Abstract
The rate constant for the reaction of oxygen atoms with CF3Br (halon 1301) was measured at low pressures in a heated discharge‐flow reactor. The halon concentration was followed gas chromatographically. The likely primary reaction products are CF3 and OBr radicals. Variation of experimental parameters and correlated numerical solutions of the total rate equations indicate that secondary reactions are not significant. The reaction dynamics fit an Arrhenius plot with A = 1.5 ± 0.5 × 10−11 cm3/molecule·sec and Ea = 13.5 ± 1.0 kcal/mole. The application of these studies to flame inhibition indicates that, in diffusion flames at least, CF3Br+O(3P) is a candidate as the inhibition initiating reaction.Keywords
