摘　　要：为研究气固叠氮化反应过程,采用等温热重(TG)法,测试叠氮化钠、硬脂酸以及铜粉混合物在120℃、130℃、140℃下的热重曲线,对气体释放及叠氮化过程进行表征,根据不同温度下的TG数据进行动力学计算,推算气固叠氮化反应的反应机理方程。研究表明:叠氮酸生成反应的机理函数为26号,Mampel Power法则,纳米铜粉叠氮化反应的机理函数为29号,反应机理为收缩球体(体积),相边界反应。本研究为气固原位叠氮化反应的过程研究提供理论和技术支撑。In this paper,isothermal TG was used to study the gas-solid azidation reaction,in which TG curves of the mixture of stearic acid,sodium azide and Cu nano particls were measured at 120℃,130℃,140℃.The TG curves at different temperature were used to dynamic calculation,in order to predict the mechanism equation of gas-solid azidation reaction.The results showed that the mechanism function of hydrazoic acid generation reaction is No.26 Mampel Power’s law,and that of copper azide reaction is No.29 shrinking sphere phase-side reaction mechanism.This research provides theoretical and technical support for the process study of gas-solid azidation reaction.
