Thermal Analysis Activation Energy Of The Solution And Analysis

This paper analyzes and studies in depth the classical kinetics method in the thermal analysis Ozawa method, Friedman method , Kissinger method and the new development thermal analysis kinetics method Integral by step equation method and Simultaneous thermal analysis method, and evaluates the advantages and disadvantages s of various methods and applicable scope; Secondly, these methods were employed to compute the activation energy of two classical reactions (the degradation of Polyamide(PA6) and the decomposition of CaC₂O₄ · H₂O ) . The result of study shows : Sometimes Ozawa method and Kissinger method are right, and sometimes in larger error; Friedman method although adopts different computing method, the result of the activation energy is larger than Integral by step equation method sec; Integral by step equation method is the accurate method to compute the activation energy regardless of the conversion function, but it can't get the reaction order; Simultaneous thermal analysis method is a relatively accurate method, it can not only compute the activation energy but also get reaction order and the conversion function at the same time.
