Salt effects on the solubilities of benzene, toluene, ethylbenzene, and propylbenzene were studied by making use of the solute vapor. The salting coefficients were determined at 25 °C, and the results were compared with the literature values and with those estimated by means of theoretical equations. The McDevit-Long equation did not give satisfactory predictions until the equation was multiplied by a factor of 0.4. The scaled particle theory gave a favorable agreement with the observations in most cases if suitable pair-potential parameters of solutes were used in the calculations.
