A method of electrochemical synthesis, and specifically relates to a green production process for an iodate. The process includes preparing lithium iodate by means of an electrolysis method, and then reacting the prepared lithium iodate with an iodide to prepare the iodate. In the process, a mother liquor is recycled, no effluent waste is produced, a product yield is high, and the generation of a large amount of waste salt is avoided. The process is green and environmentally friendly. During the synthesis process of preparing lithium iodate by means of an electrolysis method, using a clean electrolysis process does not require the addition of an oxidant and other additional original auxiliary materials as required by a chemical method, the original auxiliary materials are simple, and a produced iodate product has a high quality.

A process for electrochemical preparation of sodium alkoxide is performed in an electrolysis cell having three chambers, wherein the middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to sodium ions, and from the anode chamber by a diffusion barrier. The geometry of the electrolysis cell protects the solid-state electrolyte permeable to sodium ions from acidic destruction by the pH of the anolyte that falls in the course of electrolysis. The anolyte used in the process is a brine also comprising carbonates and/or hydrogencarbonates, as well as NaCl. The process solves the problem that CO.sub.2 from these carbonates and/or hydrogencarbonates forms in the electrolysis cell during the electrolysis of this brine obtained from pretreatment. The process prevents the formation of a gas bubble in the electrolysis cell that disrupts electrolysis and reduces the contamination of the chlorine with CO.sub.2.
