Procedure

Ten grams of KO3SCF2CF2COOK were dissolved in 30 ml warm water and placed in a 50 cm×2.5 cm glass column containing a 20 cm bed of "Amberlite IR-120" ion-exchange resin in the acid (H+) form, which had been previously prepared by treating the column with 6 N hydrochloric acid and rinsing with distilled water. The column was eluted with distilled water. The first 150 ml of eluate was concentrated under reduced pressure to yield the hydrate of 3-sulfoperfluoropropionic acid, HO3SCF2CF2COOH.8H2O.
