摘要

本工作改进了预饱和器结构

采用二级预饱和装置

用色谱测定了52组二元系在不同温度下88个无限稀活度系数

其中14个和文献报道的温度相近

数值与文献报道吻台.以乙苯为固定液的体系

其lnγ~∞与温度的倒数呈良好的线性关系

由此求出了相应的无限稀释溶解热.

Abstract

In this work

tne authors modified the structure of presaturators and determined 88 activity coefficients at infinite dilution of 52 binary systems at various temperatures by gas chromatography with double saturators. Data for 14 among these 88 were found to conform pretty well with those disclosed in literature. For systems containing ethylbenzene

the results indicated that good linear relation between In γ1∞ and the reciprocal of temperature was obtained and the heats of solution at infinite dilution of these systems were evaluated.
