摘要
用实时测定凝聚相分解产物的固体原位反应池/快速扫描傅立叶变换红外光谱热技术研究了高氮量硝化棉(14.14%N)的脱硝反应动力学。该反应的动力学参数(活化能和指前因子)用改良的Coats-Redfern法计算。根据所得结果,提出了在403～465K温度范围内描述高氮量硝化棉脱硝反应的微分动力学方程。
The denitration kinetics of the highly nitrated nitrocellulose (HNNC) containing 14.14% of nitrogen was studied by means of the thermal technique of solid reaction cell in situ in conjunction with rapid scan Fourier transform infrared spectroscopy (RSFT IR) for measuring the condensed phase decomposition products in real time. The kinetic parameters such as activiation energy and pre exponential factor of the denitration reaction were computerized by using the modified Coats Redfern method. On the basis of the results obtained, a differential knietic equation of describing the denitration reaction of HNNC in the temperature range 403～465K was proposed.
