Description

Sodium bromate is an inorganic sodium salt with bromate as the counterion, which exists as a white crystalline solid or powder. It is odorless, soluble in water, and insoluble in alcohol. Sodium bromate may explode under prolonged exposure to heat or fire and is used in various applications due to its chemical properties.

Uses

1. Used in Gold Extraction:
Sodium bromate is used as a mixture with sodium bromide for dissolving gold from its ores, making it an essential component in the gold extraction process.
2. Used in Analytical Chemistry:
Sodium bromate acts as an analytical reagent in the field of chemistry, contributing to the accurate analysis and identification of various substances.
3. Used in Hair Treatment Formulations:
Sodium bromate is used in hair treatment formulations as a hair-permanent, providing a reliable and effective solution for hair styling and waving.
4. Used in Boiler Cleaning:
Sodium bromate serves as a cleaning agent for boilers, helping to maintain the efficiency and safety of these industrial systems.
5. Used in Flour and Dough Conditioning:
Although primarily used by potassium bromate, sodium bromate can also be used as a conditioner for flour and dough in the food industry, improving the texture and quality of the final product.
6. Used as an Oxidant in Organic Chemistry:
Sodium bromate is used as an oxidant to convert tetrahydropyranyl ethers to carbonyl compounds, playing a crucial role in organic synthesis.
7. Used in Oxidation of Sulfur and Vat Dyes:
Sodium bromate is utilized in the oxidation process of sulfur and vat dyes, contributing to the production of various industrial and commercial products.

Air & Water Reactions

Water soluble.

Reactivity Profile

Sodium bromate is an oxidizing agent. May react violently with combustibles and reducing agents. Reacts with textiles, oil, fat, grease, sugar, sawdust and ammonium salts, carbon, phosphorus, metal powders and sulfides with hazard of fire and explosion [Handling Chemicals Safely 1980 p. 831]. A mixture of finely divided aluminum with finely divided Sodium bromate explodes by heat, percussion, and friction [Mellor 2:310 1946-47].

Hazard

Oxidizing material, dangerous fire risk near organic materials. Toxic by ingestion.

Safety Profile

Poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. A powerful oxidizer. Violent reactions with Al, As, C, Cu, oil, F2, metal sulfides, organic matter, P, S. lxtures with grease are shock-sensitive explosives at 120’C. When heated to decomposition it emits toxic fumes of Na2O and Br-. See also BROMATES.

Potential Exposure

Used for research and development; as an analytical reagent; for separating gold from ores; making vat dyes; boiler cleaning.

Shipping

UN1494 Sodium bromate, Hazard Class: 5.1; Labels: 5.1-Oxidizer. UN1450 Bromates, inorganic, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, Technical Name Required.

Purification Methods

It is crystallised from hot water (1.1mL/g) to decrease contamination by NaBr, bromine and hypobromite. [Noszticzius et al. J Am Chem Soc 107 2314 1985.]

Incompatibilities

Dust may form explosive mixture with air. A strong oxidizer capable of increasing the intensity of an existing fire. Can react, possibly violently, with combustible, organic, or other oxidizable materials, alcohols, glycols, reducing agents, strong acids, finely divided metals, especially aluminum. Contamination with carbon, organic matter, and finely divided metal can cause sodium bromate become shock-sensitive. Decomposes at 381C. Sodium bromate may explode in heat of fire.

Waste Disposal

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations. See also Sigma-Aldridge data sheet (Sodium Bromate .99%).

Check Digit Verification of cas no

The CAS Registry Mumber 7789-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7789-38:
(6*7)+(5*7)+(4*8)+(3*9)+(2*3)+(1*8)=150
150 % 10 = 0
So 7789-38-0 is a valid CAS Registry Number.
