摘　　要：以乳酸乙酯脱水反应为模型反应,分别考察了ZSM-5和丝光沸石分子筛的催化性能。结果表明最优的反应条件为温度180℃、反应时间3 h、催化剂用量10%。优化条件下乳酸乙酯转化率达到82.58%,丙烯酸乙酯的选择性达到37.38%。The conversion of ethyl lactate to ethyl acrylate with ZSM-5 or mordenite as the catalysts is investigated.Results show that the following reaction conditions is optimal:180℃,3 hours of reaction time and 10%(w/w) of catalyst amount.Under the optimal reaction conditions the conversion rate of ethyl lactate can be 82.58%,and the selectivity of ethyl acrylate,37.38%.
