In this paper, (liquid + liquid) equilibrium (LLE) data for the ternary systems (cyclohexane, or cyclooctane, or methylcyclohexane + ethylbenzene + 1-ethyl-3-methylimidazolium ethylsulfate) have been determined experimentally at T = 298.15 K and atmospheric pressure. The solubility curves and the tie-line compositions of the conjugate phases were obtained by means of density. The degree of consistency of the tie-lines was tested using the Othmer–Tobias equation, and the Non-Random Two-Liquid (NRTL) and the Universal Quasi-Chemical (UNIQUAC) models were used to correlate the phase equilibrium in the systems. Selectivity and solute distribution ratio were evaluated for the immiscible region.
Research highlights
► [EMim][ESO4] was studied as solvent to extract ethylbenzene from cycloalkanes.
► (Liquid + liquid) equilibrium data were measured at 298.15K and atmospheric pressure.
► Selectivity and solute distribution ratio were obtained and compared with literature.
► Experimental data were satisfactorily correlated using NRTL and UNIQUAC models.
► [EMim][ESO4] can be used as solvent for the studied (liquid + liquid) extraction.
