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.
