the high nitrogen content boron-containing di(1H-1,2,3-triazole-1-yl)dihydroborate anion was successfully synthesized and demonstrated by the single crystal analysis, which could be the alternative for the hydrazines that are prone to serious pollution. Then, based on the di(1H-1,2,3-triazole-1-yl)dihydroborate anion, a series of di(1H-1,2,3-triazole-1-yl)dihydroborate hypergolic ionic liquids were
[显示省略] 成功合成并通过单晶分析证明了一种新型高氮含硼二(1H-1,2,3-三唑-1-基)二氢硼酸盐阴离子,可作为替代品容易造成严重污染的肼类。然后,基于二(1H-1,2,3-三唑-1-基)二氢硼酸盐阴离子,制备了一系列二(1H-1,2,3-三唑-1-基)二氢硼酸盐自溶离子液体,其熔点低于-60°C,密度范围为1.134 g/cm至1.173 g/cm,密度比冲量为374.2至386.5 sg/cm,性能优越。特别是,1,3-二烯丙基-1H-咪唑-3-鎓二(1H-1,2,3-三唑-1-基)二氢硼酸盐具有低点火延迟时间(36 ms)、高燃烧值形成焓(2.08 kJ/g),显示出火箭燃料的良好潜力。
