“…2 for 650 • C, for which C 3 F 6 also passes through a maximum; these will be among our primary modeling targets. (A similar sequence occurs during thermolysis of poly(tetrafluoroethylene) [17].) The C 4 F 8 olefin was assigned [16] as predominantly the i-isomer, with only traces of the 2-isomer and none of the 1-isomer, based on IR spectra.…”

“…Possible formation of C 3 F 6 from C 2 F 4 through c-C 4 F 8 : Thermolysis of c-C 4 F 8 in the medium-temperature regime also produces C 3 F 6 , and some have suggested that c-C 4 F 8 , rather than the C 2 F 4 with which it is in rapid equilibrium, is the direct mechanistic source of C 3 F 6 by expelling CF 2 : in step (17). With this assumption, c-C 4 F 8 → C 3 F 6 + CF 2 :…”

“…Entretanto, quando aquecido entre 600 e 700 ºC, o poli(tetrafluoreteno) se degrada produzindo apenas o monômero tetrafluoreteno. 39 O pirograma do teflon obtido a 600 ºC é apresentado na Figura 4. Já acima de 700 ºC ocorre fragmentação, resultando na formação de apenas um produto, sendo este identificado por espectrometria de massas como 1,1,2,3,3,3-hexafluoropropeno.…”
