- Structure preparation method and performances of high energy heat resistant explosive CPTY
-
The invention discloses a structure preparation method and performances of high energy heat resistant explosive CPTY, namely 3,5-dinitro-4-(3,4,5-triamino-4H-1,2,4-triazole-1-yl)-4H-pyrazole-4-inner salt, and belongs to the technical field of energetic materials. The synthesis method comprises the following steps: first reacting diaminoguanidine hydrochloride with cyanogen bromide to obtain 3,4,5-triaminotriazole bromide, reacting the 3,4,5-triaminotriazole bromide and 3,4,5-trinitropyrazole with potassium hydroxide at a high temperature to obtain the target compound 3,5-dinitro-4-(3,4,5-triamino-4H-1,2,4-triazole-1-yl)-4H-pyrazole-4-inner salt (CPTY). The synthesis method is simple and has large-scale production value. The synthesized energetic compound has a decomposition temperature of359 DEG C and a density of 1.82 g / cm, calculated detonation velocity is 8750 m / s, detonation pressure is 31.5 GPa, and the overall performance is superior to that of standard heat-resistant explosives in the prior art.
