【摘要】 以Nafion417作隔膜,Pb-PbO2作阳极,Pb作阴极,电解氧化Cr(Ⅲ)为Cr(Ⅵ),然后以Cr(Ⅵ)为氧化媒质,氧化间甲基二苯醚为间苯氧基苯甲酸.研究了在Nafion417隔膜槽中影响Cr(Ⅲ)电氧化的因素,并进一步探究优化电合成间苯氧基苯甲酸的工艺条件.更多还原

【Abstract】 The m-phenoxy benzoic acid was synthesized by oxidation m-phenoxy toluene using Cr（Ⅵ）as oxidation media, which was prepared by electrolysis oxidation of Cr（Ⅲ）in the electrochemical bath using Nafion 417 as a diaphragm, Pb-PbO₂ as an anode and Pb as cathode. The effect factors on the electrochemical oxidation of Cr（Ⅲ）to Cr（Ⅵ）in this electrolysis were studied. Furthermore, the optimal conditions for electronic synthesis of m-phenoxy benzoic acid were also discussed.更多还原
