摘要
本文采用高压差热分析技术和高压原位傅立叶变换红外光谱检测技术研究了硝化甘油在压力下的热分解动力学及机理,结果表明:硝化甘油在压力下的热分解速度可以由自催化动力学方程来描述;硝化甘油的热分解通过两种反应进行,一种是硝化甘油本身的热分解反应,另一种是热分解产物NO_2与它的反应,NO_2通过夺氢反应自催化了硝化甘油的热分解,压力加快了这种夺氢反应的进行,从而加速了硝化甘油的热分解,据此,本文还提出了硝化甘油在压力下的自催化热分解机理。
The thermal decomposition dynamics and mechanism of nitro- glycerin under pressure has been studied by high pressuse differ- ential thermal analysis technique and high pressure in-situ Fou- rier transform infrared spectroscopy technique. The results show that the thermal decomposition of nitroglycerin under pressure may be described by autocatalytic rate law. The No_2 autocataly- zes the thermal decomposition of nitroglycerin by reaction with hydrogen, pressure accelerates the hydrogen transfer reacfion, So it speeds up the thermal decomposition of nitroglycerin. On this basis, the autocatalytic mechanism for the thermal decomposition of nitroglycerin is proposed.
