A number of 1145 sets of kinetic parameters derived in our earlier papers from TG curves have been worked up. The apparent activation energy and pre-exponential factor values have been found to obey a linear compensation law (isokinetic relation) if the thermal decomposition begins in the same temperature interval, irrespective of the nature of the chemical reaction. The isokinetic temperatureTi has been found to be very close to the mean value of the temperaturesT0.1 at which the conversion becomes equal to 0.1 and atTi the rate constant has been found to be approximately equal to 10−3s−1 in allT0.1 intervals investigated. It is concluded that the kinetic compensation effect observed in heterogeneous non isothermal TG kinetics is not a true one.
