PROBLEM TO BE SOLVED: To decompose methyl acetate into acetic acid and methanol in a high conversion and efficiency by hydrolyzing methyl acetate in the presence of a noble metal catalyst and hydrogen. SOLUTION: Methyl acetate is decomposed into acetic acid and methanol by hydrolyzing the compound preferably in the form of an aqueous solution having a concentration of 0.05-25wt.% at 80-200 deg.C, preferably 150-200 deg.C in the presence of a noble metal catalyst (e.g. Pt/C powder) consisting of a catalyst containing at least one kind of platinum group metal selected from Pt, Pd, Ir, Rh, Os and Ru and optionally supported on silica, activated carbon, etc., and in the copresence of hydrogen, preferably molecular hydrogen. The hydrolysis is preferably carried out by a fixed-bed liquidphase continuous reaction. |
