摘　　要：用热重—差热分析法对阻燃剂四溴苯酐的热分解过程进行了动力学研究。结果表明:四溴苯酐的热分解过程分两步进行。采用Doyle- Ozawa积分法和Achar -Brindley- Sharp- Wendworth微分法对两步热分解过程分别进行分析,在30种机理函数中进行筛选,得到了四溴苯酐的两步热分解的最概然机理及动力学特性参数。Thermograrimetry-differential analysis was used to the study of the thermal decomposition dynamics of tetrabromophthalic anhydride. The results showed that the thermal decomposition of tetrabromophthalic anhydride proceeded in two stages. The two thermodecompo- sition processes were analyzed by Doyle-Ozawa integration method and Achar-Brindley-Sharp-Wendworth differentiation method. Selected from 30 mechanisms, the most probable mechanism function and the kinetic parameters were obtained.
