摘要

利用本文(I)报中提出的二元混合粘度与过量Gibbs活化自由能间的关联式

并以McAllister的多元体相互作用模型关联粘度数据

对九对二元系统(其中三对是含醇系统

一对是醇水系统)进行了从粘度数据推算汽液平衡数据.计算结果与相应的实验值比较

除一对系统的偏差较大外

其余八对的泡点均方根差为0.09—0.80℃

汽相组成均方根差为0.003—0.038.

Abstract

By employing the equation relating the viscosity of a binary mixture to its excess Gibbs free energy as proposed in part ( I ) of this series of papers

and by correlating viscosity data with McAillisters multi-bodg interaction model

calculation of vapor-liquid equilibrium data has been made for 9 binary systems

among which 3 are alcoholic organic ones and 1 is alcoholic aqueous. Calculated values are compared with corresponding experimental data. Except for one system showing relatively high deviation

the root mean square deviations of the bubble points and the vapor phase compositions of all systems are 0.09-0.80℃ and 0.003-0.038respectively.
