ABSTRACT

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 acetic acid to isopropanol ratios were studied. The Othmer-Tobias and Bachman methods were used to correlate the tie-line data. The LLE data were regressed by NRTL thermodynamic model, indicating the experimental data and the calculated ones have a good correlation with the standard deviation less than 1.42%.
