The Pulsed Homogeneous Laser Pyrolysis (PHLP) of CHClF2 initiated by IOP(20) radiation of TEA-CO2 laser was carried out in the presence of SF6 sensitizer with the mixture components ratio 1:1 under partial pressure of the reactant equal to 1 Torr and 2 Torr.To describe PHLP process in the afterpulse period we suggested a kinetic model of CHClF2 thermal destruction accounting for the inhomogeneity of laser heating of the reaction mixture and its further cooling by the heat conduction mechanism. Applying the standard mathematical procedure for matching the experimental results of the degree of reactant destruction, and the numeric computations of this value made according to the suggested model, the Arrhenius parameters of the reaction of CHClF2 monomolecular conversion in the temperature range of 1000–1200 K were unambiguously determined. The values were obtained for the activation energy Eα = 52.8 ± 0.3 kcal/mol, and the pre-exponential factor A = (2.5 ± 1) · 1012 s−1.
