| Abstract: | Indirect electrosynthesis of ochlorobenzaldehyde from ochlorotoluene was carried out using ceric/cerous in sulfuric acid as a mediator. The optimum conditions (temperature 348 K, surfactant concentration 1.4×10 -3～2.2×10 -3mol/L, sulfuric acid concentration 7.5 mol/L) were determined by orthogonal experiments and monofactor tests. The yield of ochlorobenzaldehyde reached 93.1% in the optimal experiment .The current efficiency was 89.46% and the electrolytic yield of Ce 4+ was 50.15% in the electrolytic experiments. |
