Procedure

The catalyst (B) of the present invention shows a specific behavior that increasing a space velocity notably improves a selectivity of acetic acid and/or methyl acetate and can control the composition of a reaction product. That is, methyl formate and acetic acid or methyl acetate are formed at the space velocity of from 50 to 300 (g-cata.h mol-1). Methyl formate is scarcely formed at the space velocity of from 500 to 10,000 (g-cata.h mol-1), particularly 1000 or more (g-cata.h mol-1), and acetic acid and/or methyl acetate is formed at a selectivity as high as about 100%. Therefore, it enables to produce acetic acid or methyl acetate industrially at a good productivity using methanol as a sole raw material.
