Abstract
以乙二肟和叠氮化钠(NaN3)为原料,采用一锅法制备了中间体二叠氮基乙二肟(DAG),然后DAG与HCl,Et2O反应合成5,5′-联四唑-1,1′-二羟基二水合物(BTO),BTO与氯化铵发生复分解反应合成了目标化合物5,5′-联四唑-1,1′-二氧氨盐(ABTOX),用X-射线单晶衍射仪对其晶体结构进行表征.采用DTA/TG技术研究了ABTOX的热行为,并测试了其感度.结果表明,该晶体属于正交晶系,空间群为Aba2(41).晶体学参数为:a=1.07165(13)nm,b=1.070 33(13)nm,c=1.329 04(16)nm,V=1.524 4(3)nm3,z=4,D=1.779g/cm3.ABTOX的热分解温度为287.8℃,撞击感度(H50)为46cm,摩擦感度为0.更多还原
