PREPARATION DE SELS D'ACIDE PERFLUOROALCANE SULFINIQUE |
摘要 |
The invention relates to a method for preparing sulphinic perfluoroalkane acid salts. The inventive method is characterised in that it comprises at least one step involving the reaction of least one perfluoroalkyl halide having formula RfX, wherein X represents a chlorine, bromine or iodine atom and Rf represents a linear or branched perfluorinated chain comprising between 1 and 12 carbon atoms, with the alkali metal hydrogensulphite in the presence of an alkaline-earth or alkali-metal hydroxide.
