Ethanol extraction from its azeotropic mixture with hexane employing different ionic liquids as solvents

► Several ionic liquids were investigated as solvents to extract ethanol from hexane. ► Determination of LLE for the ternary systems was carried out at T = 298.15 K. ► Structural influence of the ionic liquids on the extraction process was analyzed. ► Experimental LLE data were correlated by means of the NRTL and UNIQUAC models.
