| 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. |
