摘　　要：用T-Jump/FTIR联用技术研究了模拟燃烧条件下AP的快速热裂解。在不同压力的高纯氮气条件下,以1000K.s-1的升温速率达到设定的温度(874和1274K)快速分解,用快速扫描傅里叶变换红外光谱原位实时分析分解产物的种类和浓度变化。结果表明,AP热裂解主要气相产物为NO2,N2O,NO,HCl和NOCl等,实验温度和压力都使AP快速热裂解气相产物N2O/NO2,NO/NO2和NO/NOCl的比值提高,因此认为AP不但存在凝聚相和非均相的气相/凝聚相反应,而且还有主要气相产物之间的"后续反应"。The fast thermolysis processes of ammonium perchlorate （AP） and its chemical reaction mechanism under certain simulated conditions of combustion were systematically studied by means of T-Jump/FTIR technique.AP was flash-pyrolyzed under different pressure nitrogen atmosphere,with the heating rate of 1 000 K·s-1 and the set temperatures of 874 and 1 274 K.Thereafter,the real time species and concentration of its gaseous products were obtained and identified by using rapid scanning Fourier transform infrared （FTIR） in-situ spectroscopy.It was indicated that the main gaseous products of AP thermolysis is composed of NO2,N2O,NO,HCl and NClO.Interestingly,the values of N2O/NO2,NO/NO2 and NO/NClO are increased while the test temperature or pressure is elevated.It is suggested that the transformation of condensed phase and heterogeneous gas/condensed phase was probably arises and the ＂following reactions＂ among the main gaseous products may also take place in the fast thermolysis process of AP.
