摘要
针对工业上醋酸乙酯生产过程中提纯困难，导致生产能耗高的现状，研究了促进剂在提纯、分离醋酸乙酯中的应用。结果发现，促进剂能在常温下改变醋酸乙酯－乙醇－水之间的互溶度，达到脱水、提纯酯的目的。还进一步研究了其最佳的工艺参数及应用到工业生产中的可行性。结果表明，这一新的分离方法在工业上的应用是可行的。通过热量衡算得出，本分离方法比传统的方法可节能４０％。
To reduce energy consumption of purifying ethyl acetate,we investigate the possibility of applying promoters in purification of ethyl acetate.It is found that the promoter can change the mutual solubility of ethyl acetate ethanol water and purify ethyl acetate.The feasibility in the industry production is studied and the optimum operation parameter is further decided.This new separating method is proved feasible and can save 40% energy by comparing to the traditional method.
