The hydrocarbon is oxidized in oxygen or air in a liquid phase in an organic solvent under alkaline conditions, in the presence of a catalyst selected from the group consisting of metal tetraphenylporphins, metal acetylacetonates, metal phthalocyanines and mixtures thereof. The oxidation is capable of proceeding generally at room temperature and atmospheric pressure.
