In this study, ternary liquid-liquid equilibrium of systems composed of 2-propanol, sodium salts, and water as 2-propanol + sulfate/nitrate/sodium acetate + water were successfully measured at 298.15 K and 101.3 kPa. The cloud-point method was used to determine the binodal curve of aqueous two-phase systems, formed by 2-propanol and an inorganic salt. According to this technique, it was found that the use of initial saline solutions at a maximum concentration provided more reliable results than with a salt solution with a minimum concentration. The binodal points obtained experimentally were adjusted by Mistry or Merchuk models. The Othmer-Tobias and Bancroft equations were used to evaluate that the tie line data were reliable. The strength of the salting-out effect of the different salts was evaluated by the effective excluded volume theory and the Setschenow-type equation. The Othmer-Tobias equation exhibited excellent results for sulfate systems, while the Setschenow-type equation showed the best values for nitrate and acetate. It was found that for 2-propanol + sodium salts + water systems, the power of the saline effect of the anions investigated followed the order of sulfate > nitrate > acetate. Two water-rich phases were observed in the sulfate systems, in spite of the nitrate and acetate systems, which had an extremely alcoholic phase and a salt-rich and a water-rich phase.
