ABSTRACT:
Disclosed is a carbonylation process for the manufacture of acetic anhydride wherein the utilization of carbon monoxide is increased. The process involves the liquid phase manufacture of acetic anhydride by contacting a mixture of (i) a reactant compound selected from methyl acetate, dimethyl ether or a mixture thereof, (ii) methyl iodide, (iii) catalyst components comprising rhodium and one or more promoters, and (iv) dissolved carbon monoxide in a carbonylation zone in which carbon monoxide is not fed below the surface of the mixture in a manner to increase the concentration of carbon monoxide in the liquid reaction mixture.
