The oxidation mechanism of aldehydes with permanganate was studied in acidic and alkaline media on acetaldehyde, propionaldehyde, pivalaldehyde (2,2鈥 -dimethylpropanal) and chloral substrates. On addition of water to acetaldehyde dissolved in organic solvents the rate increased, and therefore it may...
This invention relates tc the direct oxidation of aldehydes to the corresponding acid anhydrides. An object of this invention is the production of aliphatic acid anhydrides by the direct oxidation of aliphatic aldehydes in the liquid phase at atmospheric pressure and to produce the anhydrides...收藏...
The information available on the oxidation of aldehydes permits one to interpret it as a chain mechanism involving free radicals and yielding a rather re-active peracid. The peracid reacts in turn with aldehyde, producing two acid molecules. The pronounced effect of small amounts of inhibitors ...

The kinetics of oxidation of substituted toluenes by pyridinium fluorochromate(VI) (PFC), C5H5N\\overset+HCrO3F−, in aqueous acetic acid, in the presence of perchloric acid, have been studied. The main products are the corresponding aldehydes. While each of the oxidation is first order wit...
The ability of the Te=O bond to activate the propane CH bond depends sensitively upon the number of V atoms that are coupled through a bridging O to the Te=O center. Based on this ROA mechanism, we suggest synthetic procedures aimed at developing a single phase MMO catalyst with ...
