Notes:
Novel modeling and sensitivity analysis techniques are used with experimental data obtained from discharge flow–resonance fluorescence experiments to evaluate the product branching ratio of OH+H2CO. Two channels are considered: the H-atom abstraction reaction (R2) to form HCO and H2O; and the addition reaction (R17) followed by rearrangement and decomposition to form HCOOH and H. The rate constant values obtained at 298 K are kR2 =(7.75±1.24)×10−12 cm3/molecule s and kR17=(0.2+0.8−0.2) ×10−12 cm3/molecule s. The results demonstrate that the reaction proceeds almost exclusively via the H-atom abstraction pathway.
