【Abstract】 The cell structure of p methoxybenzaldehyde by the indirect electrosynthesis using ceric/cerous as electrolytic medium was studied. The results indicated that electrolytic yield and current efficiency in an electrolytic cell with a diaphragm were higher than those in electrolytic cell without a diaphragm. Cell voltage in an electrolytic cell without a diaphragm was 0.85?V lower than that in an electrolytic cell with a diaphragm. By control of the area ratio of cathode and anode, Ce 4+ reduction on cathode was decreased in an electrolytic cell without a diaphragm. Power consumption in an electrolytic cell without a diaphragm was 70.6?kW·h/t fewer than that in an electrolytic cell with diaphragm, and on electrosynthesis of p methoxybenzaldehyde it was 590?kW·h/t fewer than that in an electrolytic cell with diaphragm.更多还原
