Thermal Decomposition of Energetic Materials. 40. Fast thermolysis patterns of Alkanediammonium dinitrate salts

Rapid‐scan FTIR/temperature profiling studies of the fast thermal decomposition of alkanediammonium dinitrate salts [H3N(CH2)nNH3](NO3)2, n = 1–4 and 6, are described. All of the salts liberate HNO3 and NH3 early in the first stage. When n = 1–3, small molecule products from redox reactions occur in the second stage of decomposition. When n = 4, 6, the second stage involves cycloclimination to form pyrrolidine (n = 4) and α‐ethlypyrrolidine (n = 6). The temperature of the onset of thermal decomposition is lower when n = 1 than when n is larger. Intra‐ and intermolecular hydrogen bonding are proposed to play a significant role in these decomposition patterns.
