Mixed acid nitration of electrochemically generated 4,4′,5,5′-tetraamino-3,3′-azo-bis-1,2,4-triazole (TAABT) generated the novel energetic material 4,4′-dinitrimino-5,5′-diamino-3,3′-azo-bis-1,2,4-triazole (DNDAABT). Various energetic salts of DNDAABT were also prepared and characterized to confirm their structures and determine their explosive sensitivities and performances. The free acid of DNDAABT exists as a zwitterionic molecule that leads to a high-density material with predicted detonation parameters comparable to those of TKX-50 (bis(hydroxylammonium) 5,5′-bis(tetrazolate-1 N-oxide). Due to the insensitive nature of TAABT, it was predicted that DNDAABT would demonstrate remarkably low sensitivities for a primary N-nitramine. However, it was found that DNDAABT and all salts produced have primary explosive sensitivities, albeit with relatively high thermal stabilities for primary N-nitramines.

4,4'-Dinitrimino-5,5'-diamino-3,3'-azo-bis-1,2,4-triazole：一种高性能的两性离子高能材料

电化学生成的 4,4',5,5'-tetraamino-3,3'-azo-bis-1,2,4-triazole (TAABT) 的混合酸硝化生成新型含能材料 4,4'-dinitrimino-5 ,5'-diamino-3,3'-azo-bis-1,2,4-triazole (DNDAABT)。还制备并表征了 DNDAABT 的各种含能盐，以确认其结构并确定其爆炸敏感性和性能。DNDAABT 的游离酸作为两性离子分子存在，导致高密度材料具有与 TKX-50（双（羟基铵）5,5'-双（四唑盐-1 N-氧化物）相当的预测爆轰参数）。由于 TAABT 的不敏感性质，预计 DNDAABT 对原发N 的敏感性非常低-硝胺。然而，发现 DNDAABT 和所有生产的盐都具有初级爆炸敏感性，尽管对初级N-硝胺具有相对较高的热稳定性。
