Abstract
PURPOSE: In the presence of a rhodium catalyst and a halogen compound, an acetylacetonate or alkoxide of a specific kind of metal is used to effect the reaction between methyl acetate and carbon monoxide, thus producing acetic anhydride under a relatively low pressure in high selectivity.
CONSTITUTION: When acetic anhydride is produced by reaction between methyl acetate and carbon monoxide in liquid phase in the presence of a rhodium catalyst and a halogen compound such as methyl iodide, an acetylacetonate or alkoxide of a metal selected from the group consisting of Ti, V, Al, Th and Cr is added to the reaction system, preferably by 1W2mmol/l.
