摘要
运用循环伏安法和现场红外反射光谱电化学技术,研究了0.2mol/LKCl水溶液中对甲氨基苯酚在铂电极上的电氧化还原过程.循环伏安扫描和现场红外反射吸收光谱结果表明:对甲氨基苯酚的电氧化还原过程中有两个电子和两个质子发生转移,对甲氨基苯酚首先氧化生成对甲亚胺基苯醌,然后其氧化产物发生不可逆水解反应生成对苯醌和甲氨.
The electrochemical redox reaction of p-methylaminophenol on platinum electrode in 0.2 mol/L KC1 solution was investigated by cyclic voltammetry and in situ reflection absorption Fourier transform infrared spectroscopy (FTIRS). The results show that two electrons and protons were transferred during the redox process of p-methylaminophenol. The electrochemical oxidation of p-methylaminophenol yields p-N-methylobenzoquinoeimin intermediate at first. And then the p-N-methylobenzoquinoeimin further undergoes irreversible hydrolysis to yield p-benzoquinone and methylamine.
