Perfluorinated polycyclic hydrocarbons may be produced in high yield by a three-stage process comprising contacting a cyclic hydrocarbon such as an alkyladamantane with a fluoride of silver, manganese, sulfur or the like under varying reaction conditions, generally in the liquid state, to provide a partially fluorinated cyclic hydrocarbon. This fluorination is followed by a second stage vapor phase reaction with a fluoride of cobalt or the like at temperatures generally just above the boiling point of the material to yield highly fluorinated cyclic compounds, followed by a third stage reaction with the same reagent at substantially higher temperatures to provide the desired perfluorinated material. Alternatively, the partially fluorinated material for use in the second stage may be derived from known sources, using any known partially fluorinated cyclic hydrocarbon. In a further embodiment, a fluidized bed reactor may be substituted for the second and third vapor phase stages described above.
全氟多环碳氢化合物可以通过一个三阶段过程高产率生产,包括将环烃如烷基金刚烷与银、锰、硫等的氟化物在不同反应条件下接触,通常处于液态状态,以提供部分氟化的环烃。这种氟化随后通过第二阶段的气相反应,使用钴等的氟化物,在通常略高于材料的沸点的温度下产生高度氟化的环状化合物,然后通过第三阶段的反应,使用相同的试剂在显著更高的温度下提供所需的全氟化材料。或者,用于第二阶段的部分氟化材料可以源自已知来源,使用任何已知的部分氟化环烃。在另一实施方案中,可以用流化床反应器替代上述第二和第三气相阶段。
