本文用光谱电化学法研究了Ｎ，Ｎ－二甲基对苯二胺的电氧化反应及其随后不可逆均相水解反应，并用两种不同方法处理实验数据，测定了不同ｐＨ下的水解反应速率常数． In this paper, the electrochemical oxidation of N, N-dimethyl-p-phenylenediamine and its subsequent irreversible homogeneous hydrolysis were studied by means of spectral electrochemical method. The experimental data were processed by two different methods. The hydrolysis reaction rate constant.
