Hydrophilicity, the major determining factor influencing the solvation environment of protic ionic liquids.

The study of solubility of 4-nitroaniline and its N,N-diethyl derivative in ionic liquids (ILs) of varying water content has shown that it is the interaction between water and the ILs' ions, and not with the solute, that is the most important factor determining the solute's preferential hydration parameter and thus the solvation shell structure.

Unexpected preferential dehydration of artemisinin in ionic liquids.

Thermodynamic measurements (at 298 K) reveal that a crucial step in the extraction process of the key antimalarial drug artemisinin by ionic liquids (ILs), namely, precipitation through the addition of water, is driven by artemisinin dehydration due to the differences in the water's interaction with the bulk ILs, rather than with the artemisinin itself.
