Abstract

Ionic liquids (ILs) comprised of the 1-ethyl-3-methylimidazolium [EMIm]+, 1-butyl-3-methylimidazolium [BMIm]+, or butyl¬methyl-pyrrolidinium [Pyr14]+ cation and fluorophosphate anions with three, two, or one pentafluorethyl substituent bonded to phosphorus [mer-(C2F5)3PF3]– (FAP3), [trans-(C2F5)2PF4]–...
