摘要: A process for preparing methyl acetate by the carbonylation of dimethyl ether with carbon monoxide in the presence of hydrogen and a zeolite catalyst wherein, in a first step the carbonylation is conducted with a carbon monoxide to hydrogen molar ratio of at least 1 and in a second and subsequent step, the carbonylation is conducted with a hydrogen to carbon monoxide molar ratio of greater than 1.
