用差热分析及其在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 NH4ClO4 (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.
