To determine its fate under environmental conditions, TATB powder was irradiated with simulated sunlight and, in water, under UV light at 254 nm. The hydrolysis of particles submerged in neutral and alkaline solutions was also examined. We found that, by changing experimental conditions (e.g., light source, and mass and physical state of TATB), the intermediates and final products were slightly different
爆炸性 1,3,5-三氨基-2,4,6-三硝基苯 (TATB) 由于其对冲击、冲击和热的极端不敏感,同时提供良好的爆速,因此特别令人感兴趣。为了确定其在环境条件下的命运,TATB 粉末用模拟阳光照射,并在水中,在 254 nm 的紫外光下照射。还检查了浸没在中性和碱性溶液中的颗粒的水解。我们发现,通过改变实验条件(例如,光源、TATB 的质量和物理状态),中间体和最终产品略有不同。单苯并呋喃是两种辐照系统中的主要转化产物。两个小的转化产品,aci在太阳光下检测到 TATB 和 3,5-二氨基-2,4,6-三硝基苯酚的-硝基形式,而 1,3,5-三氨基-2-亚硝基-4,6-二硝基苯、1,3,5在紫外光下产生-三氨基-2,4-二硝基苯和单苯并呋喃。鉴定为 3,5-二氨基-2,4,6-三硝基苯酚的产品与在黑暗条件下(pH 13)和在 50 °C 下孵育或在环境条件下老化的水中形成的产品相同。有趣的是,当只有几毫克的
