The reaction CH3+OH plays an important role for the modelling of laminar burning velocities of CH4-air flames. Experimental data on its rate coefficient are scarce and the importance of this reaction is shown by rate coefficients obtained recently from theoretical models. For CH3OH-air flames the reaction CH2OH+H#x2192; products is likewise important and to a lesser extent so is the reaction CH3O+H. At higher temperatures no experimental data exist on these reactions and it has been tried in recent modelling studies to calculate rate coefficients for CH3O+H from those of CH3+OH by using equilibrium considerations. This approach if applied to a multiple channel reaction is generally dangerous, and indeed in this particular case by confusing the CH3O and CH2OH exit channels a rather misleading rate expression was obtained for the reaction CH3O+H#x2192;.CH3+OH.
