Manufacture of sodium Chlorine dioxide can be produced from sodium chlorate using different reducing agents like hydrogen peroxide, sulfur dioxide, methanol, and hydrochloric acid. The starting material is NaCl (Sodium Chloride or common salt). Sodium Chlorate is very soluble. About 330 grams NaCl per liter of water is the starting solution. A. Sodium chlorate's main use is the generation of chlorine dioxide for pulp bleaching. Pulp is a key ingredient in the production of paper and cardboard. Sodium Jan 17, 2000 Technology.

When used for the production of chlorine dioxide the sodium chlorate is reacted commonly with sulphuric acid to produce chlorine dioxide, chlorine and sodium sulphate. Usually a pH of about in the feed is satisfactory. The feed to the cell comprises 1080 pounds per hour of sodium chlorate, 640. poundsper'hour of sodium chloride and 2640 pounds per hour of water. Separating the sodium chlorate from the remaining sodium chloride and getting it pure is the tedious part. Easiest is to can dump a lot of salt in your cell, once the reaction progresses and sodium chlorate saturates, it will start to crystalise out. If you don't get the conditions correct, you can easily produce sodium hypochlorite.

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.

ABSTRACT "Production of Sodium Chlorate" Process for the production of sodium chlorate by the electrolysis of sodium chloride contaminated with sodium sulphate wherein the sulphate concentration in
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. The manufacturing process involves the electrolysis of an acidified sodium chloride solution in a specially designed electrochemical cell. 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. The primary non-pesticidal use for sodium chlorate is as a precursor in chlorine dioxide generation through a closed system to bleach wood pulp/paper. The pesticidal uses of sodium chlorate, including the agricultural uses as a defoliant/desiccant, are a small percentage (approximately 2%) of the total sodium chlorate used in the United States.
