自函数回归法: 连续一级反应的热动力学研究

根据热动力学基本原理,推导出了连续一级反应热动力学自函数递推方程,从而建立了一种新的连续一级反应的热动力学研究法---自函数回归法.应用该法分别研究了丁二酸二乙酯和邻苯二甲酸二乙酯皂化反应的热动力学。

Self --function regression method : Studies on thenmokinetics of consecutive First-Order reactions

According to the theoretical basis of thermokinetics, a self - function recursion equation of irreversible consecutive first - order reactions has been derived and a novel thermokinetic research method--self - function regression method for consecutive first - order reactions, which can be used todetermine the rate constants of two steps stimultaneously, has been proposed in this paper. In order to test the validity of this method, the saponifications of diethyl phthalate and diethyl succinate in aqueous ethanol solvent have been studied. The rate constants calculated with this method are in agreement with those published in literature, and therefore, the self- function regression method for consecutive first -order reactions is believed to be correct.
