브로민산나트륨 C화학적 특성, 용도, 생산

화학적 성질

White crystals or powder; odorless. Soluble in water; insoluble in alcohol.

화학적 성질

Sodium bromate is a colorless or white crystalline solid. Odorless.

용도

As a mixture with sodium bromide for dissolving gold from its ores.

정의

ChEBI: An inorganic sodium salt having bromate as the counterion.

일반 설명

A white crystalline solid. May explode under prolonged exposure to heat or fire. Used in chemical analysis.

공기와 물의 반응

Water soluble.

반응 프로필

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].

위험도

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

건강위험

Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.

화재위험

These substances will accelerate burning when involved in a fire. May explode from heat or contamination. Some may burn rapidly. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

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.

잠재적 노출

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

운송 방법

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.]

비 호환성

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.

폐기물 처리

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%).
