Experimental (liquid + liquid) equilibrium (LLE) data were obtained for the extraction of phosphoric acid from water by mixed-solvents (dichloromethane, 1,2-dichloroethane) at different ratios at T = 298.15 K and ambient pressure. The measured binodal curves and tie-line data for quaternary mixtures of (water + phosphoric acid + dichloromethane, 1,2-dichloroethane) are presented. The measured tie-line data have been correlated using the NRTL activity coefficient model to obtain the binary interaction parameters of these components. The NRTL model predicted the equilibrium compositions of the quaternary mixtures and the deviation which is not too low. The results show that the mixed-solvent (25% dichloromethane, 75% 1,2-dicholoroethane) has a higher separation factor than the other ratios of this mixed-solvent at the temperature studied.
