CO2 Laser Induced Decomposition of CF3Cl: KInetics and Mechanisms

Article abstract of DOI:10.1021/j100345a056

The decomposition of CF3Cl by a CW CO2 laser has been studied over a range of temperatures, 1280-1740 K, and Arrhenius plots show two distinct regimes.At lower temperatures, C2F6 is produced with an activation energy of 86.0 kcal/mol.At high temperatures, C2F6 production is characterized by an activation energy of 54.0 kcal/mol, and now CF4 and CF2Cl2 are detected, being produced at equal rates with an activatuion energy of 86.2 kcal/mol.A reaction mechanism in agreement with these results is presented, and we obtain hitherto unreported activation energy values for the radical-molecule reactions of CF3 and CF2Cl with CF3Cl.
