Versuchsvorschrift

The process according to claim 12, wherein the perfluorobutanesulphonate alkaline salts are solubilised in methanol and treated with gaseous hydrochloric acid to give the corresponding perfluorobutanesulphonic acid which, after treatment with PCl5 is transformed into the corresponding perfluorobutanesulphonyl chloride, the latter reacts with 2,2,2-trifluoroethanol and triethylamine in dichloromethane to give 2,2,2-trifluoroethanol perfluorobutanesulphonate, which is recycled in the reaction at phase a).
