Abstract

Abstract : Reversible production–separation systems can be prepared by varying the speciation of at least one of their components. Abstract : The ability to induce reversible transitions between homogeneous solutions and biphasic systems is of paramount relevance in separation processes. In this context, pH-triggered aqueous biphasic systems composed of ionic liquids and salts are here disclosed as switchable mono/biphasic systems, and their potential application is further demonstrated through an integrated approach comprising both the production and separation of hydroxymethylfurfural from fructose.
