摘　　要：实验以乙酸乙酯-乙醇共沸体系分离为研究内容，以N、N一二甲基甲酰胺（DMF）作萃取剂，进行萃取精馏操作。探讨回流比和萃取荆加入速率对产品纯度和收率等的影响。得出在实验条件下适宜回流比为3，萃取剂加入速率为7-8ml／min的结论。The experiment consider ethyl acetate-ethanol azeotrope as research object, and N, N-dimethyl formamide （DMF） as extractant. We evaluated the effect of operating parameters such as reflux ratio and adding rate of extractant on the column performance. The effects of oper- ation parameters such as solvent ratio, reflux ratio and adding rate of extractant on product purity and recovery ratio were also studied. In con- clusion the optimal reflux ratio were 3 ,flow rate of solvent were 7-Sml/min respectively.
