgenic line in which the synthesis of the plant hormone ethylene has been considerably lowered by antisense ACC oxidase mRNA (AS), the aliphatic ester pathway steps at which ethylene exerts its regulatory role were found....

ONIOM calculation is carried out to estimate the acidity of five aliphatic alcohols before and after adsorbing on the tip of (8,0) single-walled carbon nanotube. The ONIOM method is performed using a combination of density functional theory and AM1 semiemperical method for alcohols and their corresponding conjugated bases. Deprotonation Gibbs free energies of alcohols are calculated and compare...

The meadow spittlebug, Philaenus spumarius L. (Hemiptera, Aphrophoridae) is a commonly found vector of Xylella fastidiosa Wells et al. (1987) strain subspecies pauca associated with the "Olive Quick Decline Syndrome" in Italy. To contribute to the knowledge of the adult P. spumarius chemoreceptivity, electroantennographic (EAG) responses of both sexes to 50 volatile organic compounds (VOCs) inc...

Individual poly(methyl methacrylate)/MWCNT doped with sulfuric acid were polymerized in situ to yield individual nanotubes increased electrical conductivity. In the presence of aliphatic alcohol vapors various diameters, Nanocomposites measured as a function time. These sensor responses are particularly rapid due huge surface volume ratio, consistent diameter, and limited amount active material...

A Rh porphyrin on carbon black was shown to catalyze the electro-oxidation of several aliphatic alcohols (ethanol, 1-propanol, and 2-propanol) and benzyl alcohols. The overpotentials for alcohol oxidation were very low. The reaction mechanism and substrate specificity are discussed.
