The energetic derivatives of 5-nitro-1,2,3-2H-triazole, which include 2-(methyl or amino)-4-(nitramino, azido, or nitro)-5-nitro-1,2,3-2H-triazoles, were prepared in moderate yields, and confirmed with NMR and IR spectroscopy, and elemental analysis. Their key properties, viz., melting and decomposition temperatures, densities, detonation pressures and velocities, and impact sensitivities, were measured or calculated. Among the new derivatives, 2-amino-4,5-dinitro-1,2,3-2H-triazole exhibits properties (Tm, 94 °C; Td, 190 °C; Ï, 1.83 g cmâ3; P, 36.2 Gpa, vD, 8843 m sâ1, IS, 24 J), comparable with RDX (Tm, 205 °C; Td, 230 °C; Ï, 1.80 g cmâ3; P, 35.0 Gpa, vD, 8762 m sâ1, IS, 7.5 J), and may have potential as a high-performance energetic material.
5-硝基-1,2,3-2H-三唑的能量衍生物,包括2-(甲基或氨基)-4-(硝氨基、叠氮或硝基)-5-硝基-1,2,3-2H-三唑,已在中等产率下制备,并通过核磁共振(NMR)和红外光谱(IR)及元素分析进行了确认。它们的关键特性,如熔点和分解温度、密度、爆轰压力和速度,以及冲击敏感性,均已测量或计算。在新衍生物中,2-氨基-4,5-二硝基-1,2,3-2H-三唑的性质(熔点94°C;分解温度190°C;密度1.83 g/cm³;压力36.2 GPa,爆轰速度8843 m/s,冲击敏感性24 J)与RDX(熔点205°C;分解温度230°C;密度1.80 g/cm³;压力35.0 GPa,爆轰速度8762 m/s,冲击敏感性7.5 J)相当,并可能作为一种高性能能量材料具有潜力。
