Notes:
The rate constants for the reactions Cl + CH3OD → CH2OD + HCl (1) and CH2OH + O2 → HO2 + H2CO (2) have been determined in a discharge flow system near 1 torr pressure with detection of radical and molecular species using collision-free sampling mass spectrometry. The rate constant k1, determined from the decay of CH3OD in the presence of excess Cl, is (5.1 ± 1.0) × 10-11 cm3 s-1. This is in reasonable agreement with the only previous measurement of k1. The CH2OH radical was produced by reaction (1) and its reaction with O2 was studied by monitoring the decay of the CH2OH radical in the presence of excess O2. The result is k2 = (8.6 ± 2.0) × 10-12 cm3 s-1. Previous estimates of k2 have differed by nearly an order of magnitude, and our value for k2 supports the more recent high values.
