The liquid phase oxidation of benzyl alcohol is an important reaction for generating benzaldehyde and benzoic acid that are largely required in the perfumery and pharmaceutical industries. The current production systems suffer from either low conversion or over oxidation. From the viewpoint of economy efficiency and environmental demand, we are aiming to develop new high-performance and cost-ef...

An efficient and simple method for selective oxidation of secondary alcohols and oxidation of alkanes to ketones is reported. An in situ prepared catalyst is employed based on manganese(II) salts, pyridine-2-carboxylic acid, and butanedione, which provides good-to-excellent conversions and yields with high turnover numbers (up to 10 000) with H2 O2 as oxidant at ambient temperatures. In substra...

Of the various chemical methods described in the literature for the determination of ethyl alcohol (1) the majority are based upon the oxidation of the alcohol to acetic acid by means of potassium dichromate in the presence of a high concentration of sulfuric acid. Typical of these methods are the ones devised by Widmark (2) and by Nicloux (3). Widmark reports that it is not possible to calcula...

Retinene reductase, an enzyme which catalyzes the diphosphopyridine nucleotide-dependent reduction of vitamin A aldehyde (retinene) to vitamin A alcohol, was first demonstrated with homogenates of frog and cattle retinas (1, 2). Because crude rabbit liver extracts (3) and crystalline horse liver alcohol dehydrogenase (4) catalyze the oxidation of vitamin A into retinene, the general involvement...

Chronic alcohol consumption causes alcohol-induced lipogenesis and promotes hepatic injury by preventing the oxidation of hepatocellular fatty acids through the suppression of the activation of AMP-activated protein kinase (AMPK). HIMH0021, an active flavonoid compound, which is a component of the Acer tegmentosum extract, has been shown to protect against liver damage caused by alcohol consump...

Isopropyl has replaced ethyl alcohol in many such pharmaceutical preparations and cosmetics as mouth washes, dental solutions, and hair tonics. Although the physiology and toxicity of this material are fairly well known, a thorough knowledge of the metabolism involves a method for the separate determination of isopropyl alcohol and acetone, the chief product of its oxidation in the body. Many o...
