The Reactions of Oxygen Atoms with Nitrites.
Abstract
The reaction of free oxygen atoms with methyl nitrite and with ethyl nitrite have been studied in the gas phase at total pressures between 2 and 12 Torr using a discharge-flow system. The initial steps were shown to be O + CH3ONO = OH + H2CO + NO (1) and O + CH3CH2ONO = OH + CH3CHO + NO (12) and their rate co-efficients were found. The large overall oxygen atom consumption in these systems is due to the known subsequent reactions of the acetaldehyde and formaldehyde formed with oxygen atoms and to the reaction O + OH = O2 + H. The Arrhenius parameters found for the first two reactions (1) and (12) are those expected for rupture of primary or secondary C-H bond of normal strength. They are unaffected by the fact that the radical produced can undergo strongly exothermic rupture to an aldehyde plus nitric oxide.
