Recrystallization of 1,3,5-Triamino-2,4,6-trinitrobenzene in Ionic Liquids

Recrystallization of 1,3,5-triamino-2,4,6-trinitrobenzene(TATB) in five kinds of ionic liquids,including 3-ethyl-1-methylimidazolium tetrafluoroborate,3-butyl-1-methylimidazolium tetrafluoroborate,3-butyl-1-methylimidazolium hexafluorophosphorus,3-hexyl-1-methylimidazolium bromine and 3-butyl-1-methylimidazolium chloride(Cl) was investigated.TATB can be dissolved in Cl,and the thermal stability of TATB improved after recrystalization in the ionic liquid was also investigated.The exothermic temperature of the recrystalized TATB(375 ℃) which is higher than that of raw TATB(363 ℃) indicats that the stability of recrystalized TATB is improved.
