| 摘 要： | 本文通过改型的UNIQUAC方程 ,利用NEWTON RAPHSON法计算了二元、三元及四元液液平衡数据。从中发现 ,当具有部分互溶性质组分的活度系数发生突变时 ,则该体系就会出现分层现象。为此 ,本文认为具有部分互溶组分活度系数的突变可做为多组元溶液分相的判据。

| Abstract: | In this paper, by calculation of the modified UNIQUAC equation, we have acquired the result of binary, ternary and quartery solution Liquid Liquid equilibrium data with Netwon Raphson method. When activity coefficient of some components with partly miscible solution have a increasation steeply, this solution will become two liquid phase. So the condition of phase separation for multicomponent solutions is that activity coefficient of some components have a increasation steeply at phase interface with partly miscible solution. |
