Kinetics of the thermal decomposition of bis-(2,2-dinitropropyl)-N-nitroamine

  • 28 Accesses

Conclusions

  1. 1.

    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.

  2. 2.

    The nature of the substituents in nitroamines does not influence the energy of dissociation of the N-NO2 bond.

  3. 3.

    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.

  4. 4.

    The enthalpy of formation of the CH3C(NO2)2CH2NCH2C(NO2)2CH3 radical was determined.
