A facile synthetic protocol was developed to synthesize unique energetic salts based on 4,6‐dihydrazino‐1,3,5‐triazine‐2‐one in good to high yield from commercial sources. The process was found to be practical and easily scalable. The resulting energetic compounds show good to excellent thermal stability with decomposition temperatures ranging from 180 °C to 331 °C. They possess low sensitivity to impact and friction (IS>20 J, FS>360 N), as well as positive enthalpy of formation (148.9∼1381.7 kJ mol⁻¹). Their detonation velocity (V_D) values locate between 8301 m s⁻¹ and 9282 m s⁻¹, and detonation pressure (P) values range from 26.1 GPa to 37.2 GPa, in some cases, which are comparable to those of HMX. From the view of sensitivity and energy level, some of the energetic compounds prepared in this work exhibit potential as insensitive excellent performance energetic materials.

具有低冲击和摩擦敏感性的对称4,6-二肼基-1,3,5-三嗪-2-一阳离子的新高能离子衍生物

已开发了一种简便的合成方案，可从商业来源以高产率或高产率合成基于4,6-二肼基-1,3,5-三嗪-2-2-1的独特高能盐。发现该过程是实用的并且易于扩展。所得的高能化合物在分解温度为180°C至331°C的范围内显示出良好至极好的热稳定性。它们对冲击和摩擦的敏感性低（IS> 20 J，FS> 360 N），并且具有正的形成焓（148.9〜1381.7 kJ mol ^-1）。它们的爆震速度（V _D）值介于8301 m s ^-1和9282 m s ^-1之间，爆震压力（P）值的范围从26.1 GPa到37.2 GPa，在某些情况下，与HMX相当。从灵敏度和能级的角度来看，在这项工作中制备的一些高能化合物显示出作为不敏感的优异性能的高能材料的潜力。
