| Abstract: | In our previous studies of the reactions of the methyl radical with molecular oxygen, we noticed that after the methyl radical has been consumed the reactions which control the concentration of hydroxyl are hydroxyl-hydroxyl recombination, the titled reaction, and the reaction between hydroxyl and formaldehyde. From the long-time temporal behavior of hydroxyl we have been able to extract the rate coefficient for the titled reaction over the temperature range 1580 to 2250 K. When we combine our data with the low temperature data of Klemm et al [J. Chem. Phys. 1980, 72, 1256--1264] we obtain the rate expression k(T) = 2.59 × 10⁻¹⁶ T{sup 1.67} exp(-891/T(K)) cm³s⁻¹. This result is consistent with the earlier recommendation of Herron [J. Phys. Chem. Ref. Data 1988, 17, 967--1026] which is based on a Bond-Energy-Band-Order calculation adjusted to agree with the experimental results at 700 K. |
