By reacting atomic hydrogen with mixtures of CH3Br and CO to generate CH3 and CHO radicals simultaneously, the formation of CH3CHO by combination of CH3 with CHO has been observed.For experiments at 473K, it is shown that the rate coefficient for this reaction is twice the product of the square roots of those for mutual termination of CH3 and CHO, to within the error limits.With this approximation, a model reaction scheme has been developed to analyse the effects of varying the pressures of CH3Br and CO; thereby the yields of CH3CHO produced by the combination of CHO with CH3 have been derived in the temperature range 373-473K, with a total pressure of 600 Torr.The yield appears to decrease slightly with increasing temperature, falling from ca. 0.55 at 373K to ca. 0.42 at 473K.The competing reaction generates CH4 plus CO, and it is argued that the two reactions proceed through different transition states.By computer simulation, it is shown that deviations from the model at lower temperatures are due to participation of CH3CO.
