摘要：Liquid-liquid equilibrium (LLE) and solubility data for the quaternary system isopropyl acetate + isopropanol + acetic acid + water and for the ternary systems isopropyl acetate + isopropanol + water and isopropyl acetate + acetic acid + water were studied at 313.15 K under 101.3 kPa. Five quaternary systems with different mole ratios of acetic acid to isopropanol were studied. The Othmer-Tobias and Bachman methods were used to correlate the tie-line data. The experimental LLE data were regressed by the NRTL thermodynamic model, indicating the experimental and the calculated data have a good correlation, with a standard deviation less than 1.42%.
