Abstract
Process for the production of methyl acetate by the carbonylation of a dimethyl ether feed with carbon monoxide under substantially anhydrous conditions, in the presence of a zeolite catalyst effective for the carbonylation. The carbonylation is carried out at a temperature in the range of greater than 250° C. to 350° C. and at a pressure in the range of greater than 10 barg to 100 barg.
