Adequate primary explosives such as lead azide mostly contain toxic ingredients, which have to be replaced. A new candidate that shows high potential, potassium 1,1'-dinitramino-5,5'-bistetrazolate (K2DNABT), was synthesized by a sophisticated synthetic procedure based on dimethylcarbonate and glyoxal. It was intensively characterized for its chemical (X-ray diffraction, EA, NMR and vibrational spectroscopy) and physico-chemical properties (sensitivity towards impact, friction, and electrostatic, DSC). The obtained primary explosive combines good thermal stability with the desired mechanical stability. Owing to its high heat of formation (326 kJ mol(-1)) and density (2.11 g cm(-3)), impressive values for its detonation velocity (8330 m s(-1)) and pressure (311 kbar) were computed. Its superior calculated performance output was successfully confirmed and demonstrated by different convenient energetic test methods.
足够的初级炸药，如叠氮化铅，大多含有有毒成分，需要加以替换。一种新的候选物，即钾 1,1'-二硝氨基-5,5'-双四唑（K2DNABT），通过基于碳酸二甲酯和乙二醛的复杂合成程序合成。对其化学性质（X 射线衍射、EA、NMR 和振动光谱）和物理化学性质（对冲击、摩擦和静电的敏感性、DSC）进行了深入的表征。所得到的初级炸药将良好的热稳定性与所需的机械稳定性结合在一起。由于其高生成热（326 kJ mol(-1))和密度（2.11 g cm(-3))，其爆轰速度（8330 m s(-1))和压力（311 kbar)的计算值非常可观。通过不同的方便的能量测试方法，成功地证实和证明了其优越的计算性能输出。
