✦ Synopsis

Basic problems of kinetic processing of nonisothermal data ascertained from thermal analysis measurements can be solved by isoconversional methods Analysis of the dependence of the activation energy on conversion often permits the identification of the kinetic scheme for the process This dependence may also be used to solve applied kinetic problems related to predicting the behavior of a substance outside the range of experimental temperatures Methods for using this dependence for evaluating both the preexponential factor and the reaction model, as well as for detecting isokinetic relationships, have been discussed. Because all of these operations have a common origin in computing the dependence of the activation energy on conversion, isoconversional methods may be considered as a basis of a unified approach to kinetic processing of nonisothermal data @
