Abstract

L'invention porte sur un procédé de fabrication d'un acide carboxylique aromatique par oxydation de composés alkyl aromatiques. Le composé alkyl aromatique est oxydé dans un réacteur d'oxydation contenant un mélange d'un gaz riche en oxygène et de gaz d'échappement recyclé en présence d'un système de catalyseur et d'un solvant liquide. Le traitement de gaz résiduaires est significativement simplifié car seule une petite quantité du gaz d'échappement est libérée dans l'atmosphère. Le procédé décrit par cette invention présente de grands avantages à la fois du point de vue économique et du point de vue environnemental.
