Abstract
Process for the manufacture of methyl acetate by carbonylating a carbonylatable reactant selected from dimethyl ether and dimethyl carbonate containing less than 2.5 wt % water with carbon monoxide in the presence of a mordenite catalyst. The mordenite has been ion-exchanged with at least one Group IB metal, and the molar ratio of the Group IB metal to total aluminum present in the mordenite is in the range 5 to 50 mol %.
