Reaction of oxygen atoms with nitromethane and with nitroethane

Abstract

The reaction of oxygen atoms with nitromethane and nitroethane has been studied in a discharge flow system at temperatures between 294 and 473 K. The initial attack involves abstraction of a hydrogen atom, for which the rate expressions are shown to be 10^{(10.18 ± 0.27)} exp (–22.4 ± 1.8 kJ mol^–1)/RT dm³ mol^–1 s^–1 and 10^{(10.50 ± 0.96)} exp (–22.7 ± 7.0 kJ mol^–1)/RT dm³ mol^–1 s^–1 respectively.
