    Study on the Compensation Effect for a Series of Related Reactions in Thermal Analysis

    • 摘要: 根据热分析谱图峰顶的数学特征与Coats-Redfern方程,推得在一定实验条件下,在系列相关反应中,若峰顶温度相接近,则各反应的表观活化能E与指前因子A之间存在着有动力学意义的补偿效应,即lnA=aE+b。并经系列含水硫酸盐脱水反应实验验证。

       

      Abstract: According to the mathematical character of the peak of thermal analysis curve and by using of Coats-Redfern equation,the compensation effect having kinetics significance was discovered for a series of related reactions,if the peak tempertures of those reactions are close each other at certain expcriment conditions.The validity Was confirmed by dehydration reactions of hydrated sulfates.
