Abstract

Procédé permettant l'élimination et la récupération ultérieure du cuivre du catalyseur. Il consiste à faire passer un gaz renfermant de l'oxygène à travers une solution réactionnelle d'un phénol et du catalyseur complexe et à terminer la réaction et à séparer le composant cuivre de ce catalyseur par mise en contact de la solution réactionnelle avec un agent de chélation constitué d'un amino-acide afin de former un complexe chélaté de cuivre et de cet agent de chélation, et enfin à séparer et à mettre en contact ce complexe chélaté avec un sucre réducteur dans un milieu alcalin pour faire précipiter le cuivre sous la forme d'un oxyde. Application à la fabrication du poly(oxydiméthyl-2,6 phénylène-1,4).
