1-Dodecyl-3-methylimidazolium chloride (34.16 g, 0.119 moles) was partially dissolved in reagent-grade acetone (400 ml) in a large round-bottomed flask and stirred vigorously. Potassium 1,1,2,2-tetrafluoroethanesulfonate (TFES-K, 26.24 g, 0.119 moles) was added to reagent grade acetone (400 ml) in a separate round-bottomed flask, and this solution was carefully added to the 1-dodecyl-3-methylimidazolium chloride solution. The reaction mixture was heated at 60 degrees C. under reflux for approximately 16 hours. The reaction mixture was then filtered using a large frit glass funnel to remove the white KCl precipitate formed, and the filtrate was placed on a rotary evaporator for 4 hours to remove the acetone.
