摘　　要：在常规的间歇萃取精馏实验装置中,研究了以N,N-二甲基酰胺(DMF)和二甲亚砜(DMSO)作萃取剂;在间歇萃取精馏塔中分离乙醇-乙酸乙酯体系的过程。对全回流时间、不同萃取剂、恒沸物组成、溶剂和混合物的体积比、加盐及加碱等因素考察,分析萃取精馏分离乙醇-乙酸乙酯共沸体系的影响,从而得出最佳的萃取条件。In the conventional batch extractive distillation experimental device, the batch extractive distillation process of ethanol- ethyl acetate system by using N,N-dimethy formamide and dimethy sulphoxide as extracting agents was studied. Effects of total reflux time, extractant, azeotrope composition, volume ratio of solvent to mixture ,adding salt, adding alkali and other factors on the extractive distillation separation of ethanol- ethyl acetate system were investigated, then the best extractive distillation conditions were obtained .
