ABSTRACT:
The oxidation of methyl benzenes, such as toluene, with air or oxygen in the presence of acetic anhydride and sulfuric acid catalyst to form a phenolic acetate and methylene diacetate may be carried out under mild conditions when small amounts of benzaldehyde are added to the reaction.
The resulting acetates may then be pyrolyzed to yield phenolic compounds and formaldehyde, respectively.
