三硝基均苯三酚金属(Li, Na, K,Mg)化合物的快速热分解
利用温度快速跃升傅立叶变换红外(T-jump/FTIR)原位分析技术对三硝基均苯三酚(TNPG, 2,4,6-三硝基-1,3,5-苯三酚)的锂、钠、钾、镁金属盐的快速热分解反应过程进行了系统研究. 确定了三硝基均苯三酚系列化合物快速热分解过程产生的可挥发金属化合物的类型, 得到了快速热分解过程主要红外活性气体产物的种类、分布及浓度随时间的变化关系曲线, 提出了其快速热分解方程式. 利用计算机模拟方法, 采用REAL程序对三硝基均苯三酚系列化合物的燃烧性能(燃烧产物和燃烧温度等参数)进行了计算, 与T-jump/FTIR分析技术得到的实验结果进行比较分析和讨论.

Flash Pyrolysis of Trinitrophloroglucinol Metallic (Li, Na, K, Mg) Compounds
The T-jump/FTIR(Fourier transforminfrared) spectroscopy technique was used to study the flash pyrolysis of metallic (Li, Na, K, Mg) compounds of trinitrophloroglucinol (TNPG, 2,4,6-trinitro-1,3,5-trihydroxybenzene). Volatile metallic compounds liberated during the flash pyrolysis of trinitrophloroglucinol metallic (Li, Na, K, Mg) compounds were determined. A curve showing the concentration of gas with time during flash pyrolysis was also derived. A qualitative and quantitative analysis of the main IR-active gas products resulted from the thermal decomposition was carried out. The REAL program was used to study the components of the combustion products, reaction thermodynamics and the burning temperature of trinitrophloroglucinol metallic (Li, Na, K, Mg) compounds, which were compared with experimental results gained fromthe T-jump/FTIR spectroscopy technique.
