Salt effect on vapor-liquid equilibrium for the ethanol + water system was measured at 298.15 K using an experimental apparatus based on the static method. The salting-out effect of CaCl2, NH4I and NaI on the ethanol + water system follows the order of CaCl2 > NaI > NH4I. The observed experimental data were correlated by the use of a semiempirical model proposed by Hala (1983) with an accuracy of +/- 2.13%. The application of Hala’s model was confirmed in the ethanol + water system to be added the salts other than CaCl2 at 298.15 K.
