【摘要】 采用 TG- DTG- DTA热分析技术研究了 N,N’-双 (3-氨丙基 )草酰胺合胴 ( )配合物在动态空气气氛中的热行为 ;用微分法 (Achar法 )和积分法 (Coats- Redfen法 )协同处理非等温 TG数据 ,通过对比热分解动力学参数 E和 ln A,提出了配合物第一阶段热分解动力学方程 :dα/ dt =Ae- E/ RT (1-α ) 2 及第二阶段热分解动力学方程 :dα/ dt=Ae- E/ RT(1-α) ;并由动力学补偿效应获得了 E和 ln A的数学表达式

【Abstract】 The thermal decomposition of copper(Ⅱ) complex with N,N′ bis(3 aminopropyl)oxamide and non isothermal kinetics under dynamic air atmosphere were studied by TG, DTG and DTA technique. The non isothermal kinetics data were analyzed by means of the Achar method and the Coats Redfen method. The possible kinetic model function was suggested by comparison of the kinetic parameters. The kinetic equation for first stage can be cxpressed as:dα/dt=Ae -E/RT (l-α) 2. The second stage is: dα/dt=Ae -E/RT (l-α). The mathematical expressions of E and lnA were derived from the kinetic compensation effects.
