Definitions
- the present invention relates to a method for producing perfluoroalkanesulfonyl fluoride.
- the present invention relates to an intermediate compound in the synthesis of perfluoroalkanesulfonic acid and salts thereof (S. Benefice — Malouet, H.Blancoueta 1., J. of Fluorine Chemistry, 31 (1) 986), 319.332), and as a raw material in the synthesis of perphnoleoloalkanesulfonylimides and salts thereof (U.S. Pat. No. 5,072,040, 1991). (Feb.
- PFASF perfluoro-anolecancer-norehoninorefureo-leo-lide
- Pentaphthalene ethane phenol is obtained by interacting the required type of olefin with S 0 2 F 2 in a solvent at a temperature of 110 ° C for 60 hours in the presence of cesium fluoride.
- Methods for producing ninolefnoreolide and heptafluoroisopropanesulfonylfluoride are known (US Patent No. 3,542,864, January 1970, January 24). Day) . This method uses complex cesium fluoride and expensive equipment, and generates toxic and difficult-to-reuse waste. No further development was seen since it was born.
- perfluoroalkanesulfonyl fluoride is obtained by the Simons method (in anhydrous hydrogen fluoride in the presence of sodium fluoride, at a temperature of 10 to 17 ° C, on a nickel anode with sulfur).
- Simons method in anhydrous hydrogen fluoride in the presence of sodium fluoride, at a temperature of 10 to 17 ° C, on a nickel anode with sulfur.
- Is a method of electrochemically fluorinating halogenated hydrocarbon-alkanesulfonyl chlorides containing, with a yield of 79-85%, B rice, Trott, U.S. Pat. No. 8, 1954; ⁇ ; Gramstad, R. N. Haszeldine, J. of Chem. Soc. London, 1957, P. 2640-26-45) It is manufactured by
- the productivity of electrolytic cells is not always constant. That is, it increases during the early stages of electrolysis, then stabilizes for a short period of time, and then decreases rapidly due to anode corrosion and the deposition of resinous products on the anode. Therefore, the above yield of 79-85% is not always constant throughout the process.
- the formation of large amounts of by-products also reduces the efficiency of fluorine and power utilization and makes it difficult to separate the desired product, which mixes with hydrogen fluoride (H F). Separation from HF is a difficult task in itself, but the target product cannot be subsequently separated by any method other than rectification.
- the reaction between an alkane sulfonyl fluoride having a hydrocarbon group and a fluorine gas is used.
- a method for obtaining a fluoroalkanesulfonyl fluoride is known (Kanto Denka Kogyo Co., Ltd., Japanese Patent Application Laid-Open No. 2003-206272), but in this method, a part of a hydrocarbon group is The yield of PFASF in which all hydrogen atoms have been replaced by fluorine atoms is low because many hydrofluoroalkanesulfoninolefluorides in which all hydrogen atoms have been replaced by fluorine atoms are by-produced (1 2%). Disclosure of the invention

- Rf-CF CF 2 S0 Rf-CF-CF 2 Rf-CFH-S0. F ⁇ Rf-CF 2 -S0 2 F
- R f represents the same as defined above.
- the temperature is set based on the physicochemical constants of the perfluoroalkane sultone to be hydrolyzed, i.e. the boiling point of the perfluoroalkane sultone, plus 33 ° C, but this is determined. It is not an important parameter.
- Alkanesulfonylfluora The fluorination process, which uses elemental fluorine to replace the last hydrogen atom in the sulfide, has never been performed before and to our knowledge has not been published in the literature. This process can produce up to 87.5% of the desired product in the above temperature range (0-30 ° C) of the elemental fluorination stage without forming significant decomposition fluorination products. Work in yield.
- the mixture formed as a result of the fluorination is also washed with an aqueous solution of Al2O3 to remove the hydrogen fluoride formed, dried over zeolite or siliceous gel and, if necessary, rectified.
- a solvent is not particularly required, but an inert solvent may be used in the present reaction.
