Application of [EMim][ESO4] ionic liquid as solvent in the extraction of toluene from cycloalkanes: Study of liquid-liquid equilibria at TÂ =Â 298.15Â K

▶ [EMim][ESO4] was studied as solvent to extract toluene from cycloalkanes. ▶ Liquid-liquid equilibrium data were measured at 298.15 K and atmospheric pressure. ▶ Selectivity and solute distribution ratio were obtained and compared with literature. ▶ Experimental data were correlated using NRTL and UNIQUAC models. ▶ [EMim][ESO4] can be used as solvent for the studied liquid-liquid extraction.
