A family of new asymmetric N-methylene-C linked nitropyrazoles and 1,2,4-triazol-3-one based thermally stable energetic materials with reduced sensitivity has been synthesized. Background image via Canva.
The synthetic methods and physicochemical properties of geminal dinitro and trinitromethyl substituted aliphatic compounds, monocyclic azoles, bisazoles, fused heterocycles, and cage adamantanes are reviewed.
This study presents an empirical method to design and synthesis of a series of pyrazole-triazole derivatives, which emerges and provides efficient guidelines for the design of new HEDMs in the future.
Pyrazine-bridged C–C bonded hexanitro compound and energetic salts show high density, strong thermal stability, competitive detonation performance and low sensitivity, offering a balanced strategy for next-generation insensitive energetic materials.
In this study, a series of explosives based on the DPT framework were synthesized. Among all the compounds, DPTO, DPPT, DPBT and PBPT exhibit excellent thermal stabilities with the Td over 300 °C, while their detonation velocity exceeds 8700 m s−1.
