| 摘 要： | 在非等温条件下,改变升温速率对硫脲进行了热分解动力学方面的研究,并用微分Kissinger法和Ozawa法对硫脲的热重和热流曲线进行了动力学分析,得出硫脲热分解过程的动力学参数,硫脲异构化活化能为80 kJ/mol,硫氰酸胍生成反应的活化能为205 kJ/mol,实验结果与文献吻合。

| Abstract: | The paper investigated thermal decomposition kinetics of thiourea under non-isothermal condition.Kinetics parameters of thiourea were analyzed with the methods of Kissinger and Ozawa from TG and DSC curves.The activation energies of isomerization of thiourea was 80 kJ/mol,and the decomposition of guanidinium thiocyanate was 205 kJ/mol,and they were very identical with the literature results. |
