Description

technical field [0001] The invention relates to a 4,6-dinitrobenzotriazole-1-oxide amidinourea salt compound, which belongs to the field of energetic materials. technical background [0002] Energetic ionic salts are a new class of energetic materials with unique properties developed in recent years. They have advantages that non-ionic molecules do not have, such as good thermal stability, high density and energy, and low vulnerability. In recent years, benzotriazole-1-oxide energetic compounds have become a research hotspot of energetic materials due to their insensitivity. For example, T.H.Klapotke, Carolin Pluger, Muhamed Suceska. Zwitterionic explosives based on 4,6-dinitrobenzotriazol-3-ium-1-oxide. New trends in research of energetic materials, Czech Republic, 2014, 754-768 discloses 4,6- The structure of dinitrobenzo even triazole-1-oxide and its partial physicochemical detonation properties, its structure is as shown in (II): [0003] [0004] The nitrogen conte...
