A process for producing ethylidenediacetate which comprises reacting methyl acetate or dimethyl ether, carbon monoxide and hydrogen in the presence of catalyst comprising as a secondary-component at least one material selected from iodides and bromides and as a main component at least one material selected from nickel, nickel compounds, cobalt and cobalt compounds under substantially anhydrous conditions is disclosed. According to the present invention synthesis of ethylidenediacetate is achieved by using cheaper catalyst than the prior catalyst.
本发明公开了一种生产亚乙基二乙酸酯的工艺,该工艺包括在催化剂的存在下,使乙酸甲酯或二甲醚、一氧化碳和氢在基本上无水的条件下发生反应,催化剂包括作为辅助组分的至少一种选自碘化物和溴化物的材料,以及作为主要组分的至少一种选自镍、镍化合物、钴和钴化合物的材料。根据本发明,亚乙基二乙酸酯的合成可以使用比以前便宜的催化剂。
