The invention relates to a method for synthesizing vinyl acetate. When vinyl acetate is prepared from methyl acetate through the route of carbonylation and cracking, vinyl acetate yield and selectivity are low. The invention mainly aims at solving the problems. The vinyl acetate synthesis method comprises the following steps: methyl acetate carbonylation is carried out, such that ethylene diacetate is obtained; and ethylene diacetate is cracked, such that vinyl acetate is obtained. A carbonylation catalyst adopts SiO2, Al2O3 or a mixture thereof as a carrier, and has active components comprising at least one selected from iron-series elements, alkaline earth metal and at least one metal element selected from IB and VA. With the technical scheme, the technical problem is well solved. The method can be used in industrial production of vinyl acetate.
