摘要
应用循环伏安和恒电位电解法研究了茴香醚在铂电极上直接电氧化行为.考查扫描速率、反应底物浓度、支持电解质和溶剂对该电氧化行为的影响.结果表明,茴香醚在铂电极上的氧化过程是不可逆的.在硫酸/丙酮溶液中,其响应峰电流最高,反应受扩散控制.经GC-MS检测,主要氧化产物为茴香醛,选择性为66.5%.
The direct electro-oxidation of anisole on Pt electrode was investigated by cyclic voltammery and constant potential electrolysis.The influences of scan rate,substrate concentration,supporting electrolyte and solvent were studied.The products of constant potential electrolysis were charactered by GC-MS.The results show that the electro-oxidation process of anisole was irreversible.In this research the sulfuric acid was the best supporting electrolytes and acetone was the best solvent.The process was controlled by diffusion.The main products were anisaldehyde,and the selectivity was up to 66.5% when using acetone as a solvent.
