Sumario: | 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 (1)H and (13)C NMR spectra of TATB in solution are reported for the first time. |
