摘要
Two approaches (discriminating (1) and isoconversional (2)) to the evaluation of Arrhenius parameters for the thermal decomposition of solids under nonisothermal conditions are investigated and applied to both modeled and experimental data: Approach (1) allows only for the detection of an isokinetic relationship (IKR) but not for unambiguously estimating its parameters and approach (2) makes it possible not only to detect an IKR but also to determine its parameters. These may in turn be used to obtain information about the actual reaction pathway of the thermally induced process. The thermal decomposition of tetranuclear Cu(II) complexes with various ligands is used as an experimental example.
