ABSTRACT
The ternary liquid liquid phase equilibria was investigated at 298.15K for hydrophilic alcohols (2-propanol/1-propanol)+ different salts of chloride (KCl/NaCl/CaCl2)+ water systems. The phase-forming and salting-out capability of the mentioned salts were discussed by both exclude effective volume and salting-out coefficient. The results showed that the salting-out capability of the studied salts are as follows: CaCl2 greater than NaCl greater than KCl. The phase-forming capability of the investigated hydrophilic alcohols was discussed by using the dielectric constant and the boiling point of the alcohols. The four-parameter equation was used to fit the binodal curves data and also the Bancroft and Othmer Tobias equations were successfully used to correlate of the tielines data. Correlation of the data demonstrates that the calculated method and experimental data are in good accord.
