Sodium bromate, the inorganic compound with the chemical formula of NaBrO3, is the sodium salt of bromic acid. It is a strong oxidant.

Uses
Sodium bromate is mainly used in continuous or batch dyeing processes involving sulfur or vat dyes and as a hair-permagent, chemical agent, or gold solvent in gold mines when used with sodium bromide.

Production
Sodium bromate is produced by passing bromine into a solution of sodium carbonate.[1] It may also be produced by the electrolytic oxidation of sodium bromide. Alternatively, it can also be created by the oxidation of bromine with chlorine to sodium hydroxide at 80 °C.

Sodium bromate Chemical Properties,Uses,Production
Chemical Properties
White crystals or powder; odorless. Soluble in water; insoluble in alcohol.
Chemical Properties
Sodium bromate is a colorless or white crystalline solid. Odorless.
Uses
The bromates of chief industrial interest are those of sodium and potassium. Sodium bromate is used in mixtures with sodium bromide to extract gold from ore. It is also used as an analytical reagent, as a cleaning agent for boilers, and as a component in hair-waving formulations. Potassium bromate is used primarily as a conditioner for flour and dough; some of its nonfood uses include use as an oxidizing agent for analytic chemistry and as a brominating agent. The bromates of calcium and barium have limited use as oxidizers, maturing agents in flour, and analytic reagents.
Uses
As a mixture with sodium bromide for dissolving gold from its ores.

Oxidation of sulfides to sulfoxides with a catalytic amount of ceric ammonium nitrate reagent supported on silica gel has been achieved using stoichiometric sodium bromate as the primary oxidant. The heterogeneous CAN/NaBrO3 reagent enables the use of an organic solvent and simplifies the reaction work-up and product isolation.
The use of NaSO2CF3 and NaBrO3 enables a free-radical bromotrifluoromethylation of olefins via a radical process. Sodium bromate acts not only as a single-electron oxidant but also as a bromine source.
Sodium bromate is a powerful brominating agent for aromatic compounds that contain deactivating substituents. A bromination process, in which sodium bromate was utilized, was optimized on laboratory scale. Addition of a strong acid into a stirred aqueous solution, or slurry, of the substrate and bromate salt at 40-100°C, leads to the decomposition of the bromate ions and production of the active brominating species. Substrates such as nitrobenzene, benzoic acid, and benzaldehyde were brominated in high yields (85-98%) and specificity. The reaction is especially useful for the bromination of disubstituted benzenes, such as 4-nitrofluorobenzene or 4-fluorobenzoic acid. Several substrates, such as dinitrobenzenes or nitrobenzoic acids, did not undergo bromination at all. The main parameters of the reaction and some of its synthetic potential are discussed.
