ABSTRACT
Liquid-liquid equilibrium (LLE) data were determined for two binary systems {diisopropyl ether (DIPE) + 1-ethyl-3-methylimidazolium ethylsulfate (EMISE)} and {DIPE + 1-butyl-3-methylimidazolium tetrafluoroborate([Bmim][BF4])}at temperatures between 293.15 K and 313.15 K. LLE data for six ternary systems {DIPE + water + EMISE} and {DIPE + water + [Bmim][BF4]} at 293.15 K, 303.15 K, and 313.15 K were also reported. Experiments were carried out at atmospheric pressure using stirred and thermoregulated cells. The experimental data were correlated with the well-known NRTL and UNIQUAC activity coefficient models. In addition, distribution coefficients and selectivities of the ionic liquids EMISE and [Bmim][BF4] for water in the DIPE phase were measured.
