An ebulliometer was used to measure the vapor-liquid equilibrium at 101.3 kPa for four binary systems: (1) the acetone-water-CaCl2 system; (2) the 2-propanol-water-potassium acetate system and the 2-propanol-water-KBr system at different salt concentrations; (3) the ethyl acetate-ethanol system saturated with CaCl2; and (4) the acetone-carbon tetrachloride system saturated with CaCl2. The experimental results agree with the common behavior of salt effects on the phase equilibrium. An anomalous crossover between "salting out" and "salting in" effects on acetone had been observed for the acetone-carbon tetrachloride system saturated with CaCl2.
