摘要
以三聚氰氯和叠氮化钠为原料,在室温条件下搅拌反应,得到流散性好的白色粉末固体2,4,6-三叠氮-1,3,5-三嗪(TAT),结合元素分析、红外光谱、质谱分析,确定了TAT的化学结构。研究了TAT的热稳定性、真空安定性、感度以及起爆能力等性质。结果表明:TAT的热分解温度为190℃,5s延滞期爆发温度为170℃;在60℃下连续40h放气量仅为0.03m L/g,真空安定性好;爆热为4 375 J/g,比容为700.0 m L/g;静电感度明显低于氮化铅(LA)和斯蒂芬酸铅(LTNR)。TAT具有很强起爆能力,5mg TAT能够有效起爆70mg黑索今。
A kind of green primary explosive of2,4,6-triazdio-1,3,5-triazine(TAT)with good flowability was synthesized by reacting2,4,6-trichloro-[1,3,5]triazine with sodiumazide in water.The structure of TAT was characterized by IR spectroscopy,element analysis and micro-photography,and the thermal properties,explosive properties were also characterized.The thermal decomposition temperature of TAT is190℃and5s explosion temperature is170℃,the decomposition gas capacity is0.03mL/g under60℃for40h in vacuum.Explosion heat and specific volume of TAT are4375J/g,700.0mL/g respectively and the electrostatic sensitivity is lower than those of LA and LTNR.The initiation efficiency of TAT is very well,70mg RDX could be easily initiated by5mg TAT without LTNR.
