바륨 브로마이트 C화학적 특성, 용도, 생산

개요

Barium bromate is used extensively to form other bromates, including the alkali metal bromates which are used extensively in Industry. HBrO3, a colorless liquid, is made by the addition of dilute sulfuric acid to barium bromate. It dissociates extensively in aqueous solution and is a strong acid.
The scientific literature contains a few studies of barium bromate chiefly due to interest in Industry for its use to prepare other bromate salts. This salt is available commercially, worldwide.

화학적 성질

Barium bromate is a white crystalline powder.

용도

Barium bromate [Ba(BrO3)2] is used as a corrosion inhibitor to prevent rust and as an oxidizing agent and chemical reagent.

제조 방법

Barium Bromate may be prepared by reaction of the hydroxide with sodium bromate:
Ba(OH)2＋ 2NaBrO3→Ba(BrO3)2＋ 2NaOH
Barium bromate is relatively insoluble, and has a value of 0.782 g/100 ml of water at 298 K,if recrystallized, it forms a monohydrate, Ba(BrO3)2·H2O, which occurs as white or colorless, prismatic crystals.
A new and general method of inducing a precipitation from homogeneous solution has been applied to the separation of barium and strontium. The precipitation of barium bromate, a water-soluble compound, is brought about by a gradual change in the composition of the solvent media. An organic compound, such as methanol or tetrahydrofuran, is allowed to diffuse into the original water solution, thus slowly converting the solution into a water organic mixture. Strontium bromate is about 40 times more soluble in water than barium bromate. The increased solubility plus the greater stability of the strontium MEDTA chelate tend to hold the strontium in solution. The chief advantage of this method over the separation of Sr from Ba by precipitation of barium chromate is in the preparation of barium compounds. Usually, barium must be separated from the chromate before proceeding. However, barium bromate can be easily converted to the oxide, eliminating this separation step.

일반 설명

A white crystalline solid or powder. Slightly soluble in water and denser than water. Very toxic by ingestion or inhalation. Fire hazard when in contact with organic materials and may explode when heated above 300°F. Used as a corrosion inhibitor and to manufacture other chemicals.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

BARIUM BROMATE is an oxidizing agent. May react violently with combustibles and reducing agents such as textiles, oil, fat, sugar, sawdust, ammonium salts, sulfur, carbon, phosphorus, metal powders and sulfides. A combination of finely divided aluminum with finely divided BARIUM BROMATE can explode by heat, percussion, or friction [Mellor 2:310 1946-47].

위험도

A poison. Moderate fire risk in contact with organic materials.

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

Very toxic. Fire hazard by chemical reaction with easily oxidued materials. Explodes at 300℃. Mmures with sulfur are unstable storage hazards; igniting immediately at 91 ℃ and after a 2-1 1 day delay period at room temperature. Incompatible with Al, As, C, Cu, metal sulfides, organic matter, P, and reducing materials. When heated to decomposition it emits toxic fumes of Br-. See also BARIUM COMPOUNDS (soluble) and BROMINE.

잠재적 노출

This material is used as an analytical reagent, oxidizer and corrosion inhibitor.

운송 방법

UN2719 Barium bromate, Hazard Class: 5.1; Labels: 5.1—Oxidizer, 6.1—Poisonous materials.

비 호환성

A strong oxidizer; keep away from reducing agents. Keep away from oxidizable materials; aluminum, arsenic, carbon, copper, metal sulfides; phosphorus, sulfur, organic, and combustible materials (such as wood, paper, oil, fuels), since violent reactions occur.
