Abstract:

The focus of this letter is on melting points (Tm) of 'green' ionic liquids, which have values of Tm around room temperature. To aid in their chemical interpretation, we place some emphasis on Tm as a function of pressure p, in cases where such experimental information is available. Finally, some comments are made on the effects of pressure via isothermal compressibility κT and the velocity vs of sound. Some measurements of κT and vs as a function of p are invoked.

Keywords: 'green' ionic liquids; pressure-dependence of melting; topological defects and melting; wetting index
