  Processes For Producing High-Purity N,N-Dialkyl Perfluoroalkylsulfonamide

  摘要：

  Processes for producing a N,N-dialkyl perfluoroalkyl-sulfonamide product of the formula R f —S(O) 2 —NR a R b (I) in which R f represents fully or partially fluorinated alkyl groups with carbon 1 to 12 and R a and R b represents linear or branched or cyclic alkyl, alkene or alkyne groups with carbon 1 to 12, wherein R a =R b or R a ≠R b . In some embodiments, a reaction proceeds by contacting a perfluoroalkylsulfonyl halide of the formula: X—S(O) 2 —R f , (II), in which X represents F, Cl, Br or I, with dialkylamine of the formula HNR a R b , under conditions sufficient to produce the desired N,N-dialkyl perfluoroalkylsulfonamide product of Formula I. In some embodiments, the reaction is carried out using a solvent of Formula I.

  Twenty derivatives of N,N-dialkyl perfluoroalkanesulfonamides, n-CmF2m + 1SO2NRR′ (m = 1, 2, 4, 6, 8; R, R′ = CH3, CH2CH3 or CH2CH2OCH3), have been prepared and characterized. Their fundamental physicochemical properties, including melting point, density, viscosity and dielectric constant, are determined. The influences of structural variations in both the perfluoroalkyl and alkyl chains on the above
