摘要

本文论述了应用“分子聚集理论”对含羧酸体系的汽相进行非理想性校正的计算方法.在低压下

含羧酸体系的汽相由于缔合从而引起组分的汽相逸度系数偏离1较大

故对汽相非理想性的校正是不容忽视的.汽相应用“分子聚集理论”改进的维里方程而液相采用UNIQUAC活度系数方程对含羧酸体系的汽液平衡进行计算

取得较好的结果.

Abstract

In this paper

the calculating method which corrects the non-ideality of the vapor phase for systems containing carboxylic acid by the theory of molecular aggregation is proposed. The fugacity coefficient of the vapor phase for the components of these systems deviates seriously from unity owing to association. A modified virial equation is used for the vapor phase and UNIQUAC model is used for the liquid phase. Good results of calculation of vapor-liquid equilibrium data are obtained.
