| 摘 要： | 使用加速量热仪(ARC)研究硝酸异辛酯(EHN)的热分解,得到热分解温度随时间的变化曲线,自放热速率、分解压力随温度的变化曲线以及分解压力随升温速率的变化曲线。分析在绝热条件下硝酸异辛酯的热分解反应动力学和热分解过程,计算表观活化能、指前因子和反应热等参数。根据绝热热分解的起始温度和反应热数据,给出硝酸异辛酯在反应危险度等级中的分类,并计算在75℃时的反应风险指数。

| Abstract: | The thermal decomposition of 2-ethylhexyl nitrate(EHN) was investigated using an adiabatic calorimeter called ARC.The curves of thermal decomposition temperature versus time,self-heating rate versus temperature,pressure versus temperature,and pressure versus self-heating rate were obtained.The thermolysis kinetics and decomposition process under adiabatic condition were analyzed,and kinetics parameters such as apparent activation energy,pre-exponential factor and reaction heat were calculated.According to its onset temperature(T onset) and heat of reaction,the hazard classification of EHN in thermal reactivity was obtained.The reactivity risk index(RRI) at 75℃ of EHN was also gained. |
