To screen the proper solvent for separating prop-2-enoic acid aqueous solution by the method of extraction followed by heterogeneous azeotropic distillation, the liquid liquid equilibria (LLE) data for the ternary system water + prop-2-enoic acid + isobutyl ethanoate at (293.15, 303.15, and 313.15) K were measured at atmospheric pressure. The reliability of the experimental LLE data was ascertained through Othmer Tobias and Hand correlations. The LLE phase diagrams at different temperatures for the ternary system were given. Distribution coefficients and separation factors were calculated from the LLE data. The thermodynamic models of nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) were used to correlate the data of the ternay system. The calculated values from both models agree well with the experimental values.
