1. A process for the production of methyl acetate by carbonylation of dimethyl ether which process comprises contacting in a reactor dimethyl ether with carbon monoxide in the presence of a zeolite catalyst, hydrogen, and at least one compound containing a hydroxyl functional group at a temperature of from 250 to 350° C. and at a molar ratio of hydrogen to carbon monoxide of at least 1,
wherein the process comprises introducing into the reactor the at least one compound containing a hydroxyl functional group, and the process is carried out in the absence of added methyl acetate;
wherein the at least one compound containing a hydroxyl functional group is one or more hydroxyl compound(s) selected from water, C1-C4 aliphatic alcohols, and C1-C4 aliphatic carboxylic acids; and
wherein the zeolite is a templated zeolite.
