根据热动力学基础理论,本文首次建立和讨论了等浓度三级反应的无量纲参数法.测定了20℃时环氧氯丙烷与氢溴酸反应的速率常数,实验的重现性很好,计算此反应的速率常数在误差范围内与文献值相符合.证明了等浓度三级反应无纲参数法的正确性,拓宽了无量纲参数法的应用范围.

The method of dimensionless parameter for third-order reactions is established using thermokinetics. The rate constant of the reaction for epichlorohydrin with HBr is measured at 20? The reproducibility of experimental results is very good, and calculated rate constant was in agreement with the lit. value.
