ABSTRACT

Extraction of toluene from alkane (hexane, heptane or octane) was studied with the ionic liquid 1-butyl3-methylimidazolium nitrate ([Bmim][NO3]) or 1-methyl 3-octylimidazolium nitrate ([Omim][NO3])at 298.15 K and atmospheric pressure. The liquid-liquid equilibrium (LLE) data for ternary systems oftoluene + alkane + ionic liquid were measured and the selectivity values were calculated. The consistency of the experimental data was examined, using the Othmer-Tobias and Hand equations. The selectivity values for the ternary systems with [Bmim][NO3] is more than [Omim][NO3]. The experimental data werecorrelated with the NRTL thermodynamic model.
