ABSTRACT

Three ternary liquid systems, {dodecane + butylbenzene + [bmim]PF6, [hmim]PF6, or [omim]PF6}, were studied at 313 K and 333 K and atmospheric pressure. Equilibrium tie-line data were measured and plotted for all systems. The effects of the alkyl group in 1-alkyl-3-methylimidazolium hexafluorophosphate, temperature, and solvent-to-feed ratio upon solubility, selectivity (S), and distribution coefficient (K) were investigated. The liquid liquid equilibrium (LLE) data were correlated sufficiently with both universal quasichemical activity coefficient (UNIQUAC) and nonrandom two-liquid (NRTL) models, and the interaction parameters between each of the three pairs of components for the UNIQUAC and the NRTL models were estimated as a function of temperature. The root-mean-square deviations between the correlated results and experimental data were calculated and found to be satisfactory.
