摘　　要：在无隔膜电解槽中采用石墨电极,以稀HNO3为介质,Ce4+/Ce3+为氧化还原媒质,间接电氧化氟代甲苯法合成了邻(间、对)氟代苯甲醛。通过实验,得到了电解最佳条件,电流效率达到62%,氟代苯甲醛收率80%。O-（m-, p-） Fluorobenzaldehydes were synthesized by indirect electronic oxidation using diluted nitric acid as the medium and Ce^4＋/Ce^3＋ as the redox mediator. In the optimum conditions, the current efficiency was 62%, and the yield of fluorobenzaldehydes was 80%. Electrolysis was carried out in an undivided cell using graphite as electrodes.
