Energetic salts based on the 4-amino-3,5-dinitropyrazolate anion and selected nitrogen-rich cations were prepared in high yield by neutralization or metathesis reactions. Their key properties of the resulting energetic salts, such as melting point, thermal stability (169â303 °C), density (1.54â1.84 g cmâ3), impact sensitivity (>60 J), heat of formation, and detonation pressure (20.99â32.55 GPa) and velocity (7712â8751 m sâ1), were measured or calculated. As highly insensitive energetic materials, salts 9 (32.55 GPa, 8743 m sâ1) and 11 (28.85 GPa, 8751 m sâ1) are comparable with 1,3,5-triamino-2,4,6-trinitrobenzene (TATB, 31.15 GPa and 8114 m sâ1).
通过中和反应或偏合成反应,高产制备了基于 4-氨基-3,5-二硝基吡唑酸阴离子和特定富氮阳离子的高能盐。对所制备的高能盐的关键特性,如熔点、热稳定性(169â303 °C)、密度(1.54â1.84 g cmâ3)、冲击灵敏度(>60 J)、形成热、引爆压力(20.99â32.55 GPa)和速度(7712â8751 m sâ1)进行了测量或计算。作为高度不敏感的高能材料,盐 9(32.55 GPa,8743 m sâ1)和盐 11(28.85 GPa,8751 m sâ1)与 1,3,5-三氨基-2,4,6-三硝基苯(TATB,31.15 GPa 和 8114 m sâ1)相当。
