摘要：
In the production of perfluoroalkylsulfonyl fluorides by electrolytic fluorination of alkylsulfonyl fluoride, the electrolyte contains anhydrous hydrogen fluoride, an alkylsulfonyl fluoride, and at least one additional component selected from alkaline earth fluorides, alkali tetrafluoroborates, alkali hexafluorophosphates, hexafluorophosphoric acid, tetrafluoroboric acid, boron trioxide, boron trifluoride, or mixtures thereof.
