AI Technical Summary

Problems solved by technology

However, the above two compounds have very significant disadvantages: the presence of polynitro groups will cause the thermal stability of the compound to decrease. For example, the thermal decomposition temperature of DNMNT is only 114°C, which is far lower than 210°C of RDX.
Due to structural limitations, BDNMT also does not have better thermal stability in theory.

Description

technical field [0001] The 1,1'-bis(gem-dinitromethyl)-3,3'-dinitro-5,5'-linked-1,2,4-triazole biguanide salt involved in the present invention is an energetic Compounds are mainly used in explosives and energetic materials. Background technique [0002] The nitro group is a good detonating group and plays an important role in energetic molecules. When the triazole compound with a conjugated structure is connected to the nitro group, it usually has both the compact structure of the triazole and the high detonation performance of the nitro group. specialty. For example, "Trinitromethyl-substituted 5-nitro-or 3-azo-1,2,4-triazoles: synthesis, characterization, and energetic properties" (Journal of the American Chemical Society, 2011, 133 (16): 6464-6471) discloses A triazole compound, 3-gem-dinitromethyl-5-nitro-1,2,4-triazole (DNMNT), has a density of 1.91 g cm -3 , detonation velocity 9.229km·s -1 , detonation pressure 38.41GPa, detonation performance is equivalent to HM...
