Production of sodium chlorate is by electrolysis of an acidified sodium chloride solution. Purified brine is acidified with hydrochloric acid and sodium dichromate is added to improve cell efficiency and reduce electrode corrosion. The acidified brine is fed to a bank of electrolytic cells. production sodium chlorate chlorate sodium Prior art date 1986-03-27 Application number PT8457087A Other languages Portuguese (pt) Other versions PT84570B (en Inventor John E Burkell Ian H Warren Original Assignee Canadian Ind Priority date (The priority date is an assumption and is not a legal conclusion. ABSTRACT OF THE DISCLOSURE A process for the production of sodium chlorate comprising electrolyzing an aqueous sodium chloride solution in a di-aphragmless sodium chlorate cell, characterized in Sodium Chlorate is produced when an acid solution of sodium chloride is heated and electrolyzed and then crystallized. Sodium Chlorate is manufactured by the electrolytic oxidation of Sodium Chloride using Titanium substrate anodes. A process for the production of sodium chlorate comprising electrolyzing an aqueous sodium chloride solution in a diaphragmless sodium chlorate cell, characterized in that an aqueous sodium chloride solution containing, as impurities, calcium, magnesium, barium and the like is contacted with a chelating ion exchange resin to remove the impurities and the resulting saline solution is supplied into a diaphragmless sodium chlorate cell, thereby enabling sodium chlorate to be produced at a Sodium chlorate is produced from two commonly found raw materials: salt (NaCl, sodium chloride) and water (H2O) along with the use of large amounts of electrical energy.

2008-07-09 Effects of sodium chlorate on toxin production by Escherichia coli O157:H7. Current Issues in Intestinal Microbiology. 5:19-22. Interpretive Summary: Escherichia coli O157:H7 is a food borne pathogenic bacterium that is killed by the addition of sodium chlorate. Sodium chlorate’s main use is the generation of chlorine dioxide for pulp bleaching.

The manufacturing process involves the electrolysis of an acidified sodium chloride solution in a specially designed electrochemical cell. Sodium chlorate is the raw material for chlorine dioxide (ClO2), which is produced on-site at the pulp mills and it is the primary bleaching agent for kraft pulp. “The consumption of bleaching chemicals is increasing due to the recent pulp mill expansions and the announced greenfield projects in the Nordics. Process for the production of sodium chlorate by the electrolysis of sodium chloride contaminated with sodium sulphate wherein the sulphate concentration in the system is kept below a pre-selected level.
