ABSTRACT

Liquid-liquid equilibrium (LLE) data for ternary system (n-hexane + ethyl acetate + acetonitrile) have been measured at 298.15, 308.15 and 318.15 K under atmosphere pressure. NRTL and UNIQUAC models were used to correlate the LLE data and their model parameters were obtained. The fitting root-meansquare deviations (RMSD) of NRTL and UNIQUAC models were both below 0.17%, which demonstrated the successful correlations for the ternary LLE experimental data. Moreover, NRTL model gave slightly better predict results than UNIQUAC. Simultaneously, distribution coefficient (K) and separation factor (S) were calculated from the LLE data. Results showed that the extraction of ethyl acetate from n-hexane with acetonitrile as solvent was feasible.
