Abstract
The polarities of a wide range of ionic liquids have been determined using the Kamlet-Taft empirical polarity scales [small alpha], [small beta] and [small pi]*, with the dye set Reichardt’s Dye, N,N-diethyl-4-nitroaniline and 4-nitroaniline. These have been compared to measurements of these parameters with different dye sets and to different polarity scales. The results emphasise the importance of recognising the role that the nature of the solute plays in determining these scales. It is particularly noted that polarity scales based upon charged solutes can give very different values for the polarity of ionic liquids compared to those based upon neutral probes. Finally, the effects of commonplace impurities in ionic liquids are reported.
