Variation of the anion in ionic liquids leads to a variation in their physical properties. We have previously investigated ionic liquids based on phosphate anions (Liquid Ionic Phosphates - LIPs)and bis(trifyl)imide anions (Polyammonium Ionic Liquid Sulfonylimides - PILS). LIPs were found to be hydrophobic and PILS were found to be hydrophilic. We report here on our continued investigation of anion variation on the properties of ionic liquids, in particular conductivity, melting point and viscosity.
