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 CaCl2 is physical chemistry action.It related to the phenomena of salting-out and salting-in.

Key words: Formic acid-acetic acid-water-calcium chloride system, Vapour-liquid phase equilibrium, Salt effect
