Description

technical field [0001] The invention relates to an energetic material, in particular to a 5,5'-azobis(1-nitroaminotetrazole) dipotassium salt compound. Background technique [0002] At present, the research on the design, synthesis and application exploration of nitrogen heterocyclic energetic compounds has attracted widespread attention of researchers from all over the world. These compounds contain a large number of N-N, N=N bonds, have high positive enthalpy of formation, high nitrogen, low The carbon and hydrogen content makes it easier to achieve oxygen balance, and the higher nitrogen content makes the decomposition product mainly nitrogen, and the gas production is relatively large, clean and pollution-free. It has great potential in the fields of mixed explosives, solid propellants and gas generating agents in the future Broad application prospects. 1,5-Diaminotetrazole and its relatives are important precursors of tetrazole energetic compounds. The amino groups in ...
