摘要
本文在正规溶液理论基础上，考虑了混合熵效应和长程静电作用，提出了可用于各种含水体系液液平衡计算的普遍方程，以及分子间作用参数与温度的关系式，关联了具有上会溶温度、下会溶温度和两者同时存在的有机物－水体系的液液平衡数据。该普遍方程可用于含水、有机物和（或）电解质的二元及三元体系液液平衡计算。
In this paper. based on the regular solution theory, a general equation for the calculation of different kinds of LLE systems containing water was developed. A mixing entropy term and a longrange electrostatic term were introduced. A relationship between the interaction parameter and the absolute temperature was proposed. It can be used to cortelate the LLE data for water-organic binary systems with upper and lower critical solubility temperatures. The general equation is applicable to the binary or ternary LLE systems containing water. organic compounds and/or electrolytes.
