The experimental binodal curves and tie lines were determined for cyclohexane-NaCl salt solution-pyridine systems at 25℃, and those tie line data were used to test thermodynamic consistency. The NaCl salt solutions were prepared with aqueous solution of 5%, 10% and 15% NaCl salts respectively.
The experimental tie line data were correlated with he UNIQUAC model, and the parameters and the calculated values of tie were predicted. The effect of salt addition on liquid-liquid equilibria was also studied along with the increment of salt concentration.
