Abstract

Procédé de production d'acides carboxyliques par oxydation catalytique d'hydrocarbures aromatiques, suivant lequel la réaction d'oxydation est effectuée avec un courant gazeux ayant une teneur déterminée d'avance en oxygène et catalysé par un complexe catalytique obtenu à partir d'aldéhydes et/ou de cétones de bas poids moléculaire et de sels de métaux de transition et la réaction d'oxydation est exécutée dans un solvant constitué par un acide monocarboxylique à bas point d'ébullition qui est un solvant tant du complexe catalytique que des hydrocarbures aromatiques de départProcess for the production of carboxylic acids by catalytic oxidation of aromatic hydrocarbons, according to which the oxidation reaction is carried out with a gas stream having a predetermined content of oxygen and catalyzed by a catalytic complex obtained from aldehydes and / or low molecular weight ketones and transition metal salts and the oxidation reaction is carried out in a solvent consisting of a low boiling point monocarboxylic acid which is a solvent of both the catalytic complex and the aromatic hydrocarbons of departure
