CA 2649716

Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise a combination comprising a palladium component, an antimony component and/or a bismuth component, and one or more Group 4, 5, 6 or 14 metal or metalloid components. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture.

L'invention concerne des compositions catalytiques destinées à la transformation de matières premières aromatiques substituées en produits oxydés comprenant des dérivés d'acide carboxylique aromatique des matières premières aromatiques substituées, lesdites compositions comprenant un mélange comprenant un composant de palladium, un composant d'antimoine et/ou un composant de bismuth, ainsi qu'un ou plusieurs composés métalliques ou métalloïdes du groupe 4, 5, 6 ou 14. L'invention concerne également un procédé d'oxydation de matières premières aromatiques substituées, ledit procédé comprenant la mise en contact de la matière première avec de l'oxygène en présence d'une telle composition catalytique dans un mélange réactionnel liquide.
