개요

인체 내에서 아연은 세포를 구성하고 생리적인 기능을 다루는 대표적인 무기물 중 하나이다. 임신한 여성에게 아연이 부족하게 되면 기형아나 저체중아를 낳을 수 있다. 아연이 부족할 경우 성장발육에 문제가 있게 되며, 아연을 과잉섭취하게 되어도 미네랄 불균형이 생긴다. 식물체 내에서의 아연은 식물체 내에서 발생하는 유해한 활성산소를 제거하는 효소 구성 성분으로, 망가니즈나 마그네슘 등과 같이 효소를 활성화시키는 역할을 한다.

개요

1,3-Butadiene is a simple conjugated diene. It is a colourless gas with a mild aromatic or gasoline-like odour and incompatible with phenol, chlorine dioxide, copper, and crotonaldehyde. The gas is heavier than air and may travel along the ground; distant ignition is possible. It is an important industrial chemical used as a monomer in the production of synthetic rubber. Most butadiene is polymerised to produce synthetic rubber. While polybutadiene itself is a very soft, almost liquid, material, polymers prepared from mixtures of butadiene with styrene or acrylonitrile, such as ABS, are both tough and elastic. Styrene–butadiene rubber is the material most commonly used for the production of automobile tyres. Smaller amounts of butadiene are used to make nylon via the intermediate adiponitrile, other synthetic rubber materials such as chloroprene, and the solvent sulpholane. Butadiene is used in the industrial production of cyclododecatriene via a trimerisation reaction.

1,3-Butadiene structure

물리적 성질

Colorless gas with a mild, aromatic or gasoline-like odor. Experimentally determined detection and recognition odor threshold concentrations were 1.0 mg/m3 (0.45 ppmv) and 2.4 mg/m3 (1.1 ppmv), respectively (Hellman and Small, 1974).

용도

1,3-Butadiene is a petroleum product obtainedby catalytic cracking of naphtha orlight oil or by dehydrogenation of buteneor butane. It is used to produce butadiene–styrene elastomer (for tires), syntheticrubber, thermoplastic elastomers, foodwrapping materials, and in the manufactureof adiponitrile. It is also used forthe synthesis of organics by Diels–Aldercondensation.

용도

Synthetic elastomers (styrene-butadiene, polybutadiene, neoprene, nitriles), ABS resins, chemical intermediate.
1,3-Butadiene can undergo a four-component coupling reaction with aryl Grignard reagents, and alkyl fluorides in the presence of nickel catalyst to form 1,6-octadiene carbon compound substituted with alkyl and aryl groups at the 3- and 8-positions.
1,3-Butadiene is a useful diene for Diels Alder reaction.
It may be used in the synthesis of the following:

정의

ChEBI: A butadiene with unsaturation at positions 1 and 3.

생산 방법

Except for a small amount of butadiene produced by the oxydehydrogenation of n-butane, most of butadiene is produced commercially as a by-product of ethylene production during the steam cracking of hydrocarbon streams. It is separated and purificated from other components by extractive distillation, using acetonitrile and dimethylformamide as solvents.

일반 설명

Butadiene, inhibited is a colorless gas with an aromatic odor. 1,3-BUTADIENE is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. 1,3-BUTADIENE is easily ignited. Its vapors are heavier than air and a flame can flash back to the source of leak very easily. 1,3-BUTADIENE can asphyxiate by the displacement of air. 1,3-BUTADIENE must be shipped inhibited as butadiene is liable to polymerization. If polymerization occurs in the container, 1,3-BUTADIENE may violently rupture. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. 1,3-BUTADIENE is used to make synthetic rubber and plastics, and to make other chemicals.

공기와 물의 반응

Highly flammable. In contact with air, butadiene may form violently explosive peroxides, which can be exploded by mild heat or shock. Solid butadiene absorbs enough oxygen at sub atmospheric pressures to make 1,3-BUTADIENE explode violently when heated just above its melting point [Ind. Eng. Chem. 51:733 1959].

