Addition of N-ethylamine to a perfluoroalkylsulfonic acid chloride RFSO2Cl has been studied, to obtain the corresponding perfluoroalkylsulfonamide RFSO2NHC2H5. First a two-step synthesis has been considered : transformation of the perfluoroalkylsulfonic acid chloride RFSO2Cl to the corresponding fluoride RFSO2F, and addition of N-ethylamine; the study of the first step is reported. Then, a sulfonamide one-step synthesis involving a fluoride catalysis, is described.
Direct fluorination process for making perfluorinated organic substances

, (2008/06/13)
A liquid phase process for making perfluorinated organic substances which comprises directly contacting in a temperature-controlled reactor a diluted solution or dispersion of a perfluorinateable, organic substance in a liquid, inert medium with a stoichiometric excess of fluorine gas, optionally diluted with an inert gas, to perfluorinate said organic substance at a temperature and a flow rate of inert gas (if used) sufficient to volatilize the resulting by-product hydrogen fluoride, removing said hydrogen fluoride from the reactor as it is produced, and separately removing from the reactor the resultant solution or dispersion of perfluorinated organic substance.
