Abstract

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) x 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) x 1012 cm3 mol-1 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 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.
