Vapor pressures were measured by the static-twin ebulliometric 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 with 132 experiment points.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 salt-containing systems.
