Ionic Liquids

Thermophysical Properties

Solvation and molecular interactions

Solvation is how the understanding of the mechanism of how a solvent dissolves a solute. Ionic liquids have very special solvation capabilities and understanding them may help to design new task specific ionic liquids. We have been particularly interested in the interactions between ionic liquids and water, salt ions, aminoacids, sulphur containing compounds and gases. We use a triple approach to study this problem measuring macroscopic thermodynamic properties, using spectroscopy to directly probe the molecular interactions and molecular simulations (Molecular Dynamics and Monte Carlo) to gather a comprehensive picture of the molecular interactions involved in the solvation on ionic liquids.
Our results concerning the solvation of gases such as CO2, NH3, SO2 and H2S in ionic liquids are quite surprising and general correlations for the solubility of these gases in ionic liquids could be developed. The interactions with salts were also successfully studied and an understanding of the Hofmeister series was achieved.
