Abstract
Catalytic oxidation process of an aromatic substance, characterized in that a liquid mixture of said aromatic substance is prepared with a synergistic mixed solvent enclosing at least one acid of the group comprising acetic acid and its homologs and the benzoic acid and its homologs and, at least, a benzoic substance, as well as with a synergistic mixed catalyst composed of salts of at least one acid and of at least two metals; then an oxygenated gas is bubbled into said mixture at a temperature comprised between about 100 and 320º C, under a pressure at least equal to the vapor tension of said mixture at said temperature, until the transformation of at least a part of said aromatic substance in an oxidation product.
