Abstract
Process for the production of methyl acetate by carbonylating 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 275 to 350° C. and in the presence of hydrogen.
