| 摘 要： | 本文采用Otsuki-Williams式汽液平衡釜测定了甲酸-乙酸-水体系及甲酸-乙酸-水-氯化钙体系在98658.28Pa下汽液平衡数据。氯化钙的加入量为0.5mol/(kg溶剂)。结合盐效应的作用情况,对相图进行了分析。研究结果表明:氯化钙的加入对体系起了物理化学作用,它与盐溶、盐析现象有关。

| Abstract: | Vapour-Liquid equilibrium was measured by Otsuki-Williams still at 98658.28Pa. Analyses were made of the 3-component system AcOH-HCO2H-H2O and the 4-component system AcOH-HCO2H-H2O-CaCl2 at the vapour-liquid equilibrium.CaCl2 was used 0.5 mol/(kg solv).The results show that the favorable effect of CaCl, is physical chemistry action.It related to the phenomena of salting-out and salting-in. |
