【摘要】 列举了基辛格方程的理论分析和发展,认为1957年提出的基辛格方程仅适用于n级反应。经过Xiang Gao、David Dollimore等的工作,Kissinger方程已经发展成了一个近乎完美的无模式微分动力学方程。对于大多数反应模式,当E/RT>10.7时活化能的相对误差小于或等于5%,但是指前因子不能由Kissinger直线的截距求出。以Ozawa法所求得的活化能作真值,用Kissinger法求得的硝基胍热分解活化能的相对误差为0.66%,小于5%。更多还原

【Abstract】 The theoretical analysis and development of Kissinger equation were cited.Considering that the Kissinger equation proposed in 1957is only applied to nth order reaction.This equation has been developed into a perfect model-free differential kinetic one via the works of Xiang Gao and David Dollimore et al.The relative error of activation energy is less than or equal to 5% when E/RT>10.7for most reaction models,but the pre-exponential factor Acan not be solved directly from the line intercept of the Kissinger straight line.In this study,using activation energy calculated by Ozawa as theoretical value,the relative error of activation energy calculated by Kissinger method for thermal decomposition reaction of nitro guanidine is 0.66%,which is less than 5%.更多还原
