【摘要】 以Ce4 + /Ce3 + 为氧化还原体系 ,以硫酸为支持电解质 ,采用槽外法研究了侧链芳烃的选择性间接电氧化。得出Ce3 -转化为Ce4 -最佳电解条件 :电流密度 0 .0 1A/cm2 ;硫酸浓度 ,0 .3mol/L;亚铈浓度 ,0 .5mol/L;通过电量 2F/mol(F为理论电量 )。电解生成的Ce4 + 氧化芳烃生成相应的醛、酮 ,反应具有选择性好、产率高、无污染等优点。更多还原

【Abstract】 paper describes the indirect electrooxidation of the side chain of aromatic compornds in a Ce(IV)/Ce(Ⅲ) redox system,Using sulfuric acid as the support eletrolyte.The optimum Conditions for the eletrolysis are:Current densit 0.2A/20cm 2;Concentration of sulfuric acid; 3mol/l;concentration of cerous nitrate,0.5mol/l electroquantity,2F/mol.Aromatic compounds Can be oxidized to carbonyl compounds by electrolysix-generated Ce(IV)without deep oxidation.The reaction has the following qdvantages:farourable seletivity,higt yield,nonpollution and economy.更多还原
