바륨 클로라이드 C화학적 특성, 용도, 생산

개요

Barium dichloride is a white solid, odorless, hygroscopic chemical substance. Barium dichloride is used in the manufacture of pigments, in the manufacture of other barium salts and in fireworks to give a bright green color. It is one of the most common watersoluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. Barium chloride has wide application in the laboratory.

화학적 성질

Barium chloride,BaCI2, is a colorless toxic salt with a melting point of 963°C. It is soluble in water. Barium chloride is used in metal surface treatment and as a rat poison.

물리적 성질

Barium chloride has the formula, BaCl2 and is an ionic chemical compound. It is one of the most important water-soluble salts of barium-containing compounds. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. It is also hygroscopic. Barium chloride was the by-product of the discovery of radium by Madame Curie (1898).When refining radium, the final separation resulted in barium chloride and radium chloride. BaCl2 crystallizes in both the cubic “fluorite” and “lead chloride” crystal structures, both of which accommodate the preference of the large Ba2+ ion for coordination numbers greater than six.

용도

Barium chloride (BaCl2) is used in the manufacture of paint pigments and dyeing textiles and as an additive in oils. It is also used as a water softener.

용도

As a cheap, soluble salt of barium, barium chloride finds wide application in the laboratory. It is commonly used as a test for sulfate ion. In industry, barium chloride is mainly used chiefly in the synthesis of pigments and in the manufacture of rodenticides and pharmaceuticals. It is also used:
In the purification of brine solution in caustic chlorine plants.
In the manufacture of heat treatment salts.
For case hardening of steel.
In the manufacture of pigments.
In the manufacture of other barium salts such as barium hydroxide.
In fireworks to give a bright green color. However, its toxicity limits its applicability.
As a flux in the manufacture of magnesium metal.
For making color kinescope glass ceramics.
In wastewater treatment.
For the production of PVC stabilizers, oil lubricants, barium chromate and barium fluoride.
For stimulating the heart and other muscles for medicinal purposes.
For softening water.
For manufacturing of other barium salts used as pesticides, pigments, boiler detergent.
As a mordant in dyeing and printing textiles.
In the manufacture of caustic soda, polymers, and stabilizers.

제조 방법

Barium chloride can be prepared from barium hydroxide or barium carbonate, the latter being found naturally as the mineral “Witherite”. These basic salts react to give hydrated barium chloride. On an industrial scale, it is prepared via a two-step process

정의

barium chloride: A white compound,BaCl2. The anhydrous compoundhas two crystalline forms: anα form (monoclinic; r.d. 3.856),which transforms at 962°C to a βform (cubic; r.d. 3.917; m.p. 963°C;b.p. 1560°C). There is also a dihydrate,BaCl2.2H2O (cubic; r.d. 3.1),which loses water at 113°C. It is preparedby dissolving barium carbonate(witherite) in hydrochloric acid andcrystallizing out the dihydrate. Thecompound is used in the extractionof barium by electrolysis.

정의

ChEBI: The inorganic dichloride salt of barium.

일반 설명

Any of a variety of substances that contain barium. Most are whitish colored crystalline solids. They tend to be soluble in water and denser than water. They may be toxic by inhalation or possibly skin absorption. They are often used to make other chemicals.

공기와 물의 반응

Water soluble.

반응 프로필

BARIUM CHLORIDE may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.

위험도

Ingestion of 0.8 g may be fatal.

화재위험

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

공업 용도

Barium chloride (BaCl2·2H2O) is a colorless, white powder highly soluble in water (25% at 10 °C). It is quite a toxic reagent. Barium chloride is used during borite flotation as an activator. Barium chloride also has a depressing effect on fluorite and cassiterite.

Safety Profile

A poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Inhalation absorption of barium chloride equals 60-80%; oral absorption equals 10-30%. Experimental reproductive effects. Mutation data reported. See also BARIUM COMPOUNDS (soluble). When heated to decomposition it emits toxic fumes of Cl-.
