The mechanism for the double radicals reaction of CH3O with ClO has been investigated theoretically at QCISD(T)/6-311＋G(d,p)//B3LYP/6-311＋G(3df,3pd) level. The results show that the reaction has three channels, yielding the products of HOCl＋CH2O, CH2O2＋HCl and CH3Cl＋O2(1Δ), respectively. The route to produce HOCl＋CH2O was most favorable no matter whether it was considered from the viewpoint of kinetics or thermodynamics. Thus, the channel producing HOCl＋CH2O is the main one in agreement with experiment.
