本发明涉及合成醋酸烯丙酯催化剂的制备方法,主要解决现有醋酸烯丙酯催化剂的空时收率和选择性低的问题。本发明通过采用合成醋酸烯丙酯催化剂的制备方法,包括以下步骤:(a)将载体在浸渍溶解有含钯化合物和含铜化合物溶液中得到催化剂前体I;(b)用碱溶液处理催化剂前体I得到催化剂前体II;(c)将催化剂前体II浸渍含有稳定剂的溶液中得到催化剂前体III,所述稳定剂为聚乙烯基吡咯烷酮或聚丙烯酸碱金属盐或者两者的混合物;(d)用还原剂还 The invention relates to a preparation method of an allyl acetate catalyst, which mainly solves the problems of low yield and selectivity of the existing allyl acetate catalyst. The method comprises the following steps of: (a) obtaining a catalyst precursor I by impregnating a carrier with a solution containing a palladium-containing compound and a copper-containing compound; (b) treating the catalyst with an alkali solution Precursor I gives catalyst precursor II; (c) impregnating catalyst precursor Il with a solution containing a stabilizer to obtain a catalyst precursor III, the stabilizer is a mixture of polyvinylpyrrolidone or polyacrylic acid alkali metal salt, or both ; (d) also with a reducing agent
