| Abstract
| - Syntheses are reported for ionic liquids containing 1-methyl-3-octylimidazolium or 1-butyl-4-methylpyridiniumcations and trifluoromethyl sulfonate, dicyanamide, bis(trifluoromethylsulfonyl)imide, or nonafluorobutyl sulfonateanions. Densities, melting points, glass-transition temperatures, solubilities in water, and polarities have beenmeasured. Ionic liquids containing pyridinium cations exhibit higher melting points, lower solubility in water,and higher polarity than those containing imidazolium cations.
