摘要

Abstract

Ionic liquids have received increasing attention for their potential uses as non-volatile separation and reaction solvents

and the liquid-liquid equilibrium（LLE）of ionic liquid containing systems is of great importance for such practical applications.The NRTL(non-random two liquid)equation was extended and used in this paper for the calculation of the LLE data of some ionic liquid-alcohol binary systems.It was found that the extended NRTL model could be accurately used to represent the LLE of these ionic liquid-alcohol systems with the average absolute deviations lower than 0.6%.The LLE data of two ternary systems

H2O-n-butanol-［bmim］PF6 and H2O-n-butanol-［omim］PF6

were further successfully predicted for the first time by using the NRTL binary parameters.
