The Reaction of Atomic Hydrogen and Azomethane

Abstract

At 27°C the only reaction between atomic hydrogen and azomethane is an addition to the nitrogen double bond to produce s-dimethylhydrazine by a mechanism with a maximum activation energy of 3–4 kcal. At 110°C there is in addition to this a rupture of the C–N bond in azomethane and the N–N bond in the hydrazine producing methane and methylamine, respectively. The energy of activation of each rupture appears to be about 8 kcal. At 195°C an additional reaction is evident involving association of methyl radicals with azomethane.
