Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise solid particles comprising palladium in combination with at least one of antimony, bismuth and gold, and optionally, an additional metal or metalloid component effective to promote activity or selectivity of the palladium and antimony, bismuth or gold for oxidation to aromatic carboxylic acids. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such catalytic compositions in a liquid reaction mixture.

L'invention concerne des compositions catalytiques pour convertir des matériaux d'alimentation aromatiques substitués en produits oxydés comprenant des dérivés acide carboxylique aromatique des matériaux d'alimentation aromatiques substitués, lesdites compositions comprenant des particules solides comprenant du palladium en association avec un ou plusieurs antimoine, bismuth et or, et facultativement un composant métallique ou métalloïde supplémentaire efficace pour favoriser l'activité ou la sélectivité du palladium et de l'antimoine, du bismuth ou de l'or pour l'oxydation en acides carboxyliques aromatiques. Un procédé d'oxydation de matériaux d'alimentation aromatiques substitués consiste à mettre en contact le matériau d'alimentation avec de l'oxygène en présence de telles compositions catalytiques dans un mélange réactionnel liquide.
