【摘要】 CL-20(2,4,6,8,10,12-六硝基-2,4,6,8,10,12-六氮杂四环[5.5.0.0.0]十二烷,C₆H₆N₁₂O₁₂,结构式如图1)是目前已知能够实际应用的能力最高、威力最强的非核单质炸药,爆轰速度高达9500米/秒,称为第四代炸药。1987年美国首先合成出了CL-20,我国近年来在该炸药的合成、爆炸性能等方面也做了很多研究。研究表明,单质炸药的爆炸性能除了与有机杂质有关之外,爆炸物中存在的无机离子纯度对于提高其爆炸性能也是至关重要的。单质炸药工业品经过溶剂热过滤、水煮洗和溶剂多次重结晶精制后残存的无机杂质一般为惰性无机杂质,多为无机盐等,这些杂质的存在往往会影响单质炸药的稳定性,阻碍其在弹药中的应用[1]。测流出物电导变化的一种色谱方法。可以进行多种离子分离和检测,具有灵敏、快速、选择性佳等特点。本研究采用离子色谱法,通过选择合适的色谱柱和流动相,对CL-20成品中无机阴、阳离子残留进行准确的定性和定量分析[2]。更多还原

【Abstract】 CL-20(2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.0.0]dodecane,C₆H₆N₁₂O₁₂, Fig.1), as the new generation and the highest energy density explosivecompound, has been extremely concerned both around its synthesis and explosive property. Besides the organic impurities, inorganic ion purities existing in the explosives were alsocrucial to improve their explosive performance since the purity of energetic material issignificantly contributed to it. Moreover, the high content of inorganic anion could also resultin the corrosion of the cartridge[1]. Ion chromatography is a method that can perform a variety of ion separation and detection methods. It is an advanced instrument analysis method that combines sensitivity, rapidity, selectivity, and simultaneous determination of multiple ions[2]. In this study, we systematically detected the impurities ofcationic and anionic in CL-20 samples by ion chromatography（Fig.2）.更多还原
