- Abstract
The rate constant of the reaction between Cl atoms and CHFBr has been measured by chlorine atom resonance fluorescence in a flow reactor at temperatures of 295-368 K and a pressure of ~1.5 Torr. Lining the inner surface of the reactor with F-32L fluoroplastic makes the rate of the heterogeneous loss of chlorine atoms very low ( k ≤ 5 s). The rate constant of the reaction is given by the formula k = (4.23 ± 0.13) × 10 e cm molecule s (with the activation energy in kJ/mol units). The possible role of this reaction in the extinguishing of fires producing high concentrations of chlorine atoms is discussed.
