Abstract
Oxidation of methyl benzenes with air or oxygen to form a phenolic acetate and formaldehyde or methylene diacetate may be carried out in the presence of acetic acid, phosphorus pentoxide, benzaldehyde and an acid catalyst. The resulting acetates may then be pyrolyzed to yield phenolic compounds and formaldehyde, respectively.
