The reaction of CH2OH with O2 was studied in an isothermal flow system at 296 K. A rate coefficient, k1 (296 K) = (6.4 ± 1.5) × 1012 cm3 mol−1 s−1, has been determined for the overall reaction CH2OH + O2 → product(s) (1) by monitoring the decay of the LMR signal of the CH2OH radical. A value of (6.3 ± 2.8) × 1012 cm3 mol−s−1 has been obtained for the overall rate coefficient by following the formation of the product HO2 radicals in the specific reaction channel CH2OH + O2 → HO2 + CH2O.(1a) No dependence on pressure of k1 was observed in the pressure range 0.69 ≦ P/mbar ≦ 6.50 studied. A complex mechanism has been proposed for the formation of HO2 and CH2O in the reaction.
