    摘要: In various aspects and embodiments the invention provides a method for preparing a metal periodate by anodic oxidation of a metal iodide in an electrolysis cell comprising one or more anodes and one or more cathodes, characterised in that the one or more anodes are carbon-comprising electrodes. In certain embodiments the method is characterised in that the one or more anodes comprise a diamond layer doped with one or more IUPAC group 13, 15 or 16 elements of the periodic table.

    摘要: A method of producing ammonium persulfate by electrolyzing ammonium sulfate is characterized in that an ammonium sulfate aqueous solution is supplied as an anode-side feedstock, a solution containing less than 1.0 mol of acid-derived acid dissociable hydrogen ions per 1.0 mol of amount of charge transfer is supplied as a cathode-side feedstock, and electrolysis is performed to produce ammonium persulfate on the anode side and at least ammonia on the cathode side. Since ammonium sulfate not dependent upon the ammonium sulfate produced within the system can be used as a main feedstock, the method is industrially advantageous and, further, because of an electrolytic method, the method enables the coproduction not only of ammonium persulfate but also of valuable materials such as ammonia and hydrogen and, furthermore, enables the production of ammonium persulfate at a high current efficiency.

    摘要: An industrially useful peroxo-carbonate is electrolytically produced using, as a raw material, carbon dioxide that is inexpensive and easily available. A process of producing a peroxo-carbonate, includes feeding a carbon dioxide gas into an electrolytic cell having a gas diffusion anode and a cathode, or feeding a liquid having a carbon dioxide gas dissolved therein into an electrolytic cell having an anode and a cathode, and electrolytically converting the carbon dioxide gas into a peroxo-carbonate. By properly setting up electrolytic conditions such as electrodes, a useful peroxo-carbonate can be produced with high current efficiency using inexpensive carbon dioxide as the raw material.
