Carbonylation process for the production of acetic acid and/or methyl acetate

摘要

Process for the manufacture of at least one of acetic acid and methyl acetate by carbonylating at least one carbonylatable reactant selected from methanol, dimethyl ether and dimethyl carbonate with carbon monoxide in the presence of a zeolite of structure type MOR. The zeolite has greater than 50% of its crystals in the size range to 3 microns.
