Electrochemical Manufacture of Perchlorates

Manufacture of different metal perchlorates starts from sodium perchlorate which is, because of its high solubility, easy to prepare electrochemically. Sodium perchlorate is, however, not much used commercially, as it is deliquescent, yet it is an intermediary product for the manufacture of other perchlorates. 

Sodium perchlorate is prepared by electrolysis of concentrated solutions of sodium chlorate in cells without diaphragms using platinum anodes and iron cathodes. Electrolysis is continued until some 95 per cent of the initial chlorate
