Perfluorodialkylsulfones were found to react readily with metal hydroxides in water or alcohol solution and with ammonia to form fluorinated sulfonic acid derivatives.
POTASSIUM PERFLUOROALKANESULFONATES AND PROCESS FOR PRODUCTION THEREOF

Page/Page column 17-18, (2008/06/13)
A process for the production of potassium perfluoroalkane- sulfonates which comprises the electrolytic fluorination step of electrofluorinating an alkanesulfonyl halide in anhydrous hydrofluoric acid to obtain a gas containing a perfluoro- alkanesulfonyl fluoride as the main component. The process may further comprise the gas absorption step of reacting the gas with an aqueous solution of potassium hydroxide to form a solution containing a potassium perfluoroalkanesulfonate, the purification step of removing contaminant potassium fluoride, potassium hydroxide and potassium sulfate from the solution, and the concentration/recovery step of subjecting the purified aqueous solution to concentration and drying. In the electrolytic fluorination, the formation of by-products can be inhibited by keeping the proton concentration of the electrolytic solution within the range of 150 to 1500ppm.
