摘要: 提出了液体混合的通用Gibbs自由能模型,据此建立了液液平衡的双节线、旋节线和临界点方程.这些方程不仅适用于小分子液体混合物,而且亦适用于高分子溶液.计算结果表明,它们能满意地描述各种类型的液液平衡及其会溶现象.

Abstract: On the basis of the generalized Gibbs free energy model for mixing of liquids proposed by this work, the equations of binodal, spinodal and critical point for LLE are established, which are applicable not only to liquid mixtures of small molecules, but also to polymer solutions. The results of calculation show that they can be satisfactorily used to describe a variety of LLE and consolute phenomena.
