以二甲基亚砜为溶剂分离多种共沸物系的研究

Study on the Separation of Multiple Azeotropes with Dimethyl Sulfoxide as Solvent

以丙酮-甲醇、醋酸甲酯-甲醇、四氢呋喃-乙醇、甲基叔丁基醚-甲醇4个常见共沸体系为研究对象,运用化工模拟软件Aspen Plus计算二甲基亚砜对相对挥发度数据和拟二元汽液平衡相图的影响,论述二甲基亚砜作为萃取精馏工艺的萃取剂的可行性。

In this paper,four azeotropic systems of acetone-methanol,methyl acetate-methanol,tetrahydrofuran-ethanol,and methyl tert-butyl ether-methanol were used as the research objects.Calculating the effect of dimethyl sulfoxide on relative volatility data and quasi-binary vapor-liquid equilibrium phase diagram using Aspen Plus,discusses the feasibility of using dimethyl sulfoxide as an extractant in the process of extractive distillation.
