摘要：

The concentration of CF2 produced via trifluoromethane, CF3H, dissociation behind reflected shock waves is measured by molecular resonance absorption spectroscopy method within wide ranges of CF3H concentrations, temperatures, and pressures (38 ae<currency> n[CF3H] ae<currency> 27000 ppm, 1180 ae<currency> T ae<currency> 2780 K, and P = 1.5-18 bar). The heat release of CF2 radical formation in trifluoromethane pyrolysis is experimentally determined. We analyze the experimental data obtained at low and high pressures and find the normalization factor for the best coincidence of those data. We determine the activation energy E (a) at low and high pressures and obtain the generalized activation energy E (a) for all the experimental data.
