Ionic liquids (ILs) have sparked interest in many fields of research as possible replacement solvents for organic diluents because of their near infinite tunability and unique chemical and physical properties. It is only recently that their unique ionic interactions have begun to be explored with the intent to extend our chemical understanding of ionic interactions in general. Since ILs are designed to have weak intramolecular interactions, to suppress the crystallization, they can also be exploited to advance our understanding of solvation.

520 $a Ionic liquids (ILs) have sparked interest in many fields of research as possible replacement solvents for organic diluents because of their near infinite tunability and unique chemical and physical properties. It is only recently that their unique ionic interactions have begun to be explored with the intent to extend our chemical understanding of ionic interactions in general. Since ILs are designed to have weak intramolecular interactions, to suppress the crystallization, they can also be exploited to advance our understanding of solvation.
520 $a Here, ILs have been explored not as a neoteric media, but as a phase modifier to produce chemically interesting systems which can be used to understand complicated phenomena of solvation. A kosmotropic salt will increase the dynamic structure of H2O and can "salt-out" hydrophilic ILs, due to their chaotropicity, yielding a salt/salt aqueous biphasic system. The chaotropic nature of 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) was confirmed through comparing the melting characteristics of [C4mim]Cl/aqueous solutions with aqueous solutions of a known kosmotropic salt, K3PO 4. ILs' weak intramolecular interactions cause very weak ion association in strong solvating solvents, like H2O, proven here in aqueous solutions of [C4mim]Cl.
520 $a Practical application of the salt/salt aqueous biphasic systems has been explored in the preferential partitioning of highly chaotropic ions, such as TcO4-, form kosmotropic solutions. Nonetheless, such applications require new synthetic methodologies for the IL community to move forward with any research into the fundamental properties of ILs. IL purity must be addressed, as halide contaminates can greatly affect the property sets of neat ILs. Additionally, the development of a synthetic methodology for a new carbonate-based imidazolium salt will allow for further studies on ion-pure ILs. A stable intermediate, 1,3-dimethylimidazolium hydrogen carbonate, was made possible through the manipulation of the chemical properties of H2O and CO2, and can be used in a clean metathesis via an acid-base reaction to many diverse halide-free ILs.
