Sodium chlorate The Chloralkali process is an industrial process for the electrolytic production of sodium hydroxide and chlorine. It can also be synthesized by passing chlorine gas through a solution of sodium hydroxide. It is then purified by crystallization. The main commercial use for sodium chlorate is for making chlorine dioxide (ClO). The largest application of ClO, which accounts for about 95% of the use of chlorate, is in bleaching of pulp. All perchlorate compounds are produced industrially by the oxidation of solutions of sodium chlorate by electrolysis. Sodium chlorate is used as a non-selective herbicide. It is considered phytotoxic to all
