摘　　要：根据热动力学基本理论 ,导出了平行一级和二级反应的热动力学方程 ,建立了热谱解析平行的一级和二级反应动力学参数的数学模型 。On the basis of thermokinetic theories, the thermokinetic equation of parallel first and second order reactions has been derived, and the mathematical model to determine the kinetic parameters for parallel first and second order reactions from the same thermoanalytical curve has been established. In order to test the validity of this method, two simulated parallel reaction systems (saponifications of mixed esters in aqueous ethanol solvent) have been studied. The kinetic parameters calculated with this method are in agreement with those in the literature, therefore, the thermokinetic research method for parallel reactions proposed is believed to be correct.
