环己醇电化学氧化的研究

本文采用了旋转圆盘电极、电位阶跃、循环伏安及微分电容血线等实验手段对环己醇电化学氧化的电极过程动力学性质进行了研究。实验测出了环已醇的扩散系数、电极过程中的传递系数、电子转移数及不同电位下的反应速度常数等动力学参数,并推测了反应机理。实验分析表明环己醇电化学氧化成环已酮是一个完全不可逆的电极过程。

STUDY ON THE ELECTRO—OXIDATION OF CYCLOHEXANOL

In this paper, we use cyclic voltammetrv step methods, rotaing disk electrode and differential capacitance methods to inquire into the kinetic problems of the electro-oxidational process of cyclohexanol. Through the experiments, we have obtained the diffusion coefficient of cyclohexanol, transfer coefficient of the electrode process, and the reaction rate constant at different supplied potential, and we also speculated the mechanism of this process. The experiments show clear that the electrode process of electro-oxidating cyclohexanol to cyclohexanone is a totally irreversible and the overall electrode process is not very fast.
