ABSTRACT
Liquid liquid equilibria (LLE) data of one quaternary mixture for water + methanol + methylanthranilate (MA) + toluene and two constituent ternary mixtures for the systems (water + MA + toluene) and (water + methanol + toluene) at (298.15, 313.15, and 323.15) K were measured at atmospheric pressure. The reliability of the experimental LLE data was ascertained through Othmer Tobias and Bachman correlations. The LLE experimental data for the systems were correlated using the universal quasichemical (UNIQUAC) and nonrandom two-liquid (NRTL) models. The average root-mean-square deviations (RMSDs) of the NRTL and UNIQUAC models were 1.257 and 0.997. Both models accurately correlated the experimental tie-line data, while the correlation of the NRTL model was inferior to that of the UNIQUAC model.
