摘要
采用一锅煮的方法在二甲基甲酰胺(DMF)中利用3,6-双(1-氢-1,2,3,4-四唑-5-氨基)-1,2,4,5-四嗪(BTATz)和醋酸锌,60℃下合成了BTATz的锌盐,并用元素分析、红外光谱分析和1H-NMR对其进行了结构表征。采用DSC和TG/DTG技术对标题化合物进行了热分解行为及热分解反应动力学研究,计算了热自加速分解温度(T SADT)、热爆炸临界温度(T b)、热点火温度(T TIT)和绝热至爆时间(t TIAD),并以此来评价化合物的热安全性。
A one-pot approach was used to synthesize the title compound Zn2 （C4 H2 N14 ）（CH3 COO）2 was in which 3,6-bis（1H-1,2,3,4-tetrazd-5-ylamino）-1,2,4,5-tetrazine （BTATz）and zinc acetate was mixed in dime-thyl formamide （DMF）at 60℃.Its structure was fully characterized by elemental analysis,1 H NMR spectrosco-py and vibrational spectroscopy （IR）.The thermal behavior and thermal decomposition reaction kinetics were also investigated by DSC and TG/DTG methods.The self-accelerating decomposition temperature （TSADT ）, critical temperatures of thermal explosion （Tb ）,thermal ignition temperature （TTIT ）and the critical tempera-ture of thermal explosion （tTIAD ）were calculated as important information to estimate the thermal stability which indicate the title compound was a kind of potential energetic materials.
