本文用改进的Rose分别测定了在750mmHg压力下的丙酮-甲醇-NaI体系和700mmHg压力下的异丙醇-水-LiCl, CaCl2, NH4Cl, (CH3)4NCl体系的气液平衡数据。当双液系组成固定时, 盐的浓度与沸点之间存在线性关系, 与热力学导出的线性关系基本相符。

The isobaric vapor liquid equilibrium data of salt-contg. acetone-methanol and isopropanol-water systems were determine by using an improved Rose still. A linear relationship was found between the boiling temperature and the mole fraction of salt present, when the binary composition is fixed. The calculated data are approx. in accord with the experimental values.-
