Thermophysical properties of ionic liquids

Ionic liquids have received significant interest from research groups and industry for a range of novel applications. Many of these require a thorough knowledge of the thermophysical properties of the pure fluids and their mixtures. Despite this need, the necessary experimental data for many properties are scarce and often inconsistent between the various sources. However, by using accurate data, predictive physical models can be developed which are highly useful, and some would consider essential, if ionic liquids are to realise their full potential. This is particularly true if one can use them to design new ionic liquids which maximise key desired attributes. This paper will review some of the recent advances in our understanding, prediction and correlation of selected ionic liquid physical properties.
