Abstract

The invention discloses a di(3-nitro-1,2,4-triazole-5-yl)methylene glycol compound. The structure formula of the compound is as shown in the description. The compound is mainly used for energy-containing materials.

Description

technical field [0001] The present invention relates to an endomethylene-1,2,4-triazole compound, in particular to a bis(3-nitro-1,2,4-triazol-5-yl)methylene glycol compound, It belongs to the field of energetic materials. Background technique [0002] The endomethylene-1,2,4-triazole structure is the basic structural unit of energetic compounds because of its high density, high nitrogen content and high enthalpy of formation. In recent years, researchers have designed and synthesized a series of energetic compounds by combining the endomethylene-1,2,4-triazole structural unit with other energetic groups, basically showing the characteristics of high energy density. For example "5,5'-Dinitrimino-3,3'-methylene-1H-1,2,4-bistriazole-a Metal Free Primary Explosive Combining Excellent Thermal Stability and High Performance", Central European Journal of Energetic Materials, 2011, 8(4 ): 261-278 discloses an energetic compound with an endomethylene-1,2,4-triazole structure——5,5′...
