Liquid-liquid equilibrium determination and thermodynamics modeling for extraction of isopropanol from its aqueous solution

To separate isopropanol from its aqueous solution, isobutyl acetate, butyl acetate and butyl propionate were adopted as the extractive solvents, and the liquid-liquid equilibrium (LLE) data for the ternary systems (isobutyl acetate / butyl acetate / butyl propionate) + isopropanol + water were determined at 298.15 K and 308.15 K under atmospheric pressure. The experimental LLE data were correlated by the NRTL and UNIQUAC models, and the values...
