摘要
根椐热动力学基本理论,推导出了热导式量热计测量的连续一级反应的热谱曲线的动力学解析方程,并推出了连续一级反应热动力学的自函数递推方程,由此建立了一种研究连续一级反应的热动力学新方法--自函数回归法.通过对丁二酸二乙酯和邻苯二甲酸二乙酯的皂化反应的热谱曲线分析,验证了自函数回归法的正确性.
According to the theory of thermokinetics, the equation of thermoanalytical curve for consecutive first - order reaction occurred in conduction calorimeter has been derived and a novel thermokinetic research method-the self - function regression method for consecutive first - order reactions, which can be used to determine the rate constants of two steps simultaneously is proposed in this research. In order to test the validity of this method, saponifications of diethyl phthalate and diethyl succinate in aqueous ethanol solvent were studied. The rate constants calculated using this method are in good agreement with those in the literatures. Therefore, the self - function regression method for consecutive first - order reactions is believed to be correct.
