摘要

本文在Lenoir工作的基础上

重新推导了((?)γ/(?)χ)_(x=0)的数学表达式

结果与Kikic及Renon在1976年推导的公式不同.按本文推导的结果

用色谱测定了十个二元系的γ_1~∞_1与((?)lnγ_1/(?)x_1)x_1=0之值

代入UNIQUAC方程求取方程参数

再用求得的方程预测全浓度范围汽波平衡数据.除其中四个二元系无文献数据

另一个因形成氢键而误差较大外

均与文献数据甚为符合.

Abstract

On the basis of Lenoirs work

a new mathematical expression for x=0 has been derived

which is different from that of Kikic and Renno. Values of γ∞1 and for ten binary systems have been calcula- ted from GLC data according to the results derived in this work. When the experimental values of γ∞1 and were substituted into the UNIQUAC equation

the parameters were evaluted

and the vapor-liquid equilibria of these binary systems were predicted.
