generated by fermentation reactions that naturally take place in the intestines. The body always has a small amount of ethanol being transported across the intestine walls. As a result, the body has an enzyme to metabolize ethanol called ethanol oxidase. (You might want to think about this. ...

When biodiesel is exposed to oxygen, the oxygen itself attaches to the bis-allylic site directly adjacent to the double bonds. This initiates the auto-oxidation chain reactions and ultimately forms peroxides. The process of peroxidation promotes auto-oxidation by three steps: initiation, propagation,...
The long-wave (位 < 3000 ) photo-oxidation of polystyrene in solution at 25掳C has been studied osmometrically. Two types of chain scission have been observed: a purely photo process which occurs completely independently of oxygen and wh... JB Lawrence,NA Weir - 《Journal of Polymer Scienc...

Two themes recur in discussions of the mechanism of the action of ionizing radiations and their after effects in aqueous systems:— (i) The production of H atoms and HO radicals and, if oxygen is present, HO2 radicals, and their reactions together with those of other radicals formed by the...
Vinyl polymerization is another proposed mechanism for the degradation of biodiesel. In this mechanism, a CC bond is created when a carbon-based free radical is added directly to an olefinic carbon and another free radical is created. This mechanism is also least important when excess oxygen is ...

Inphlogiston …and sulfur underwent reactions of oxidation or reduction (deoxidation); and he showed that the newly discovered element oxygen was always involved. Although a number of chemists—notably Joseph Priestley, one of the discoverers of oxygen—tried to retain some form of the phlogiston ...
