• Oxidation of p, p'-dimethylbenzophenone (1) with peracid in glacial acetic acid or acetic anhydride gave p-cresol ester (2) of p-toluic acid, which was hydrolyzed to yield p-toluic acid and p-cresol simultaneously. Amount of solvent and hydrogen peroxide, concentration of sulfuric acid catalyst and reaction temperature have been investigated and the optimum reaction conditions were found as follows: To 0.03 mole of (1) in 0.22 mole of glacial acetic acid, was added 4.8ml. of concn sulfuric acid. 0.05 mole of 30% hydrogen peroxide was added dropwise to the above mixture during 30 mins. and farther stirring was continued for 11 hrs. at the same temperature. Hydrolysis of the product (2) with sodium hydroxide solution yielded 94.4% toluic acid and 94.9% p-cresol respectivery.
