Organofluoro Compounds by Electrochemical Fluorination

Electrochemical fluorination manufacture of perfluoro- compounds with functional groups by electrolysis of the corresponding nonfluorinated compounds in liquid hydrogen fluoride 

The process was first industrially operated (by 3M) in 1951. The flow chart below shows a electrofluorination plant  

Examples of industrially utilized electrofluorination products are e.g. the perfluoroalkylsulfonyl fluorides,
