Studies on the Cell Structure of p-methoxybenzaldehyde by the Electrosynthesis
摘要/Abstract
研究了Ce4+/Ce3+做氧化媒质间接电合成对甲氧基苯甲醛的槽型结构.结果表明,隔膜电解槽与无隔膜电解槽相比,电解收率和电流效率较高;在无隔膜电解槽内,槽压低0.85V,通过调节阴阳极面积比,减少在阳极区Ce3+电解氧化生成的Ce4+在阴极区被还原为Ce3+,电耗比隔膜电解槽减少70.6kW·h/t,生产对甲氧基苯甲醛电耗减少590kW·h/t.
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 0.85V lower than that in an electrolytic cell with a diaphragm. By control of the area ratio of cathode and anode, Ce4+ reduction on cathode was decreased in an electrolytic cell without a diaphragm. Power consumption in an electrolytic cell without a diaphragm was 70.6kW·h/t fewer than that in an electrolytic cell with diaphragm, and on electrosynthesis of p-methoxybenzaldehyde it was 590kW·h/t fewer than that in an electrolytic cell with diaphragm.
