Abstract

Effects of LiCI, LiBr and CaCI2 on vapor-liquid equilibrium of isopropanol-water system were measured by the dynamic method at constant temperature and constant solvent composition. From these equilibrium data, the activity coefficients of isopropanol and water and the relative change of chemical potentials of both solvents by salt addition, Δμ, were exactly determined. Linearity of Δμ with respect to salt concentration assumed by Johnson and Furter was observed in low salt concentration region.
