Abstract

The invention discloses a 3-fluorodinitromethyl-1, 2, 4-triazole compound. The 3-fluorodinitromethyl-1, 2, 4-triazole compound is shown in the structural formula I shown in the description and is mainly used in the field of explosives.

Description

technical field [0001] The invention relates to an energetic material, in particular to a 3-fluorogemidine-1,2,4-triazole compound. Background technique [0002] In recent years, aza five-membered aromatic ring (such as pyrazole, imidazole, 1,2,4-triazole, etc.) compounds have attracted much attention at home and abroad for their advantages such as high nitrogen content, large gas production, and clean detonation products. Due to the high electronegativity of the nitrogen and oxygen atoms contained in such high-nitrogen compounds, the entire heterocyclic ring system forms a large л-bond conjugated structure similar to benzene rings, so it has the characteristics of good thermal stability and insensitivity. Researchers at home and abroad have designed and synthesized a variety of nitrogen-heterocyclic energetic compounds, such as: 4,5-trinitroimidazole, 4-amino-3,5-dinitropyrazole, 5- Amino-3-nitro-1,2,4-triazole, etc.; as a functional group with high energy density, fluorog...
