The ability of several electron acceptors to promote the Gluconobacter oxydans catalyzed oxidation of glycerol was investigated, p-Benzoquinone was the most effective electron acceptor. The reaction rate obtained with p-benzoquinone was higher than the maximal rate with the natural electron acceptor

β¦ Synopsis
This paper reports the production of 2-phenylacetaldehyde from 2-phenylethanol by acetic bacteria. Several mains of acetic bacteria were investigated and three were found to be effective for this bioconversion. Different conditions (different C source for the microorganisms, pH, substrate concentration, cell immobilization) were tested with yields ranging from 30 to 52.6%.

The Ο-value of -1.8 for the oxidation of para-substituted 1-phenylethanols by sodium hypochlorite in acetic acid suggests that ketone is formed directly from alcohol by loss of a hydride. The kinetic isotope effect is 3.0. When the disappearance of oxidant is followed by iodometric titration, 5-nona
During the wet oxidation of contaminated wastewaters, the destruction of low molecular weight carboxylic acid intermediates such as acetic, glyoxalic, and oxalic acids is often the rate-controlling step. Oxidation of acetic acid, a very recalcitrant intermediate, requires compelling treatment severi
The hexacyanoferrate(II1)-thallium(1) reaction in aqueous acetic acid containing large concentrations of hydrochloric acid is considerably accelerated both by hydrogen and chloride ions as well as increasing acetic acid in the medium. The experimental results obey the rate law (1) where PI to p6 (1
