Title (EN) DEHYDRATION-HYDROLYSIS PROCESSES AND CATALYSTS THEREFOR
(FR) PROCÉDÉS DE DÉSHYDRATATION-HYDROLYSE ET LEURS CATALYSEURS
Abstract:
(EN) A process for the co-production of acetic acid and dimethyl ether by contacting methyl acetate and methanol in the presence of catalysts comprising crystalline zeolites having a FER framework type which crystallites have a dimension in the c-axis of about 500 nanometres (nm) or less and a ratio of the c-axis : b-axis dimension of 5:1 or greater and a method for preparation of the zeolites utilising piperazines.
(FR) L'invention concerne un procédé de co-prodution d'acide acétique et d'oxyde de diméthyle en mettant en contact de l'acétate de méthyle et du méthanol en présence de catalyseurs comprenant des zéolites cristallines ayant une ossature de type FER, lesdites cristallites ayant une dimension selon l'axe c d'environ 500 nanomètres (nm) ou moins et un rapport de dimension axe c:axe b de 5:1 ou plus. L'invention concerne également un procédé de préparation des zéolites en utilisant des pipérazines.
