由环氧乙烷与甲醇、三氟化硼乙醚进行加成反应，中和反应产物得甲氧基乙醇。再与苯酐进行酯化反应，然后用活性炭脱色、蒸馏、水洗、碱洗、脱水、压滤而得成品。酯化反应产物水洗后，进行减压蒸馏，这种后处理工艺也被工业生产采用。工业品DMEP的含量≥99。原料消耗定额：苯酐750kg/t、环氧乙烷820kg/t、甲醇660kg/t。 | |
主要用作乙酸纤维素的增塑剂，它的挥发性比邻苯二甲酸二乙酯小，可有很好的耐久性，同时使薄膜具有坚韧性。可用于漆包线、电影胶片、高强度清漆、胶粘剂和层压板胶粘剂等；也用作气相色谱固定液、三乙酸片基的增感剂和溶剂。可用作纤维素树脂、乙烯基树脂、合成橡胶的增塑剂，挥发性比邻苯二甲酸二乙酯(DEP)小，可赋予制品很好的耐久性，坚韧性，耐油性。主要用于醋酸纤维素的增塑剂，制造漆包线、电影胶片、高强度清漆、胶黏剂和层压板胶黏剂等。 |
