PROBLEM TO BE SOLVED: To provide a method for producing vinyl acetate in high activity and high selectivity by using a catalyst having a space time yield higher than that of a conventional one, a low selectivity of carbon dioxide and a long life. SOLUTION: The objective vinyl acetate is obtained by reacting (B) ethylene with (C) oxygen and (D) acetic acid containing 10-90mol% water in the presence of (A) a catalyst containing (i) metal palladium, (ii) an alkali metal acetate, preferably potassium acetate, (iii) at least one kind of element selected from the group II in the periodic table, preferably copper or gold, (iv) at least one element selected from lead, tin, germanium, bismuth, antimony, arsenic, phosphorus, tellurium, selenium and sulfur, preferably the bismuth, the selenium and the tellurium in the method for producing the vinyl acetate. Moreover, the reaction is preferably performed under the condition within the range of 100-250 deg.C and 0-30kg/cm<2> G. |
