브롬화 시안 C화학적 특성, 용도, 생산

화학적 성질

white crystalline solid

화학적 성질

Cyanogen bromide is a colorless or white, volatile, crystalline solid with a penetrating odor.

용도

Reaction with C60Ph5Cl produces a novel phenylated isoquinolino[3′,4′:1,2][60]fullerene.1

용도

Reagent for the synthesis of cyanamides.

용도

Cyanogen bromide is used in organic synthesis and as a reagent in bioanalysis.

일반 설명

Cyanogen bromide is a colorless to white crystalline solid with a penetrating odor. Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a flammable and poisonous gas. Contamination with many materials can cause rapid decomposition of the material. Cyanogen bromide is toxic by inhalation of its vapors or by the hydrogen cyanide from decomposition or by ingestion. Toxic oxides of nitrogen are produced in fire involving Cyanogen bromide. Cyanogen bromide is used in gold extraction, to make other chemicals, and as a fumigant.

공기와 물의 반응

Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a poison gas.

반응 프로필

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control. [EPA, 1998]. Benzene and cyanogen halides yield HCl as a byproduct (Hagedorn, F. H. Gelbke, and Federal Republic of Germany. 2002. Nitriles. In Ullman Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA.).

건강위험

Super toxic; probable oral lethal dose in humans is less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lb.) person. Vapors are highly irritant and very poisonous. Individuals with chronic diseases of the kidneys, respiratory tract, skin, or thyroid are at greater risk of developing toxic cyanide effects.

건강위험

Exposure to cyanogen bromide is dangerous. The chemical substance is poisonous and causes fatal injury if swallowed, inhaled, or absorbed through the skin. It is corrosive and the vapors cause severe irritation to the eyes and respiratory tract, and cause burns to any area of contact. On contact with acids, cyanogen bromide liberates poisonous gas, affecting the blood, cardiovascular system, CNS, and thyroid.

건강위험

The acute toxicity of cyanogen bromide is high. Toxic effects are similar to but not as severe as those of hydrogen cyanide. Toxic symptoms may include cyanosis, nausea, dizziness, headache, lung irritation, chest pain, and pulmonary edema, which may be fatal.
Cyanogen bromide may cause chronic pulmonary edema.

건강위험

Cyanogen bromide is a highly toxic substance. Its toxic effects are similar to those of HCN. However, it is not as toxic as HCN. Because it volatilizes readily at ambient temperature, inhalation is the major toxic route. The toxic symptoms in humans may be nausea, headache, and chronic pulmonary edema. Exposure to 100 ppm for 10 minutes can be fatal to humans.
LC50 inhalation (mice): 500 mg/m3/10 min
Cyanogen bromide is an irritant.

화재위험

Cyanogen bromide is noncombustible. Impure material decomposes rapidly and can be explosive.

화재위험

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Vapors are highly irritating. When material is heated to decomposition, Cyanogen bromide emits very toxic fumes of cyanide and bromide. Avoid water, acids. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control.

인화성 및 폭발성

Cyanogen bromide is noncombustible. Impure material decomposes rapidly and can be explosive.

Safety Profile

A human and experimental poison by inhalation. Corrosive. When heated to decomposition it emits very toxic fumes of CNand Br-. Possibly unstable. See also other cyanogen entries; CYANIDE; and BROMIDES.

잠재적 노출

Used as an activating reagent for insoluble supports for affinity absorption. In danger are those manufacturing this compound or using it in organic synthesis or as a fumigant; in textile treatment; in gold cyaniding. It may have been used as a military poison gas.

저장

work with BrCN should be conducted in a fume hood to prevent exposure by inhalation, and splash goggles and impermeable gloves should be worn at all times to prevent eye and skin contact. Containers of cyanogen bromide should be kept tightly sealed and stored under nitrogen in a secondary container in a refrigerator.

운송 방법

UN1889 Cyanogen bromide, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 8-Corrosive material. A DOT regulated marine pollutant.

Purification Methods

All operations with this substance should be performed in a very efficient fume cupboard-it is very POISONOUS and should be handled in small amounts. Fresh commercial material is satisfactory for nearly all purposes and does not need to be purified. It is a white crystalline solid with a strong cyanide odour. If it is reddish in colour and partly liquid or paste-like, then it is too far gone to be purified, and fresh material should be sought. It can be purified by distillation using small amounts at a time, and using a short wide-bore condenser because it readily solidifies to a crystalline white solid which may clog the condenser. An appropriate gas mask should be used when transferring the molten solid from one container to another, and the operation should be done in an efficient fume cupboard. The melting point (m 49-51o) should be measured in a sealed tube. [Hartman & Dreger Org Synth Coll Vol II 150 1948.]

비 호환성

May be unstable unless dry and pure; impure cyanogen bromide decomposes rapidly and tends to explode. Cyanogen bromide decomposes violently on heat- ing or on contact with water, acids, or acid vapors; produc- ing highly toxic and flammable hydrogen cyanide and corrosive hydrogen bromide. Avoid physical damage, con- tact with acids or water, and store away from a location where water may be needed for fire control . Violent reaction with ammonia, amines.

폐기물 처리

May be added to strong alka- line solution of calcium hypochlorite, let stand for 24 hours and flush to sewer. May also be dissolved in flammable solvent and sprayed into an incinerator equipped with after- burner and scrubber.
