Title
(EN) SYNTHESIS OF BISPHENOLS
(FR) SYNTHESE DE BISPHENOLS
Abstract
(EN)
The present invention is directed to processes and catalysts for the preparation of bisphenols. A preferred bisphenol is bisphenol A. The catalysts of the present invention comprise a metal oxide modified with an oxyanion. Examples of suitable catalysts according to the present invention include Group IVB metal oxides modified with Group VIB oxyanions.
(FR)
La présente invention concerne des procédés et des catalyseurs utiles pour la préparation de bisphénols. Le bisphénol A est un bisphénol préféré. Les catalyseurs de la présente invention comportent un oxyde métallique modifié à l'aide d'un oxyanion. Des catalyseurs appropriés selon la présente invention sont par exemple des oxydes métalliques du groupe IVB modifiés à l'aide d'oxyanions du groupe VIB.
