高氯酸铵的热分解

The Thermal Decomposition of Ammonium Perchlorate

用差热分析及其与FTIR联用技术研究了两种粒度高氯酸铵 (AP)的热分解过程 ,提出了AP晶体分解的“局部化学”现象 ,通过FTIR实时跟踪检测气体产物 ,并结合文献报道 ,提出了AP两个阶段分解的不同机理。

The thermal decompositions of two kinds of NH 4ClO 4 (AP) with different grain size were investigated by DTA and TC-FTIR coupling. It is proposed that the decomposition of AP crystal obeys the process of “topochemistry ” and it is explained that there are two steps in the decomposition of the coarse grain size. On the basis of the gaseous products identified by real time and rapid scan FTIR and reported results in the literatures, the different mechanisms of the two steps during AP decomposition process are suggested.
