Description

technical field [0001] Embodiments of the present invention relate to the field of organic chemistry, more specifically, embodiments of the present invention relate to 3,6,7-triamino-1,2,4-triazolocyclic ionic nitroazole compounds and their preparation methods . Background technique [0002] Ionic energetic materials are a class of energetic compounds with high nitrogen content and high heat of formation, which have attracted much attention in the field of explosive synthesis in recent years. Most of its decomposition products are dinitrogen tetroxide with high density and low vapor pressure, so it is more environmentally friendly than traditional simple explosives. Because of its excellent detonation performance, low mechanical sensitivity, high heat of formation, and excellent thermal stability, it can be used as a high-energy component in military, aerospace, and civil blasting fields. Nitrogen-enriched azole compounds are a good carrier of ionic energetic materials, an...
