摘要
In this work, a combination of vicinal amino–nitro groups and the hydrazine bridge was developed to synthesize two insensitive and heat-resistant energetic compounds 2,2′-hydrazo-bis(2-amino-3,5-dinitropyridine) (2) and 2,2′-hydrazo-bis(4-amino-3,5-dinitropyridine) (4) through a simple method. The structures of compound 2 and 4 were adequately characterized by NMR (1H and 13C), elemental analysis, differential scanning calorimetry, and infrared spectroscopy. Notably, compound 2 possesses thermal stability (Td = 350 °C) higher than that of 2-bis(2,4,6-trinitrophenyl) ethene (HNS) (Td = 318 °C) and comparable to that of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) (Td = 350 °C). Moreover, compound 2 possess a higher energy level (2: D = 8759 m s–1, P: 34.1 GPa) than HNS (7612 m s–1, P: 24.3 GPa) and TATB (8114 m s–1, P: 31.4 GPa). These consequences indicate that compound 2 has potential applications as an insensitive and heat-resistant explosive.
