CA 2760654

A process for the production of at least one carbonylation product selected from acetic acid and methyl acetate by carbonylating at least one carbonylatable reactant selected from methanol and reactive derivatives thereof with carbon monoxide in the presence of a catalyst which is a mordenite which has been treated with an aqueous ammonium hydroxide solution and has a silica : alumina molar ratio of at least 10 : 1.

L'invention porte sur un procédé pour la production d'au moins un produit de carbonylation choisi parmi l'acide acétique et l'acétate de méthyle, par carbonylation d'au moins un réactif apte à subir une carbonylation choisi parmi le méthanol et les dérivés réactifs associés avec du monoxyde de carbone, en présence d'un catalyseur qui est une mordénite qui a été traitée avec une solution aqueuse d'hydroxyde d'ammonium et qui présente un rapport molaire silice:alumine d'au moins 10:1.
