✦ Synopsis
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 CF 3 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 CF 2 carbene may take place on the surface of supporters to produce CF 3 radical and carbon.
