A new insensitive energetic material 2’-methyl-3-nitro-2’H-[1,3’-bi(1,2,4-triazole)]-5,5’-diamine (1) was prepared by a three-step synthesis from commercially available chemicals. The energetic title compound was comprehensively characterized by various means, including FT-IR, multinuclear (1H, 13C, 14N) NMR spectroscopy, elemental analysis, HPLC and thermal analysis. The sensitivities of the synthesized...
The direct nitrolysis of DPT to synthesize HMX with ionic liquids (ILs) as catalysts was investigated. The results showed that [Et3NH] HSO4 was the best catalyst among 18 ILs used and the yield of HMX was up to 61% against 45% without IL. The ILs could be effciently recovered by simple distillation and extraction after reaction without any apparent loss of catalytic activity even after 10 times recycling.
