Ensuring the security for long-term storage of weapons is always of the great cMehilaloncerns in the field of energetic materials. 1,3,5-Triamino-2,4,6-trinitrobenzene (TATB) is a remarkable explosive applied in nuclear weapons where extreme safety is required primarily. Owing to the strong inter or intra molecular hydrogen bonding, TATB shows poor solubility in most solvents. As the result, the particle shape and size of TATB products is hard to regulate, which closely related to the weapons stability. Herein, a new recrystallization method is provided to refine TATB using bicarbonate ionic liquids. Bicarbonate ionic liquids exhibited the record solubility (26.7 wt%) for dissolving TATB explosive. The recrystallized TATB were spherical particles with uniform size and showed extremely insensitivity to impact (>100 J) and friction (>360 N). Moreover, the experimental 1H and 13C NMR spectra of TATB in solution are reported for the first time.

由碳酸氢根离子液体重结晶的超级冲击稳定型TATB炸药,具有创纪录的溶解度
确保高能武器长期储存的安全性始终是高能材料领域的重要挑战。1,3,5-三氨基-2,4,6-三硝基苯(TATB)是一种显着的爆炸物,用于主要要求极高安全性的核武器。由于强烈的分子间或分子内氢键,TATB在大多数溶剂中的溶解性较差。结果,TATB产品的颗粒形状和大小难以调节,这与武器的稳定性密切相关。在此,提供了一种新的重结晶方法,以使用碳酸氢根离子液体精制TATB。碳酸氢根离子液体显示出创纪录的溶解度(26.7 wt%),用于溶解TATB炸药。重结晶的TATB是大小均匀的球形颗粒,对冲击(> 100 J)和摩擦(> 360 N)表现出极大的不敏感性。首次报告了溶液中TATB的1 H和13 C NMR光谱。
