ELECTROCHEMICAL PREPARATION OF SODIUM CHLORATE FROM AQUEOUS SODIUM CHLORIDE.

A detailed study has been made of the electrolytic production of chlorate by the electrolysis of sodium chloride solution. Data are given in respect of the influence on the current efficiency of chlorate formation of the following factors : the temperature, the separation and disposition of the electrodes, the electrolyte concentration, the current density and addition agents. Influence of sun light and superimposition of A.C. during the electrolysis have also been investigated. A general theory of chlorate formation, electrochemically, is discussed
