Two novel, thermally stable explosives, 2-fluoro-1,3-diamino-4,6-dinitrobenzene (ZXC-7) and 2-fluoro-1,3,5-triamino-4,6-dinitrobenzene (ZXC-8), are reported. These two compounds can be prepared by means of simple synthetic methods and they show outstanding properties (detonation velocity, detonation pressure, sensitivity toward mechanical stimuli, and temperature of decomposition). Their structures
两种新型的热稳定炸药2-氟-1,3-二氨基-4,6-二硝基苯(ZXC-7)和2-氟-1,3,5-三氨基-4,6-二硝基苯(ZXC-8) ,均已报告。可以通过简单的合成方法制备这两种化合物,它们显示出出色的性能(爆炸速度,爆炸压力,对机械刺激的敏感性和分解温度)。它们的结构与1,3,5-三氨基-2,4,6-三硝基苯(TATB)的结构非常相似。通过质谱和多核(1 H,13 C)NMR光谱对它们进行分离和表征。通过低温单晶X射线衍射确定结晶状态的ZXC-7的结构。根据计算出的标准摩尔摩尔形成焓(CBS-4 M)和密度(通过比重瓶比重计确定),通过使用EXPLO5 V6.01热化学计算机代码来预测Chapman-Jouguet的爆轰性能。确定了ZXC-7和ZXC-8对冲击和摩擦的敏感性。
