Notes

Abstract: A recent ab initio study suggested that gaseous metal oxides can directly abstract H atoms from hydrocarbons, but with considerable barriers. To try to confirm the occurrence of such reactions, the title reaction has been studied in a high-temperature fast-flow reactor. The data are well described by the fitting expression k(590-1380 K) = 9.6 x 10⁻³⁹ (T/K)(7.96) exp(2468 K/T) cm³ molecule⁻¹ s⁻¹, with 2σ precision limits varying with temperature from ± 4% to ± 12%. The corresponding 2σ accuracy limits are about ± 25%. Comparison of this result to further ab initio and conventional transition-state theory calculations suggests that direct abstraction indeed can occur at the higher temperatures but that one or more other channels, possible involving AIO insertion into a C-H bond, dominate in the initial attack step. The potential implications of this work for catalytic conversion of methane to higher hydrocarbons are considered.
