ABSTRACT
The liquid-liquid equilibrium (LLE) experiments for n-butanol + n-hexane + ethylene glycol were carried out and LLE data were measured at 298.15, 303.15, 308.15, 313.15 and 323.15 K under atmospheric pressure. The analysis results of the effects of n-butanol content and temperature on extraction showed that high n-butanol content was not favorable for extraction, and temperature had little effect on extraction. Moreover, the NRTL and UNIQUAC models were applied to correlate the LLE data, and the correlated data indicated that UNIQUAC model showed a better correlation performance.
