摘　　要：研究了以茴香脑为原料,用Ce4+/Ce3+为氧化还原媒质,选择性间接电氧化合成茴香醛。用正交实验和单因素实验研究了Ce3+电解氧化成Ce4+的反应条件,并优化出了最佳电解条件:电解液中Ce3+的浓度为0.3mol.L-1,H2SO4浓度为1mol.L-1,电流密度为80mA/6 cm2,电解温度为30℃,阴阳极面积比为1∶6,通电量1.5F.mol-1。The indirect selective electrochemical oxidation of anethole to. anisaldehyde with Ce^4＋/Ce^3＋ as redox mediator system was studied in this thesis. The optimization of electrooxidation conditions was carried out by reviewing the effects of factors on the yield of Ce^4＋ through orthogonal tests and single - factor tests. The optimized conditionds are as fellow： the electrolyte solution containing 1mol·L^-1 H2SO4 ＋ 0. 15mol·L^-1 Ce2（SO4）3, giving the electroquantity of 1.5F·mol^-1 ,using the current density of 14mA · cm^-2 and the area ratio of cathode to antode 1 ： 6 at the temperature of 30℃.
