Abstract

L'INVENTION A POUR OBJET UN NOUVEAU CATALYSEUR. CE CATALYSEUR COMPREND A L'ETAT D'OXYDES DU CUIVRE, DU ZIRCONIUM ET UN METAL ALCALIN ET IL EST UTILISE POUR L'OXYDATION CATALYTIQUE AU MOYEN D'OXYGENE D'ACIDES CARBOXYLIQUES AROMATIQUES EN PHENOLS CORRESPONDANTS, PAR EXEMPLE POUR LA PRODUCTION DE PHENOL A PARTIR D'ACIDE BENZOIQUE OU DE CRESOLS A PARTIR D'ACIDES TOLUIQUES. IL OFFRE LES AVANTAGES D'UNE MEILLEURE SELECTIVITE ET D'UNE CONVERSION PLUS ECONOMIQUE DES ACIDES CARBOXYLIQUES EN PHENOLS.THE OBJECT OF THE INVENTION A NEW CATALYST. THIS CATALYST CONSISTS OF OXIDE STATE OF COPPER, ZIRCONIUM AND AN ALKALINE METAL AND IT IS USED FOR CATALYTIC OXIDATION BY MEANS OF OXYGEN OF AROMATIC CARBOXYLIC ACIDS IN CORRESPONDING PHENOLS, FOR EXAMPLE PHENOLIC PRODUCTION FROM BENZOIC ACID OR FROM CRESOLS FROM TOLUIC ACIDS. IT OFFERS THE ADVANTAGES OF BETTER SELECTIVITY AND A MORE ECONOMICAL CONVERSION OF CARBOXYLIC ACIDS INTO PHENOLS.
