(Liquid + liquid) equilibrium (LLE) data for the ternary systems of the (water + phosphoric acid + dichloromethane) and (water + phosphoric acid + 1,2-dichloroethane) systems at T = 298.2 K have been studied. The effect of inorganic salts (sodium chloride and calcium chloride) on the LLE data for these ternary systems has also been investigated. The NRTL and GMDH correlations are used to fit the tie line data of these ternary liquid systems. The results for the binary interaction parameters for the NRTL model have also been reported. In order to selecting a suitable salt for better separation, the distribution coefficients and the separation factors by adding the same percent of the salts (10 wt%) have been calculated and compared. The tie line data of the ternary systems were correlated using the Othmer-Tobias method. (C) 2013 Elsevier Ltd. All rights reserved.
