Hydrogenolytic redn. of an aldehyde to an alcohol in a diluting agent is claimed in the presence of a suitable monolithic catalyst at a H2 pressure of 0.01-7.0 MPa and -10 to 200 degrees C with the alcohol being isolated from the reaction mixt.....
The alcohol-flush reaction occurs in Asians who inherit the mutantALDH2*2 allele that produces an inactive aldehyde dehydrogenase enzyme. In these individuals, high blood acetaldehyde levels are believed to be the cause of the unpleasant symptoms that follow drinking. We measured the alcohol eliminat...

Methyl-t-butyl ether t-Butyl alcohol Buckley et al. (1997) The Use of Adducts as Biomarkers of Toxic Solvent and Gas Exposure Parent compounds and/or their metabolites may form adducts with macromolecules such as protein or DNA. These adducts may also be used as biomarkers of exposure and/...
4 . Liquor production in order to reduce aldehyde content, should be less with GuKang, rice, or to the materials for steamed processing.白酒生产中为了降低醛类含量,应少用谷糠、稻壳,或对辅料预先进行清蒸处理。 5 . An aldehyde is prepared from the dehydrogenation of an alcohol and hence the nam...
Aldehydes can be reduced to alcohols or oxidized to carboxylic acids, and undergo a variety of addition and condensation reactions, for example, addition of cyanide in the cyanohydrin synthesis, or condensation with another aldehyde in aldol reactions. History The name may be derived from the ...
Reactive aldehydes are formed as the end products of numerousoxidative reactions, including oxidation of alcohol and amino groups and through the addition of oxygen to unsaturated double bonds. In particular, the formation of α,β-unsaturated aldehydes as oxidation products is important in that the ...
mixture comprising a carboxylic acid and a metal cation, which method comprises: contacting the aldehyde mixture with a basic separating medium, and subsequently or simultaneously contacting with an acidic separating medium; use of the treated aldehyde mixture to prepare an alcohol; and the alcohol.收...
These patients may be able to drink ordinarily, because frequency and dose of habitual alcohol drinking has been shown to be influenced by ALDH2 activity (Takeshita et al., 1994). F o u r of the alcohol-habitant L H O N patients had the onset of optic nerve disease at an unusually ...
