Aqueous biphasic systems composed of ionic liquids and acetate-based salts: phase diagrams, densities and viscosities.

ABSTRACT: Ionic-liquid-based aqueous biphasic systems (IL-based ABS) have been largely investigated as promising extraction and purification routes. In this context, the determination of their phase diagrams and the physical properties of the coexisting phases are of high relevance when envisaging their large-scale applications. Low viscosities improve the mass transfer and reduce energy consumptions, while the knowledge on their densities is important for the equipment design. In this work, novel phase diagrams for aqueous solutions of imidazolium-based ILs combined with acetate-based salts, namely KCH₃CO₂ or NaCH₃CO₂, are reported and discussed. The ability of the acetate-based salts to induce the phase separation not only depends on the ions hydration e
