在硫酸介质中铂阳极上Ag~+对于Cr~(3+)和Mn~(2+)的氧化有一种很有效的催化作用.在Ag~+-e→Ag~(2+)氧化峰的电位处,Mn(Ⅱ)和Cr(Ⅲ)放催化氧化的电流效率皆高,其电流为为Mn~(2+)、Cr~(3+)离子向电极表面的扩散过程所控制.选择适当的条件,Mn(Ⅱ)被催化氧化的产物可以是Mn~(3+)、MnO_2和MnO_4~-.在相转移催化剂的存在下,这—Cr_(2)O_7~(2-)的阳极再生过程曾和有机溶剂中进行的有机物氧化过程联用,结果表明苯甲醇向苯甲醛、蒽向蒽醌的转化率是高的.
Ag ~ + can catalyze the oxidation of Cr ~ (3+) and Mn ~ (2+) on the anode of platinum sulfate solution in sulfuric acid medium.At Ag ~ + -e → Ag 2+ oxidation peak At the potential, the current efficiency of Mn (Ⅱ) and Cr (Ⅲ) in catalytic oxidation is high, and the current is controlled by the diffusion process of Mn 2+ and Cr 3+ ions to the electrode surface. , The products of Mn (Ⅱ) catalyzed oxidation can be Mn ~ (3 +), MnO_2 and MnO_4 ~ -. In the presence of phase transfer catalyst, the anode of this Cr_ (2) O_7 ~ The process has been combined with the oxidation of organic compounds in organic solvents. The results show that the conversion of benzyl alcohol to benzaldehyde and anthracene to anthraquinone is high.
