摘要 用TGFTIR技术研究了2,4,6三硝基甲苯(TNT)在高纯氮气和等速升温(10℃/min)条件下的缓慢热分解行为,测定了分解气体产物的组成。实验表明TNT在224.16℃时分解速度达到最大,其主要分解产物为1,3,5三硝基苯和CO2。由此推断的TNT缓慢热分解过程、步骤以及TNT的热分解机理与Shackelford报道的一致。 The thermal decomposition behavior of TNT was investigated in pure N 2 with constant rate controlled heating. By means of TG FTIR,the evoloved gases,mainly 1,3,5 trinitrobenzene and CO 2,were determined. The results show that the thermal decomposition process of TNT and its mechanism conform to the conclusion reported by Shackelford.
