The invention relates to a vinyl acetate preparation method which is mainly used for solving the problems of space time yield and low selectivity of the prior art. The method for preparing allyl acetate is adopted, reaction raw materials which consist of ethylene, acetic acid, oxygen and water are contacted with a catalyst so as to obtain a reaction product containing allyl acetate, wherein the catalyst takes SiO2, Al2O3 or a mixture thereof as a carrier, and load active components comprise metal palladium, metal gold and alkali metal acetate; and the catalyst comprises 1-12g/L of palladium, 0.1-9g/L of gold and 10-90g/L of alkali metal acetate. The method is characterized in that the average crystal grain diameters of palladium and gold are between 4 and 9nm, and crystal grains with the average crystal grain diameters within a scope of plus or minus 20% account for 60-81% of the whole crystal grains. The method can be utilized for better solving the problems and used for allyl acetate industrial production.
