Procedure

1-Hexadecyl-3-methylimidazolium chloride (17.0 g, 0.0496 moles) was partially dissolved in reagent-grade acetone (100 ml) in a large round-bottomed flask and stirred vigorously. Potassium 1,1,2,2-tetrafluoroethanesulfonate (TFES-K, 10.9 g, 0.0495 moles) was added to reagent grade acetone (100 ml) in a separate round-bottomed flask, and this solution was carefully added to the 1-hexadecyl-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.
