Description
Summary:The potentialities of the proposed software, which is based on the isoconversion method of calculating the Arrhenius parameters, are compared with software of the Du Pont and Mettler thermoanalysers. Calculations by the model DSC curves for a process involving two parallel independent reactions have shown that the software of the thermoanalysers does not provide reliable information about the kinetics of complex processes. The proposed software makes it possible to establish the complex character of a process and its type, to evaluate the activation energies of parallel reactions and to predict the kinetics of its proceeding outside the experimental temperature range.
