ABSTRACT
Liquid-liquid equilibrium (LLE) data for the ternary systems hexane + toluene + 1-ethyl-3-methylpyridinium ethylsulfate and hexane + ethylbenzene + 1-ethyl-3-methylpyridinium ethylsulfate were measured at T = 298.15 K and atmospheric pressure. Selectivity and solute distribution ratio, derived from the equilibrium data, were used to determine if this ionic liquid can be used as a potential extracting solvent for the separation of aromatic compounds from hexane. The consistency of tie-line data was ascertained by applying the Othmer-Tobias and Hand equations. The experimental data for the ternary systems were well correlated with the nonrandom two-liquid (NRTL) equation. The results were compared to those previously published for the separation of benzene from hexane using the same ionic liquid, therefore analyzing the influence of the radical in the benzene ring.
