本发明涉及一种醋酸甲酯羰基化合成双醋酸亚乙酯的合成方法,主要解决现有技术中采用有机氮或者有机磷作促进剂,醋酸甲酯羰基化合成双醋酸亚乙酯反应醋酸甲酯的转化率低、双醋酸亚乙酯的产率低和选择性不高的问题。本方法以醋酸甲酯、一氧化碳和氢气为原料,溶剂为醋酸,在反应温度为 The invention relates to a method for synthesizing ethyl acetate by the carbonylation of methyl acetate, which mainly solves the problem that in the prior art, organic nitrogen or organic phosphorus is used as a promoter, and carbonylacetate is carbonized to synthesize ethylene diacetate. The conversion rate of ester is low, the yield of ethylene diacetate is low, and the selectivity is not high. The method takes methyl acetate, carbon monoxide and hydrogen as raw materials, the solvent is acetic acid, and the reaction temperature is
