ABSTRACT
(Liquid + liquid) equilibrium (LLE) data for (water + propionic acid + dimethyl phthalate) were measured under atmospheric pressure and at T = (298.2, 303.2, 308.2 and 313.2) K. Phase diagrams were obtained by determining solubility and tie-line data. The LLE data of the ternary systems were predicted by UNIFAC method. Distribution coefficients and separation factors were evaluated over the immiscibility regions.
