Abstract: The gas-liquid chromatographic method was used to measure the activity coefficients at infinite dilution (γ_1~∞) of some nonelectrolyte solutes in salt containing solutions of propylene carbonate at 333.2 K. For examining the relationship between lgγ_1~∞ and salt concentrations, the salt effect coefficients of solutes were calculated, and the interactions of solute with salt were disscused. Furthermore, the equilibrium constant of complex interaction between chloroform with anions has been obtained.
