含电解质体系的相平衡研究——用溶剂化方法关联含盐体系的汽液平衡

The Study of Phase Equilibrium of Electrolyte-Containing System——Correlation of VLE of Salt-Containing System by the Solvation Method

本文考虑到在混合溶剂的盐溶液中,各溶剂在盐组分周围产生不同的溶剂化作用,建立了一个非优先溶剂化模型.将此模型和NRTL模型或MH-81型状态方程相结合,关联了四十多个含盐体系的汽液平衡,计算结果和实验值吻合很好.

In the multi-solvent salt-containing solutions, there are different solva-tion effects surrounding salt ions for different solvation effects surrounding salt ions for different solvents. The present work combine a model of solvation for the solvents around the salt with activity coefficient correlation or MH-81 equation of state to correlate vapor liquid equilibria of more than forty salt-containing systems. The calculated valuer were in good agreement with the experimental data.
