摘要: 本文根据热动力学的基础理论, 讨论了等浓度二级反应的无量纲参数法, 并用以研究了苯甲酸乙酯皂化反应的热动力学。实验测得的速度常数在误差范围内与文献值很好符合。

Abstract: On the theoretical basis of thermokinetics proposed in reference, a for- mula for the method of dimesionless parameters for second order reactions with equal concentrations was derived. The values of relevant functions of dimesionless parameters were calculated. The properties of the function were discussed. And a functional table needed for calculating the rate constants of reaction was listed.
This method was then used to study the saponification of ethyl benzoate in “50%” aqueous alcohol solvent at 25.0 ℃ and 40.0 ℃. The thermographic cuve of this reactions was recorded. The rate constants of this reaction calculated with this method are in agreement with values in the literature.
Thus, the validity of this method and its theoretical basis should be proved.