반응 프로필

A colorless gas, 1,3-BUTADIENE can react with oxidizing reagents. Upon long exposure to air 1,3-BUTADIENE forms explosive peroxides. They are sensitive to heat or shock; sudden polymerization may occur [Scott, D. A., Chem. Eng. News, 1940, 18, p.404]. Butadiene polyperoxides are insoluble in liquefied butadiene (m. p. -113° C, b. p. -2.6° C) and progressively separate leading to local concentration build up. Self-heating from a spontaneous decomposition will lead to explosion [Hendry, D. G. et al., Ind. Eng. Chem., 1968, 7, p. 136, 1145]. Explodes on contact with aluminum tetrahydroborate, potentially explosive reaction with chlorine dioxide (peroxide) and crotonaldehyde (above 180° C). Reaction with sodium nitrite forms a spontaneously flammable product [Sax, 9th ed., 1996, p. 539].

위험도

A confirmed carcinogen. Irritant in high concentration. Highly flammable gas or liquid, explosive limits in air 2–11%. May form explosive peroxides on exposure to air. Must be kept inhibited during storage and shipment. Inhibitors often used are di-n-butylamine or phenyl-β-naphthylamine. Storage is usually under pressure or in insulated tanks <35F (<1.67C).

건강위험

The toxicity of 1,3-butadiene has been foundto be very low in humans and animals. It isan asphyxiant. In humans, low toxic effectsmay be observed at exposure to 2000 ppmfor 7 hours. The symptoms may be hallucinations,distorted perception, and irritation ofeyes, nose, and throat. Higher concentrationsmay result in drowsiness, lightheadedness,and narcosis. High dosages of 1,3-butadienewas toxic to animals by inhalation and skincontact. General anesthetic effects and respiratorydepression were noted. Concentrationsof 25–30% may be lethal to rats and rabbits.Contact with the liquefied gas can cause burnand frostbite.
Exposure to 1,3-butadiene caused cancersin the stomach, lungs, and blood in ratsand mice. It is suspected to be a humancarcinogen. It is a mutagen and a teratogen.

화재위험

Behavior in Fire: Vapors heavier than air and may travel a considerable distance to a source of ignition and flashback. Containers may explode in a fire due to polymerization.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. An experimental teratogen. Mutation data reported. Inhalation of high concentrations can cause unconsciousness and death. Human systemic effects by inhalation: cough, hallucinations, dstorted perceptions, changes in the visual field and other

Carcinogenicity

1,3-Butadiene is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans, including epidemiological and mechanistic studies. 1,3-Butadiene was first listed in the Fifth Annual Report on Carcinogens in 1989 as reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. The listing was revised to known to be a human carcinogen in the Ninth Report on Carcinogens in 2000.

Source

Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of 1,3-butadiene was 177 mg/kg of pine burned. Emission rates of 1,3-butadiene were not measured during the combustion of oak and eucalyptus.

환경귀착

Surface Water. The estimated volatilization half-life of 1,3-butadiene in a model river 1 m deep, flowing 1 m/sec and a wind speed of 3 m/sec is 3.8 h (Lyman et al., 1982).
Photolytic. The following rate constants were reported for the reaction of 1,3-butadiene and OH radicals in the atmosphere: 6.9 x 10-11 cm3/molecule·sec (Atkinson et al., 1979) and 6.7 x 10-11 cm3/molecule·sec (Sablji? and Güsten, 1990). Atkinson and Carter (1984) reported a rate constant of 6.7–8.4 x 10-11 cm3/molecule·sec for the reaction of 1,3-butadiene and ozone in the atmosphere. Photooxidation reaction rate constants of 2.13 x 10-13 and 7.50 x 10-18 cm3/molecule·sec were reported for the reaction of 1,3-butadiene and NO3 (Benter and Schindler, 1988; Sablji? and Güsten, 1990). The half-life in air for the reaction of 1,3-butadiene and NO3 radicals is 15 h (Atkinson et al., 1984a).
Chemical/Physical. Will polymerize in the presence of oxygen if no inhibitor is present (Hawley, 1981).

저장

1,3-Butadiene is stored in a cool and wellventilatedlocation separated from combustibleand oxidizing substances. Smallamounts of stabilizers, such as o-dihydroxybenzene,p-tert-butylcatechol, or aliphaticmercaptans, are added to prevent its polymerizationor peroxides formation. The cylindersare stored vertically and protected againstphysical damage.
