The ternary liquid-liquid equilibria (LLE) were analytically determined at 298.15 K for the following systems: {methyl tert-butyl ether (MTBE) + water + 1-ethyl-3-methylimidazolium-ethylsulfate (EMISE)}, {MTBE + water + 1-butyl-3-methylimidazolium-tetrafluoroborate ([Bmim][BF4])}, {ethyltert-butyl ether (ETBE) + water + EMISE}and {ETBE + water + [Bmim][BF4]}.All the determination were carried out at atmospheric pressure using stirred and thermo-regulated cells. The experimental data were correlated with the well-known NRTL and UNIQUAC activity coefficient models. In addition, distribution coefficients with selectivity of the ionic liquids EMISE and [Bmim][BF4] for water in the MTBE or ETBE phase were determined.
