Thermal Decomposition of Azidonitramines

Stepanov R. S., Kruglyakova L. A., Astachov A. M.

Central European Journal of Energetic Materials

2007

Vol. 4, nr 1-2

151-156

The kinetic laws and mechanism of the thermal decomposition of azidonitramines in gaseous phase, melt, and in solutions are discovered. Homolysis is established to be the first order reaction, the limiting stage has Arrhenius's parameters Ea = 144.8-166.5 kJ mole–1, lgA = 13.53-14.97, what is not adequate for monofunctional alkylazides and alkylnitramines. The thermolysis of azidogroup initiates the decomposition. Nitraminogroup in β- or α-position to azidogroup increases the decomposition rate by 1-2 orders correspondingly as compared with δ-position.
