摘　　要：介绍了以环氧乙烷、乙酸乙酯为原料,水滑石所衍生的镁铝复合氧化物作催化剂,一步合成乙二醇单乙醚醋酸酯的方法。对其反应条件进行优化,得到适宜的工艺条件:n(乙酸乙酯):n(环氧乙烷)=4:1,反应温度135℃,催化剂用量为环氧乙烷质量的4％,反应时间60min,体系初压0.9MPa,在此条件下乙二醇单乙醚醋酸酯收率为39.21％。A new process is reported to produce ethylene glycol menoether acetate which comprises reacting ethylene oxide and ethyl acetate by using oxid compound from hydrotolcite like compound. The optimum was obtained as follows: n(ethyl acetate): n(ethylene oxide) =4:1 condition reaction temperature 135℃, catalyst quantify = 4% of mass of ethylene oxide, reaction time 60 min and initial system pressure 0.9 MPa EGEEA yield of 39.21% was attained.
