The thermal decomposition of N-nitro-N-bis-(2,2-dinitropropyl)amine in m-dinitrobenzene medium proceeds with autoacceleration. The first step of the process is monomolecular.
The nature of the substituents in nitroamines does not influence the energy of dissociation of the N-NO2 bond.
The increased reactivity of the compounds studied in comparison with N-nitrodialkylamines is due to the positive contribution to the entropy of activation, associated with steric hindrances to rotation around the N-NO2 bond.
The enthalpy of formation of the CH3C(NO2)2CH2NCH2C(NO2)2CH3 radical was determined.
