Reaction Steps
n-C4F9OC4H8SO3K was prepared from normal-perfluorobutyl acid fluoride, KF and 1,4-butane sultone and isolated in 92% purity as described in U.S. Pat. No. 6,890,452, as FC-11. The sulfonic acid salt was converted to the corresponding acid through an ion-exchange column packaged with acidified Amberlite IR-120 ion-exchange resin. The corresponding ammonium salt was prepared by adjusting the pH of C4F9O(CH2)4SO3H aqueous solution to ˜10 with 10% aqueous ammonium solution.
