摘　　要：根据热动力学基本理论，建立了一种新的热动力学研究法——等浓度三级反应的双谱解析法，该法利用两张谱曲线的特征热谱数据ａ＊ｍ，Δｍ和ｔｍ使能以简单的数学形式求解化学反应速率常数．通过对环氧氯丙环开环反应的热动力学研究。Based on the fundamental theory of thermokinetics and kinetic equation of the third order reaction with equal concentrations,a novel thermokinetic research method for the third order reaction double thermoanalytical curve analytic method has been proposed.The method only needs characteristic data Δ m,a  m and t m of two thermoanalytical curves measured at different initial concentrations of reactant and conveniently calculates the rate constant.In order to test the validity of this method,the ring opening reactions of epichlorohydrin with HBr or HCl in aqueous solution have been studied at 20℃ and 30℃,respectively.The experimental results indicate that the double thermoanalytical curve analytic method is correct.
