The reaction kinetics of dimethoxymethane (DMM) towards H atom abstraction by hydroperoxy and methyl peroxy radicals were investigated using the G4 composite method. All the studied reactions were found to be endothermic and non-spontaneous in nature. Canonical Variational Transition State Theory in combination with Small Curvature Tunneling corrections were adopted to calculate the rate coefficients in the temperature range of 400 – 1500K. The Arrhenius expressions for the reaction of DMM with CH3OO• and HO•2 radicals were obtained as ktotal = 1.50 × 10-12 exp (-8159/T) and ktotal = 4.40 × 10-12 exp (-7251/T) cm3molecule-1s-1 respectively.
