4‐Amino‐1,2,4‐triazolium nitrate (4‐ATN) is an energetic and non‐sensitive ionic liquid, which was introduced as a good candidate in previous works for the replacement of 2,4,6‐trinitrotoluene (TNT) in melt‐cast explosives. Since previous studies used pure nitric acid for nitration of 4‐ATN, the effect of the use of low price industrial nitric acids (50 %, 70 % and 98 %) is investigated on the percent
硝酸4-氨基1,2,4-三唑鎓(4-ATN)是一种高能且不敏感的离子液体,在以前的工作中被引入作为替代2,4,6-三硝基甲苯(TNT)的良好候选物)在熔铸炸药中。由于先前的研究使用纯硝酸对4-ATN进行硝化,因此研究了使用低价工业硝酸(50%,70%和98%)对4-ATN收率的影响。热重和差示扫描量热法(TGA / DSC)在合成的4-ATN中用不纯的硝酸以10 K · min –1的加热速率进行通过真空系统。所获得的TGA / DSC曲线证实了4-ATN的分解涉及熔化和解离。通过几种无模型技术,应用了4-ATN在各种加热速率下的导数热重曲线(DTG),以获取热解的活化能。所计算的活化能的范围是78.7-87.7千焦·摩尔-1,这是约10千焦·摩尔-1以上的工业TNT的报道活化能(纯度98.2%),即,66-70千焦·摩尔-1。还将4-ATN的爆震性能评估与TNT进行了比较,后者显示出4-
