high-nitrogen (N%, 26.7%) and oxygen (O%, 60.9%) content, is deprotonated by alkali and alkaline earth metal bases to form the corresponding metal salts of TNE which are characterized by FT-IR spectroscopy, elemental analysis, and single crystal X-ray diffraction. All the prepared energetic metal salts show excellent thermal stabilities, and the decomposition temperatures of EP-3, EP-4, and EP-5 are higher
四硝基乙烷 (TNE) 是一种具有高氮 (N%, 26.7%) 和氧 (O%, 60.9%) 含量的高能化合物,被碱金属和碱土金属碱去质子化,形成相应的 TNE 金属盐,其特征在于通过 FT-IR 光谱、元素分析和单晶 X 射线衍射。所有制备的含能金属盐都表现出优异的热稳定性,EP-3、EP-4和EP-5的分解温度由于配合物的众多配位键,温度高于 250 °C。此外,利用燃烧热计算富氮盐的形成能量。利用EXPLO5软件计算了爆轰性能,并确定了冲击和摩擦敏感性。EP-7显示出出色的能量性能(P = 30.0 GPa,V D = 8436 ms -1)。EP-3、EP-4、EP-5和EP-8对机械刺激更敏感。TNE 的这些碱金属和碱土金属盐通过原子发射光谱(可见光)显示出良好的单色性,可用作烟火中潜在的火焰着色剂。
