以1,1'-二羟基-3,3'-二硝基-5,5'-联-1,2,4-***(DNOBT)为原料,分别与3-氨基-1,2,4-***、草酰肼、二肼基四嗪反应合成了DNOBT的3-氨基-1,2,4-***盐(DNOBT-3-AT)、草酰肼盐(DNOBT-ODH)、二肼基四嗪盐(DNOBT-DHT)三种含能离子盐,用红外光谱、核磁及元素分析对其结构进行了表征;培养了DNOBT-3-AT的单晶,X射线衍射分析表明其晶体为单斜晶系,空间群为P2(1)/c;利用Gaussian 09程序和Kamlet-Jacobs方程计算了DNOBT-3-AT、DNOBT-ODH、DNOBT-DHT的物化与爆轰性能,采用差示扫描量热(DSC)研究了这三种化合物的热性能,结果表明,DNOBT-3-AT、DNOBT-ODH、DNOBT-DHT爆速分别为7736.4,7729.56,7974.64 m·s~(-...

Using 3, 3'-dinitro-5, 5'-bis-1, 2, 4-triazole-1, 1'-diolate(DNOBT) as starting material, three energetic ionic salts (DNOBT-3-AT, DNOBT-ODH, DNOBT-DHT)were synthesized by reaction with 3-amino-1, 2, 4-triazole, oxalyl dihydrazide, 3, 6-dihydrazine-1, 2, 4, 5-tetrazine, respectively, and their structures were characterized by FT-IR, NMR and elementary analysis. The single crystal of DNOBT-3-AT was cultivated, and its crystal structure was determined by X-ray crystallography. It is found that DNOBT-3-AT crystallizes in monoclinic system, space group P2(1)/c. Their physico-chemistry and detonati...
