Notes:
The new flowtube reactor employing dissociative electron attachment to produce radicals and high-pressure photoionization in the mass spectrometric detection of radicals is described. The system has been applied to a study of the association reactions of CHCl2 and CCl3 with O2 in a great excess of helium at total densities below 1017 cm-3 over the temperature range 286 to 332 K. Both reactions display a strong negative temperature coefficient. The results can be parameterized in the form k0(CHCl2 + O2) = (4.3 ± 0.2) × 10-31(T/300)-6.7±0.7 cm6 s-1, k0(CCl3 + O2) = (2.7 ± 0.2) × 10-31(T/300)-8.7±1.0 cm6 s-1. © 1994 John Wiley & Sons, Inc.
