摘要：
Liquid-liquid equilibria (LLE) for the ternary system {hexane + benzene + 1-ethyl-3-methylimidazolium ethylsulfate ([emim]C(2)H(5)SO(4))} have been measured at the temperatures (298.2, 313.2 and 328.2) K and atmospheric pressure. The reliability of the experimental data was tested using the Othmer-Tobias correlation. For the extractive effectiveness of the solvent, the distribution ratio and separation factor curves were plotted and compared with those Of sulfolane. In addition, the LLE data were also correlated with UNIQUAC and NRTL models in a satisfactory manner. (C) 2009 Elsevier B.V. All Fights reserved.
