Abstract
Consistent vapour¨Cliquid equilibrium data at 101.3 kPa have been determined for the ternary system dipropyl ether + 1-propyl alcohol + 2-ethoxyethanol and two constituent binary systems: dipropyl ether + 2-ethoxyethanol and 1-propyl alcohol + 2-ethoxyethanol. The dipropyl ether + 2-ethoxyethanol system shows positive deviations from ideal behaviour and 1-propyl alcohol + 2-ethoxyethanol system exhibits no deviation from ideal behaviour. The activity coefficients and the boiling points were correlated with their compositions by the Wilson, NRTL and UNIQUAC equations. It is shown that the models allow a very good prediction of the phase equilibria of the ternary system using the pertinent parameters of the binary systems. The parameters obtained from binary data were utilized to predict the phase behaviour of the ternary system. The results showed a good agreement with the experimental values. Moreover, the entrainer capabilities of 2-ethoxyethanol were compared with 1-pen

摘要：在常压下测定了三元体系（二丙醚 + 1－丙醇 + 2-乙氧基乙醇）和2种二元体系（1：二丙醚+ 2-乙氧基乙醇；2：1-丙醇 + 2-乙氧基乙醇）的连续性气液平衡数据。“二丙醚+2-乙氧基乙醇”体系与理想模型表现出正偏差而“1-丙醇+2-乙氧基乙醇”体系则无偏差。用Wilson方程、NRTL方程和UNIQUAC方程求得上述体系的活度系数和沸点分别与其成分相关。表明该模型可用二元体系有关参数对三元体系的相平衡做出恰当预测。来自二元体系的数据用于预测三元体系的相平衡。这些结果与实验价值是吻合的。而且，我们比较了2-乙氧基乙醇与1-戊醇、丙酸丁酯和N,N-二甲基甲酰胺的共溶能力，结果表明N,N-二甲基甲酰胺是最好的共溶剂。

1 前言
本实验是用不同共溶剂分离醇、醚混合物的热力学研究的一部分。筛选用于萃取性蒸馏的溶剂的目的是确定其是否为有前景的分离技术，如果有前景的话选用哪几种溶剂组成溶剂体系在分离方面最有选择性。选择性仅是优良溶剂必具特点之一，还要从下述因素的角度来评价，例如成本、稳定性、粘度和毒性。统筹考虑这些因素会不可避免地减少潜在溶剂的数量，并且也需要对实验数据进行更全面的评价。
当前的工作需要借鉴Sheibels 的溶剂选择标准[1] ，并采用分离因子算法。我们选择前人使用过的1-戊醇[2]、丙酸丁酯[3] 和N,N-二甲基甲酰胺[4]，我们给出了试验室和化工上常用的2-乙氧基乙醇(众所周知其商标名：赛珞素)获得的结果。
