Electrooxidation of selected phenylethers was investigated (2-phenoxyethanol, anisole, o-nitrophenyl octyl ether, diphenylether, fenoxycarb) on platinum and glassy carbon electrodes. The chosen solvents were acetonitrile, dimethyl sulphoxide, 1-propanol and mesityl oxide. In acetonitrile, at around 2 V characteristic voltammetric peaks appeared for all compounds. In dimethyl sulphoxide and 1-propanol, no relevant peak appeared due to the high overlapping with solvent electrooxidation. During anodic oxidation of o-nitrophenyl octyl ether and fenoxycarb, a bimolecular reaction takes place predominantly. In mesityl oxide due to its unsaturated bond, identical behaviour was observed for majority of compounds and the differences between the two electrodes are also highlighted in the surface studies. The images made with the aid of an optical microscope showed the formation of islands of products for each substrate after deposition from mesityl oxide.

铂和玻璃碳电极上非水溶剂中苯醚的阳极行为研究

在铂和玻璃碳电极上研究了选定的苯醚(2-苯氧基乙醇,苯甲醚,硝基苯基辛基醚,二苯醚,苯氧威)的电氧化。选择的溶剂是乙腈,二甲基亚砜,1-丙醇和异丁烯醇。在乙腈中,所有化合物均在2 V左右出现特征伏安峰。在二甲基亚砜和1-丙醇中,由于与溶剂电氧化的高度重叠,没有出现相关峰。o的阳极氧化过程中-硝基苯基辛基醚和苯氧威,双分子反应主要发生。在异亚丙基丙酮中,由于其不饱和键,大多数化合物观察到相同的行为,并且在表面研究中还突出了两个电极之间的差异。借助光学显微镜拍摄的图像显示了从异丁烯氧化物沉积后,每种基质形成的产品岛。
