ABSTRACT
The ternary liquid liquid equilibrium (LLE) experimental data for the system isopropyl acetate + ethanol + water have been measured at (293.15, 313.15, 333.15) K under pressure of 101.3 kPa in this work. The quality of the determined experimental data was checked by the Bachman and Hand equations, which the correlation coefficients of the Bachman equation were 0.9964, 0.9997, and 0.9994, and the those of the Hand equation were 0.9717, 0.9846, and 0.9934 for (293.15, 313.15 and 333.15) K. Moreover, the measured data were correlated by the nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) activity coefficient equations, and the parameters of the two equations were regressed. The comparison between the correlated values and the measured data was made, which the correlated values agree well with the determined LLE data. Meanwhile, the selectivity (S) and distribution coefficient (D) for this ternary system were calculated from the experimental data.
