Abstract

Un método para minimizar o prevenir la pérdida de catalizador y/o la precipitacion de oxido metálico en un proceso para la produccion de un ácido carboxílico aromático, donde dicho proceso comprende poner en contacto uno o más precursores del ácido carboxílico aromático con un oxidante en un reactor, en presencia de un catalizador que comprende una sal metálica, donde dicho contacto se efectua entre dicho(s) precursor(es) y el oxidante en un solvente acuoso que comprende agua bajo condiciones supercríticas o casi supercríticas, donde (i) dicho método comprende el paso de agregar un componente ácido que comprende uno o más ácidos en la zona de reaccion de oxidacion; (ii) el contacto de al menos parte de dicho catalizador con dicho oxidante es en presencia de dicho componente ácido; y (iii) dicho componente ácido comprende uno o más ácidos orgánicos.A method to minimize or prevent the loss of catalyst and / or the precipitation of metal oxide in a process for the production of an aromatic carboxylic acid, wherein said process comprises contacting one or more precursors of the aromatic carboxylic acid with an oxidant in an reactor, in the presence of a catalyst comprising a metal salt, where said contact is made between said precursor (s) and the oxidant in an aqueous solvent comprising water under supercritical or almost supercritical conditions, where (i) said method it comprises the step of adding an acid component comprising one or more acids in the oxidation reaction zone; (ii) the contact of at least part of said catalyst with said oxidant is in the presence of said acid component; and (iii) said acid component comprises one or more organic acids.
