    • PURPOSE: To carry out the reaction of tetrafluoroethylene with sulfur trioxide for the production of the titled substance, preventing the explosion hazard, by diluting the reaction system with a diluent gas at a specific dilution ratio.
      CONSTITUTION: The compound of formula (sultone) is produced by the reaction of CF
      2 =CF
      2 with SO
      3 . The reaction is carried out by diluting the reaction system with a diluent gas at a volume ratio Z of the gaseous phase of 3 in the gaseous phase (SO
      3 +sultone+diluent gas) to ≤Y (=0.16+0.067Z). The diluent gas is tetrafluoroethylene used as a reaction material or an inert gas (preferably N
      2 gas). The ratio X of SO
      3 can be maintained to ≤Y by introducing SO
      3 and CF
      2 =CF
      2 into the reaction system containing the objective sultone.
      USE: Synthetic raw material or synthetic intermediate for various functional fluorine compounds.

    • 目的:为了进行四氟乙烯与三氧化硫的反应,用于制备标题物质,防止爆炸危险,用稀释气体以特定稀释比稀释反应体系。 构成:式(sultone)化合物是通过CF 2 = CF 2与SO 3的反应产生的。 该反应是通过用气相体积比Z为稀释气体稀释反应体系<0.6,并将气相(SO 3 + sultone +稀释气体)中SO 3的比例X保持为<= Y( = 0.16 + 0.067Z)。 稀释气体是用作反应材料或惰性气体(优选N2气体)的四氟乙烯。 通过将SO 3和CF 2 = CF 2引入到含有目标磺内酯的反应体系中,SO 3的比例X可维持在<= Y。 用途:各种功能性氟化合物的合成原料或合成中间体。
