Salt effect parameters(from Furlers equation)of 6 ethanol-water-1-1 type electrolytic (LiC 、LiBr、NaBr、NaAc、KCI、KI)systems were determined by isobaric VLE experi ments.A calculation method of these parameters at any nonelectrolytic concentration was pro- posed based on Pierottis scaled particle theory.The term of hard sphere interaction was calculated by Masterton-Lees equation.The term of soft sphere interaction was calculated by Hu Yings molecular thermodynamic model
in which the diameter of naked ion was replaced by solvated ion and solvation coefficient was taken to be a adjustable parameter.A correlation equation for the locallzed dielectrical constant of mixture and liquid concentration was obtained by mapping out experimental point.The calculated isobaric VLE salt effect parameters of 14 ethanol-water-1-1 type electrolytic systems were in good agreement with literature values and experimental values of this work within the wider range of Liquid concentration.
