本文用改进的Rose釜分别测定了在750mmHg压力下的丙酮-甲醇-NaI体系和700mmHg压力下的异丙醇-水-LiCl、CaCl_2、NH_4Cl、(CH_3)_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。
In this paper, the gas-liquid equilibrium data of acetone-methanol-NaI system under 750mmHg pressure and isopropanol-water-LiCl, CaCl_2, NH_4Cl and (CH_3) _4NCl systems under the pressure of 750mmHg were measured in a modified Rose kettle. When the composition of the two-liquid system is fixed, there is a linear relationship between the salt concentration and the boiling point, which is basically consistent with the linear relationship derived from the thermodynamics.
