Nitro-tetrazole based high performing explosives: Recent overview of synthesis and energetic properties

Defence Technology, Год журнала: 2021, Номер 17(6), С. 1995 - 2010

Опубликована: Фев. 9, 2021

Heterocyclic skeleton (Azoles) and different energetic groups containing high performing explosives are highly emerged in recent years to meet the challenging requirements of materials both military civilian applications with improved performance. For this purpose tetrazole (Azole) is identified as an attractive heterocyclic backbone functional nitro (-NO2), nitrato (-ONO2), nitrimino (-NNO2), nitramino (–NH–NO2) replace traditionally used explosives. The based compounds having these demonstrated advanced performance (detonation velocity pressure), densities, heat formation (HOF) became a potential replacement traditional such RDX. This review presents summary recently reported nitro-tetrazole poly-nitro, di/mono-nitro, nitrato/nitramino/nitrimino, bridged/bis/di groups, describing their preparation methods, advance properties, further high-performing explosives, especially those last decade. aims provide fresh concept for designing together major challenges perspectives.

Taming nitroformate through encapsulation with nitrogen-rich hydrogen-bonded organic frameworks

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Апрель 9, 2021

Abstract Owing to its simple preparation and high oxygen content, nitroformate [ − C(NO 2 ) 3 , NF] is an extremely attractive oxidant component for propellants explosives. However, the poor thermostability of NF-based derivatives has been unconquerable barrier more than 150 years, thus hindering application. In this study, first example a nitrogen-rich hydrogen-bonded organic framework (HOF-NF) designed constructed through self-assembly in energetic materials, which NF anions are trapped pores resulting via dual force ionic hydrogen bonds from strengthened framework. These factors lead decomposition temperature HOF-NF moiety being 200 °C, exceeds challenge thermal stability over 180 °C time among compounds. A large number compounds with stabilities excellent properties can be synthesized on basis work.
