実験手順
The obtained solution was heated to its boiling point until evaporation of 402 g of water, and the remaining liquid was cooled to 30° C. to cause precipitation of crystals 0.5 to 1 mm in size. The precipitate was separated by suction filtration and was dried to obtain 230 g of a crystalline powder, which consisted of 223.1 g (97.0 wt%) of C2F5SO3K, 5.5 g (2.4 wt%) of KOH and 1.4 g (0.6 wt%) of KF. Acid decomposition of this sulfonate powder and distillation of the reaction product were performed in the same manner as in Example 3. As the result C2F5SO3H of more than 99% purity was obtained.
