Abstract

Abstract: Vapor pressures were measured by the static twin-ebulliometer method at five temperatures adjacent to the normal boiling point for solutions of calcium chloride in water, in methanol and in ethanol, and for solutions of potassium acetate in water and in ethanol. The cubic chain-of-rotators (CCOR)equation of state was used to correlate the experimental data. The average deviation of correlated results is ±0.42%. The parameters of the CCOR equation of state obtained can be used for calculating vapor-liquid equilibria for other salt-containing systems.

摘要： 用静态-双沸点仪比较法测定了不同温度下CaCl_2-H_2O,CaCl_2-CH_3OH,CaCl_2-C_2H_5OH,KAc-H_2O,KAc-C_2H_5OH五种溶液的蒸汽压,共132个数据点.以CCOR状态方程关联实验数据,相对平均误差为±0.42%.所得的状态方程参数可用于含盐溶液汽液平衡的计算.
