A process is disclosed for the oxidation of esters of para- and meta-methyl-substituted phenols to the corresponding aromatic carboxylic acid in the presence of a promoter comprising an anhydride of a lower aliphatic carboxylic acid and a heavy metal catalyst with or without the presence of bromine. The resulting carboxylic acids are useful in liquid crystal polymers and polymers useful in engineering plastics.
