Sodium chlorate Usage And Synthesis
Sodium chlorate (chemical formula: NAClO3) is an inorganic compound, appearing as white crystalline powder. It has an annual yield of several hundred million tons around the world. It has many applications. Its major commercial application is for the manufacture of chlorine dioxide which is used in bleaching of pulp. Sodium chlorate can also be used for the industrial manufacture of perchlorate compounds through electrolysis. It can also be used as a non-selective herbicide to control many kinds of plants such as morning glory, Canada thistle, Johnson grass and bamboo. In addition, it can also be used as a defoliant and desiccant. It is also used for the generation of chemical oxygen which is important for emergency oxygen generation in commercial aircraft. In industry, sodium chlorate is manufactured by the electrolysis of a hot sodium chloride solution. It is also useful for making inks, cosmetics, paper and leather.
Sodium chlorate is a white crystalline solid.
Sodium chlorate, NaCI03, is colorless,odorless crystals with a cooling, saline taste, is soluble in water and alcohol,but must not be triturated with any combustible substance. Derived by heating and electrolyzing a concentrated acid solution of sodium chloride so that the chlorate is crystallized out. Used as an oxidizing agent and bleach (especially to make chlorine dioxide)for paper pulps, ore processing, herbicide and defoliant, substitute for potassium chlorate (sodium chlorate is more soluble in water),matches,explosives, flares,and pyrotechnics, in the recovery of bromine from natural brines,leather tanning and finishing, textile mordant,and to make perchlorates.
It is oxidimetric reagent.
A sulfation biosynthesis inhibitor.
An oxidizer, like potassium chlorate, in manufacture of dyes; explosives and matches; dyeing and printing fabrics; tanning and finishing leather. Herbicide. Pharmaceutic aid (oxidizing agent).
ChEBI: An inorganic sodium salt that has chlorate as the counter-ion. An oxidising agent, it is used for bleaching paper and as a herbicide. It is also used in the manufacture of dyes, explosives and matches.
Sodium chlorate in a water solution is a clear colorless liquid. Sodium chlorate is noncombustible but Sodium chlorate can accelerate the burning of surrounding combustible materials. This can easily occur if the material should dry out. Contact with strong sulfuric acid may cause fires or explosions.
Air & Water Reactions
Soluble in water.
SODIUM CHLORATE decomposes upon heating forming O2; reacts with strong acids forming toxic and explosive ClO2; reacts with many substances [Handling Chemicals Safely 1980 p. 833]; metal chlorates are oxidants in the presence of strong acid; liberates explosive chlorine dioxide gas; heating a moist metal chlorate and a dibasic organic acid liberates chlorine dioxide and carbon dioxide; mixtures of perchlorates with sulfur or phosphorus are explosives [Bretherick 1979 p. 100]; mixtures of the chlorate with ammonium salts(ammonium thiosulfate), powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination of finely divided aluminum with finely divided bromates(also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium or zinc can explode by heat, percussion, and friction [Mellor 2:310 1946-47]. Sodium chlorate and arsenic trioxide form a spontaneously flammable mixture [Ellern 1968 p. 51]. Mixtures of organic material and more than 10% sodium chlorate are sufficiently combustible to be hazardous at low relative humidity. Mixtures of organic material such as charcoal, sugar, flour, or shellac and sodium chlorate may be ignited by friction or shock [Chem. Safety Data Sheet SD-42 1951].
Dangerous fire risk, strong oxidant, contact with organic materials may cause fire.
Contact causes irritation of eyes and skin. INGESTION: May cause nausea, vomiting, diarrhea, abdominal or gastric pain, dyspnea and other symptoms. The major cause of death from a lethal dose is acute renal failure.

Human poison by unspecified routes. Moderately toxic experimentally by ingestion and intraperitoneal routes. Human systemic effects by ingestion: blood hemolysis with or without anemia, methemoglobinemiacarboxyhemoglobinemia and pulmonary changes. Mutation data reported. A skin, mucous membrane, and eye irritant. Damages the red blood cells of humans when ingested. A powerful oxidizer. It can explode on contact with flame or sparks (static discharge) and has caused many industrial explosions. May react explosively with agricultural materials (e.g., peat, powdered sulfur, sawdust, urotropine, thiuram), alkenes + potassium osmate, aluminum + rubber, ammonium salts, grease, leather, powdered metals, nonmetals, sulfides, cyanides, cyanoborane oligomer, nitrobenzene, organic matter, paint + polyethylene, phosphorus, sodium phosphinate. Violent reaction or ignition with aluminum, ammonium sulfate, Sb2S3, arsenic, arsenic trioxide, 1,3bis(trichloromethy1benzene) + heat, carbon, charcoal, MnOr, phosphorus, potassium cyanide, osmium + heat, paper, sulfuric acid, thiocyanates, triethylene glycol + wood, wood, zinc. Can also react violently with nitrobenzene, paper, metal sulfides, dibasic organic acids, organic matter. When heated to decomposition it emits toxic fumes of Cland Na2O. See also CHLORATES.
Sodium chlorate is used to manufacture dyes, explosives, in paper pulp processing and as a weed killer; used as a constituent of atratol and pramitol.

It is crystallised from hot water (0.5mL/g). It is a strong oxidising agent, and should be kept clear from organic matter.
A strong oxidizer. Potentially explosive. Reacts violently with combustibles, sulfuric acid; and reducing materials. Reacts with strong acids giving off carbon dioxide. Explosions may be caused by contact with ammonia salts; ammonium thiosulfate; antimony sulfide; arsenic, carbon, charcoal, organic matter; organic acids; thiocyanates, chemically active metals; oils, metal sulfides; nitrobenzene, powdered metals; sugar. Reacts with some organic contaminants forming shock-sensitive mixtures. Decomposes on heating above 300C or on burning, producing oxygen and toxic chlorine fumes. Attacks zinc, magnesium, and steel.
