Abstract

Procédé de purification d'un diméthyle naphtalène dicarboxylate produit à partir d'un acide dicarboxylique de naphtalène lequel à son tour est produit par l'oxydation en phase liquide d'un dialkylnaphtalène ou d'un dérivé partiellement oxydé de celui-ci, en présence d'un catalyseur comprenant un composant contenant du bromure, et au moins un composant contenant du cobalt ou du manganèse.
