Eka SC  Industrially, sodium chlorate is produced by the electrolysis of a hot sodium chloride solution: NaCl + 3 H 2 O → NaClO 3 + 3 H 2 This reaction progresses in heat (at least 70 °C), and controlled pH . 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.

All perchlorate compounds are created commercially by the oxidation of solutions of sodium chlorate by electrolysis. Sodium chlorate is produced by the electrolysis of brine. This energy-intensive, multistage process is run in closed loop plants from which emissions are kept to a minimum. This requires maintaining good chemical balances and running with precise control. 2007-01-01 In general, sodium chlorate is produced commercially by electrolysis of an aqueous solution of sodium chloride in an electrolytic cell.

The industrial production of sodium chlorate is one of the largest industrial electrochemical processes both in terms of annual production and energy consumption. Since it is the dominantly applied reagent for wood pulp bleaching, the demand for sodium chlorate is still on the rise with an ever increasing use of different paper products. This paper presents a novel cleaner production process for producing sodium chlorite by reducing sodium chlorate with hydrogen peroxide. In the new process, chlorine dioxide is generated by reducing chlorate ions with hydrogen peroxide in the presence of sulfuric acid: it then reacts with aqueous sodium hydroxide solution and hydrogen peroxide to produce sodium chlorite. Electrochemical production of alkaline hydrogen peroxide solution by reducing oxygen on a cathode and simultaneous production of sodium chlorate is disclosed in E. E. Kalu and C. Oloman, "Simultaneous electrosynthesis of alkaline hydrogen peroxide and sodium chlorate", Journal of Applied Electrochemistry 20 (1990), 932-940. food packaging (sodium chlorite) and as a defoliant, desiccant and fungicide in agriculture (sodium chlorate) (US EPA, 1983; CMA, 1989; US FDA, 1990). 2.3 Estimated total exposure and relative contribution of drinking-water The major route of environmental exposure to chlorine dioxide, chlorite and chlorate is through drinking-water.
