Notes:
Fast thermolysis/FTIR spectroscopy of [H3NCH2CH2NH3]-(NO3)2 (EDD), [H2N(CH2CH2)2NH2](NO3)2 (PIPDN), and [HN(CH2CH2)3NH](NO3)2(DABCOD) and new oxonium nitrate (H3O+NO-3) double salts of PIPDN and DABCOD is described. EDD initially yields HNO3 and then small molecule decomposition products from redox reactions when heated at ≥ 100°C (dcc.). PIPDN initially yields HNO3, but then generates a significant amount of N,N′-dinitrosopiperazine along with small molecule fragments. DABCOD produces no HNO3(g), but instead gives CH2O, N,N′-dinitrosopiperazine and small molecule products. These patterns are entirely consistent with the behavior observed for primary, secondary and teritary ammonium mononitrate salts in our previous work. The presence of nitrosamines strongly increases the health hazard of the matcrials upon heating. No nitramines were detected as thermolysis products. Thermolysis of the oxonium nitrate double salts liberates HNO3 and H2O at a relatively low temperature (≥ 60 °C). Above this temperature, the thenmolysis proceeds in the same way as that of pure PIPDN and DABCOD. The crystal structure of PIPDN is described.
