ABSTRACT
The liquid-liquid equilibrium data of the two ternary systems of n-propyl acetate + n-propanol + 1-Butyl-3-methylimidazolium hydrogensulfate and isopropyl acetate + isopropanol + 1-Butyl-3-methylimidazolium hydrogensulfate were measured at 298.15 K, 318.15 K and under atmospheric pressure in this work. The extraction effect of ionic liquids was discussed by comparing the values of distribution coefficient and separation factor. The influence of temperature on the liquid-liquid equilibrium data was discussed. The binary interaction parameters of NRTL and UNIQUAC models were obtained by regressing the experimental data.
