Abstract

The invention discloses a 3-gem methyl dinitro-1,2,4-triazole compound. The structural formula of the 3-gem methyl dinitro-1,2,4-triazole compound is shown as (I), and please see the formula in the specification. The 3-gem methyl dinitro-1,2,4-triazole compound is mainly used in the explosive field.

Description

technical field [0001] The invention relates to an energetic material, in particular to a 3-gem-dinitromethyl-1,2,4-triazole compound. Background technique [0002] In recent years, nitrogen-rich azole energetic compounds contain a large number of N-N and N=N bonds in their molecular structure, and the main product of combustion or explosion is non-polluting nitrogen, which makes these compounds have the characteristics of high formation enthalpy and environmental friendliness. At present, researchers at home and abroad have designed and synthesized a variety of azole energetic compounds, such as: 3,5-dinitropyrazole, 5-amino-3-nitro-1,2,4 -triazole, 4-amino-3,5-dinitropyrazole, etc. As a functional group with high energy density, gem-dinitromethyl can be introduced into the molecular structure of the compound, which can not only increase the density of the compound, but also further improve the detonation performance of the compound. Simultaneous introduction of nitrogen-...
