الإجراء التجريبي

The solvent was removed under vacuum giving (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)-trioctylphosphonium iodide as a waxy solid (30.5 g). Potassium 1,1,2,2-tetrafluoroethanesulfonate (TFES-K, 13.9 g) was dissolved in reagent grade acetone (100 ml) in a separate round-bottomed flask, and to this was added (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl) -trioctylphosphonium iodide (60 g). 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 Kl precipitate formed, and the filtrate was placed on a rotary evaporator for 4 hours to remove the acetone. The liquid was left for 24 hours at room temperature and then filtered a second time (to remove Kl) to yield the product (62 g) as shown by proton NMR.
