    • PROBLEM TO BE SOLVED: To provide a method for producing trifluoromethanesulfonyl fluoride in a higher yield and higher purity as compared with those of the conventional production methods.
      SOLUTION: Trifluoromethane sulfonic acid is obtained by reacting a metal hydroxide with trifluoromethanesulfonyl fluoride and then treating with an acid. Then, by reacting phosphorus trichloride and chlorine with the trifluoromethane sulfonic acid, trifluoromethanesulfonyl chloride (CF

      2 Cl) is obtained. Then, by reacting a metal fluoride with the trifluoromethanesulfonyl chloride in the presence of 0.6 to 10.0 mass% water based on 100 mass% metal fluoride, the trifluoromethane sulfonyl fluoride is obtained. Thereby, the trifluoromethanesulfonyl fluoride produced by electrolytic fluorination can be purified by passing through 3 processes in high selectivity and the high purity. It is a very excellent method for producing the same in an industrial scale.

    • PROBLEM TO BE SOLVED: To provide a method for producing a perfluoroalkane sulfinate useful as an intermediate of medicines and pesticide precursors. SOLUTION: A perfluoroalkane sulfonyl halide is reacted with hydrazine to prepare a hydrazine salt of the perfluoroalkane sulfinic acid (RfSO 2 H N 2 H 4 ). The resultant hydrazine salt is reacted with a base such as a hydroxide of an alkali metal to prepare the perfluoroalkane sulfinate. The resultant sulfinate is reacted with a fluoride of an alkali metal or the like, to crystallize the sulfinate. The resultant sulfinate is added with a halide of an alkali metal or the like to prepare the perfluoroalkane sulfinate of high purity. The production method is very useful because it can produce the perfluoroalkane sulfinate safer and easier on a commercial scale, as compared with conventional technologies, and the method greatly reduce waste products.
