摘要

During the process of pyrolysis of chlorodifluormethane, trifluoromethane and hexafluoropropylene oxide in the presence of supporters, like activated carbon (AC) and porous aluminum fluoride (PAF), no tetrafluoroethene (TFE) was detected at early time-on-stream (TOS), and some compounds containing CF₃ group were generated instead of the formation of TFE. The pyrolysis process is much different from that without supporters. It is proposed that the disproportionation reaction of CF₂ carbene may take place on the surface of supporters to produce CF₃ radical and carbon.
