摘要： PROBLEM TO BE SOLVED: To obtain methyl acetate in a high yield in a high selectivity stably for a long time by using a zeolite catalyst and reacting methanol with acetic acid in a vapor phase. SOLUTION: (B) Methanol is catalytically reacted with (C) acetic acid in the presence of (A) a zeolite catalyst in a vapor phase to give methyl acetate. The component A has the ratio of SiO2/Al2O3 of preferably >=10 and HZSM-5 or H type mordenite is preferable as a zeolite having an especially long life. Preferably the component A is used as a fixed bed catalyst or a fluidized bed catalyst for a flow reactor. The reaction is preferably carried out in the molar ratio of the component B/the component C of 1-3. A high methanol conversion is obtained by making acetic acid excessive in this method and the amount of unreacted methanol is small. Consequently obtained methyl acetate is readily separated.
