摘要: 本文应用电化学方法、顺磁共振一电化学技术、光谱电化学三种方法洋细研究了酚红在碱性(四丁基氢氧化铵)二甲亚砜(DMSO)溶液中的电化学还原行为, 确定了中间产物自由基, 并拟定了该自由基的结构, 提出了后续化学反应的决定步骤为歧化反应的EC机理。

Abstract: Electrochemical methods, ESR-Electrochemical methods and Spectroelectrochemical methods have been used to make a detailed study of the electroreduction of phenol red in alkaline DMSO with tetrabutyl ammonium hydroxide as supporting electrolyte. It was found that the free radical thus generated was consumed through a second order disproportionation reaction.
