Abstract
For several years an electrolytic process for the production of potassium perchlorate has been operated at Claremore, Oklahoma, by the Cardox Corporation of Chicago. This paper describes the process and the electrolytic cells. Sodium chloride is oxidized to sodium chlorate in one set of cells, and the sodium chlorate is oxidized to sodium perchlorate in a second set of cells. The sodium perchlorate is then reacted with potassium chloride to form potassium perchlorate and sodium chloride, and the latter salt is recycled to the chlorate cells. All operations are conducted batchwise. A graphite anode‐steel cathode cell is used for the conversion of chloride to chlorate, and a platinum‐clad anode‐steel cathode cell is used to change chlorate to perchlorate. Construction and operating data are presented for both cells.
