Title
(EN) PRODUCTION OF AROMATIC CARBOXYLIC ACIDS
(FR) PRODUCTION D'ACIDES CARBOXYLIQUES AROMATIQUES
Abstract
(EN) A process for the production of an aromatic carboxylic acid comprising contacting in the presence of a catalyst, within a continuous flow reactor, one or more precursors of the aromatic carboxylic acid with an oxidant, such contact being effected with said precursor(s) and the oxidant in an aqueous solvent comprising water under supercritical conditions or near supercritical conditions close to the supercritical point such that said one or more precursors, oxidant and aqueous solvent constitute a substantially single homogeneous phase in the reaction zone, wherein the contact of at least part of said precursor with said oxidant is contemporaneous with contact of said catalyst with at least part of said oxidant.
(FR) L'invention concerne un procédé de production d'acides carboxyliques aromatiques, consistant à mélanger un ou plusieurs précurseurs d'acide carboxylique aromatique avec un agent oxydant en présence d'un catalyseur, dans un réacteur à flux continu. Ledit mélange est effectué avec le ou les précurseurs et l'agent oxydant dans un solvant aqueux contenant de l'eau sous des conditions critiques ou sous des conditions quasiment supercritiques, à proximité du point supercritique, de manière que le ou les précurseurs, l'agent oxydant, et le solvant aqueux constituent une phase homogène essentiellement unique dans la zone de réaction. Le mélange d'au moins une partie dudit précurseur avec ledit agent oxydant est effectué au même moment que le mélange dudit catalyseur avec au moins une partie dudit agent oxydant.
