摘要
This paper has studied the recycling of the oxidation mediator Mn(Ⅲ)/Mn(Ⅱ) and sulfuric acid solution in process of indirect electrosynthesis of benzaldehyde. Experimental resalts show that mis recycling may be realized When electrolysis and synthetic reaction are carried out in the same concentration of 60% H2SO4 separately, then there will be no waste discharged, energy consumption will be decreased and almost no current efficiency will be lossed during recycling process. The optimun current efficiency is 76%, yield of benzaldehyde is 64%.
