Abstract

Procedure for continuous oxidation by air, in liquid phase, of an aromatic hydrocarbon provided with at least one oxidizable side chain, in the presence of salts and/or heavy metal halides as catalyst and an aliphatic carboxylic acid as solvent, characterized because it is operated in a series of reactors in which the fluids, kept under pressure, circulate in partial or total backflow, without condensation of the vapors between each reactor or addition of fresh solvent in the last reactor, being continuously recycled in oxidation the recovered mother-waters.
