Mixtures of hexafluorobenzene and benzene were irradiated in liquid phase by means of a Co gamma source at 20° and at 218° C. Perfluoroheptane and various binary mixtures involving perfluoroheptane, hexafluorobenzene, benzene, and cyclohexane were also irradiated at 20° C. Hexafluorobenzene resembled benzene very closely in its behavior upon radiolysis. Generally the fluorocarbon-hydrocarbon mixtures evolved much more SiF (indicating the formation of HF, which reacts with the glass vessel) than the pure fluorocarbon components. The polymer from hexafluorobenzene-benzene mixtures was probably rich in cyclohexadiene and cyclohexene units, resembling that from pure benzene, and its composition ratio exhibited a strong "alternating" tendency. The results are discussed in terms of free-radical and excited-state mechanisms. At 218° C hexafluorobenzene and also its mixtures with benzene showed qualitative differences from their behavior at 20° C, although the values for SiF and polymer remained moderate.
六氟苯和苯的混合物在液相中于20℃和218℃下用钴γ源进行辐照。全氟庚烷以及包含全氟庚烷、六氟苯、苯和环己烷的各种二元混合物也在20℃下进行辐照。六氟苯在辐射分解时的行为与苯非常相似。一般来说，碳氟化合物 - 碳氢化合物混合物比纯碳氟化合物组分释放出更多的SiF（表明形成了HF，它与玻璃容器发生反应）。六氟苯 - 苯混合物形成的聚合物可能富含环己二烯和环己烯单元，类似于纯苯形成的聚合物，并且其组成比表现出强烈的“交替”趋势。从自由基和激发态机制的角度对结果进行了讨论。在218℃时，六氟苯及其与苯的混合物与它们在20℃时的行为表现出定性差异，尽管SiF和聚合物的值仍然适中。
