A novel synthesis method for nitrogen-rich energetic frameworks containing bistetrazoles: assembling an advanced high-energy density material with high nitrogen content and good oxygen balance
The synthesis of bistetrazole via a one-step process including substitution-cyclisation-cracking reaction has been reported for the first time. The combination of a nitrogen-rich energetic framework and a high oxygen detonation group perfectly fulfills the target of maintaining a high level of nitro...

Zusammenfassung: | The synthesis of bistetrazole
via
a one-step process including substitution-cyclisation-cracking reaction has been reported for the first time. The combination of a nitrogen-rich energetic framework and a high oxygen detonation group perfectly fulfills the target of maintaining a high level of nitrogen content and good oxygen balance while avoiding the safety risks.

) and superior detonation velocity (

) to RDX (

). After the introduction of dinitromethyl high oxygen groups, the target compound
BDNTT
has an oxygen balance of −11.6% and a high crystal density up to 1.914 g cm

,
P
= 39.3 GPa). At the same time, the nitrogen content and oxygen balance of the
BDNTT
reached a decent level of 54.1% and −11.6%, respectively. Future researchers can use this study as experience to design advanced high-energy density materials.
Target compound
BDNTT
exhibits excellent detonation performance and indicates the potential as a novel type of high-energy density material (HEDM). |
