개요

세고리 방향족 탄화수소다.벤젠 고리 3개가 일렬로 붙어서 14개의 π전자를 갖게 되어 분자가 방향족성을 띈다.

용도

나프탈렌과는 달리 더 길어진 π시스템의 영향으로 자외선을 받으면 보라색 형광을 내기 시작한다. 콜타르에서 발견되며, 유기분자 주제에 반도체 성질을 띄기 때문에 염료나 유기광전자소자의 반도체 재료의 유도체로 사용된다.

개요

Anthracene is one of a group of chemicals called polycyclic aromatic hydrocarbons (PAHs). PAHs are often found together in groups of two ormore. They can exist inmore than 100 different combinations, but the most common are treated as a group of 15. PAHs are found naturally in the environment but they can also be made synthetically. Anthracene can vary in appearance from a colorless to pale yellow crystal-like solid. PAHs are created when products like coal, oil, gas, and garbage are burned but the burning process is not complete. Very little information is available on the individual chemicals within the PAH group; the majority of the information is for the entire PAH group. Anthracene is a solid white to yellow crystal, has a weak aromatic odor, and sinks in water. Its characteristics are boiling point, 3421°C; melting point, 2181°C; molecular weight, 178.22; density/specific gravity, 1.25 at 27 and 41°C; octanol–water coefficient, 4.45. It is soluble in absolute alcohol and organic solvents. Maximum absorption occurs at 218 nm.

화학적 성질

Anthracene is colorless, to pale yellow crystalline solid with a bluish fluorescence. PAHs are compounds containing multiple benzene rings and are also called polynuclear aromatic hydrocarbons.

물리적 성질

White to yellow crystalline flakes or crystals with a bluish or violet fluorescence and a weak aromatic odor. Impurities (naphthacene, tetracene) impart a yellowish color with green fluorescence.

용도

Anthracene is an aromatic hydrocarbonwith three fused rings, and is obtained by the distillationof crude oils. The main useis in the manufacture of dyes.It is an important source of dyestuffs.

정의

(C₁₄H₁₀) A white crystalline solid used extensively in the manufacture of dyes. Anthracene is found in the heavy- and green-oil fractions of crude oil and is obtained by fractional crystallization. Its structure is benzene-like, having three six-membered rings fused toanion gether. The reactions are characteristic of AROMATIC COMPOUNDS.

생산 방법

Anthracene is obtained from coal tar in the fraction distilling between 300° and 400 °C. This fraction contains 5–10% anthracene, from which, by fractional crystallization followed by crystallization from solvents, such as oleic acid, and washing with such solvents as pyridine, relatively pure anthracene is obtained. It may be detected by the formation of a blue-violet coloration on fusion with mellitic acid. Anthracene derivatives, especially anthraquinone, are important in dye chemistry.

화학 반응

Anthracene reacts: (1) With oxidizing agents, e.g., sodium dichromate plus sulfuric acid, to form anthraquinone, C6H4(CO)2C6H. (2) With chlorine in water or in dilute acetic acid below 250 °C to form anthraquinol and anthraquinone, at higher temperatures 9,10-dichloroanthracene. The reaction varies with the temperature and with the solvent used. The reaction has been studied using, as solvent, benzene, chloroform, alcohol, carbon disulfide, ether, glacial acetic acid, and also without solvent by heating. Bromine reacts similarly to chlorine. (3) With concentrated sulfuric acid to form various anthracene sulfonic acids. (4) With nitric acid, to form nitroanthracenes and anthraquinone. (5) With picric acid (1)HO·C6H2(NO2)3(2,4,6) to form red crystalline anthracene picrate, melting point 138 °C.

일반 설명

White to yellow solid with a weak aromatic odor. Sinks in water.

공기와 물의 반응

Flammable. Insoluble in water.

반응 프로필

Anthracene will spontaneously burst into flame on contact with chromic acid, and other strong oxidants.

위험도

A questionable carcinogen.

건강위험

Carcinogenicity of anthracene is not known.Its toxicity is very low. An intraperitonealLD50 in mice is recorded at 430 mg/kg(NIOSH 1986).

화재위험

Anthracene is combustible.

Safety Profile

Moderately toxic by intraperitoneal route. A skin irritant and allergen. Questionable carcinogen with experimental neoplas tigenic and tumorigenic data. Mutation data reported. Combustible when exposed to heat, flame, or oxidizing materials. Moderately explosive when exposed to flame, Ca(OCl)z, chromic acid. To fight fire, use water, foam, CO2, water spray or mist, dry chemical. Explodes on contact with fluorine.

잠재적 노출

It is used as an intermediate in dye stuffs (alizarin), insecticides, and wood preservatives; making synthetic fibers, anthraquinone, and other chemicals. May be present in coke oven emissions, diesel fuel, and coal tar pitch volitiles.

Carcinogenicity

Anthracene was negative in mouse-skin-painting studies, and it is classified as a noncarcinogen by the IARC based on inadequate evidence. The methyl, anthryl, dimethyl, diprophyl, dinaphthyl, and tetramethyl derivatives of anthracene were noncarcinogenic except for 9,10-dimethyl anthracene, which may have contained impurities when tested.

운송 방법

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

비 호환성

Finely dispersed powder may form explosive mixture in air. Contact with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, chromic acid/or calcium hypochlorite.

폐기물 처리

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incineration.
