摘　　要：研究了乙醇与环氧丙烷(PO)在固体碱催化剂MAF存在下非均相合成丙二醇单乙醚的过程。在反应温度为120～130℃,w(催化剂)=0.5％～1.0％,乙醇与PO的摩尔比为(4～6):1的条件下,PO的转化率为98％,丙二醇单乙醚的选择性高于92％,收率达90％,产物中伯醚的选择性为92％～93％。催化剂使用后无需处理,可重复使用。The synthetic process of propylene glycol monoethyl ether from propylene oxide and ethanol using solid base catalyst MAF was investigated. Under the reaction conditions of reaction temperature 120-130℃,amount of catalyst 0.50%-1.0%, and ethanol/PO molar ratio= (4-6):1, the conversion of propylene oxide is about 98%, the selectivity and yield of propylene glycol monoethyl ether is >92% and 90% respectively, and the selectivity of primary ether is 92%-93% in the product. The catalyst could be reused directly for many times.
