ABSTRACT

Liquid-liquid equilibria (LLE) were determined for the ternary systems of ionic liquid + alkane (hexane, heptane or octane) + benzene at T = 298.15 K and atmospheric pressure. 1-Butyl 3-methylimidazolium nitrate [Bmim][NO3] or 1-methyl 3-octylimidazolium nitrate [Omim][NO3] were used as ionic liquid. The selectivities values for the ternary systems with [Bmim][NO3] are higher than [Omim][NO3]. The selectivities values show that [Bmim][NO3] is more suitable solvent for benzene extraction than [Omim][NO3]. The reliability of the LLE data was tested using Othmer Tobias and Hand equations. The experimental data was correlated using the NRTL thermodynamic model. The results show the NRTL model can correlate the experimental data with good accuracy.
