ABSTRACT
This research focused on a study of the ionic liquid 4-methyl-N-butylpyridinium tetrafluoroborate ([mebupy]- BF4) as a solvent in liquid-liquid extraction. Liquid-liquid equilibrium data were obtained for mixtures of 4-methyl-N-butylpyridinium tetrafluoroborate + (benzene or ethylbenzene or m-xylene) + (N-hexane or N-octane) at T ) (313.2 and 348.2) K and T ) (313.2 and 333.2) K for the ternary mixture with benzene and p ) 0.1 MPa. The experimental data for the binary and ternary systems were well-correlated with the NRTL model. The aromatic/ aliphatic selectivity values were comparable to those of toluene + N-heptane. The ionic liquid [mebupy]BF4 is therefore a suitable solvent for an industrial extraction process for the separation of aromatic and aliphatic hydrocarbons.
