Abstract: Vapor-liquid equilibrium data (VLE) were measured by usingotsudki-willlams still at 9.866×104 (Pa) for the 3-component system AcOH-HCO2H-H2O and the 4-component system ACOH-HCO2H-H2O-CaCl2 in the VLE,CaCl used was 0.5 (mol/kg solv.).The results show that the favorable effect of CaCl2 is physical chemistry action,which relates to the phenomena of salting-out and salting-in.
