Abstract

The invention discloses a 1,5-di(nitramino)tetrazole diaminotetrazole salt compound with a structural formula shown in (I). The compound is mainly applied to the energetic material field.

Description

technical field [0001] The invention relates to an energetic material, in particular to a 1,5-dinitroaminotetrazole diaminotetrazolium salt compound. Background technique [0002] At present, the design, synthesis and performance research of nitrogen-heteroaromatic ring energetic compounds are widely concerned by energetic material workers. These compounds contain a large number of C-N, C=N, N-N, N=N bonds in their molecules, and have high The positive heat of formation is the main source of energy. The high nitrogen and low carbon hydrogen content makes it easier for this type of compound to achieve oxygen balance, while the high nitrogen content makes the decomposition product mainly nitrogen, which is clean and pollution-free, and has a large gas output. Larger, it has broad application prospects in the fields of mixed explosives, solid propellants and gas generating agents in the future. 1,5-Diaminotetrazole is an important precursor of nitrogen-heterocyclic energetic c...
