  • Process for producing an aryl-imido-peralkanoic acid by oxidizing the corresponding aryl-imido-alkanoic acid with hydrogen peroxide
    Patent number: 5208340
    Abstract: Process for producing an aryl-imido-peralkanoic acid by means of the peroxidation with H.sub.2 O.sub.2 of the corresponding alkanoic (non-peroxy) acid, in the presence of a strong acid with a pKa value equal to, or lower than 3, and in the presence of a halogenated solvent, characterized in that said solvent is CH.sub.2 Cl.sub.2 or CHCl.sub.3, that the amount of alkanoic acid submitted to peroxidation is equal to or smaller than the solubility threshold of said alkanoic acid (in said solvent) and that a solution of said acid in said solvent is reacted with H.sub.2 O.sub.2 (at 10.degree.-35.degree. C.), with the molar ratio of said strong acid to said alkanoic acid being lower than 2.
