푸란 C화학적 특성, 용도, 생산

화학적 성질

Furan is a cyclic dienic ether stabilized by benzene-like resonance. Because of its conjugated unsaturation and heterocyclic atom, furan will undergo many types of reactions. It is, therefore, of interest as a chemical intermediate for pharmaceuticals, insecticides and fine chemicals. The heterocyclic oxygen atom in a ring with conjugated unsaturation gives furan a combination of ether, aromatic and olefinic characteristics. This polyfunctionality permits it to undergo a variety of reactions. Compared to benzene, the furan ring has greater reactivity, and is more susceptible to cleavage, thus resembling the vinyl ethers. Like the vinyl ethers, the furan ring is cleaved by aqueous acids. This reaction is accompanied by resinification .

화학적 성질

Furan is a colorless liquid; turns brown on standing. Strong ethereal odor.

용도

Furan is a valuable chemical intermediate for pharmaceuticals, insecticides, and other organic compounds. The furan ring is cleaved by aqueous acid which can lead to polymer formation.

용도

Furan is a five-membered heterocyclic aromatic ring. Furan is used as a building block for the preparation of many heterocyclic compounds.

용도

In organic syntheses.

용도

Furan is used as an intermediate in organicsynthesis.

정의

A heterocyclic compound.

정의

A heterocyclic liquid organic compound. Its five-membered ring contains four carbon atoms and one oxygen atom. The structure is characteristic of some monosaccharide sugars (furanoses).

정의

furan: A colourless liquid compound,C4H4O; r.d. 0.94; m.p. –86°C;b.p. 31.4°C. It has a five-memberedring consisting of four CH2 groupsand one oxygen atom.

일반 설명

Furan is a stable, colourless chemical liquid. It is highly flammable and forms explosive mixtures with air. It is incompatible with many other chemical substances, for example, strong oxidising agents, acids, peroxides, and oxygen. Furan is produced commercially by decarbonylation of furfural. It is used mainly in the production of tetrahydrofuran, thiophene, and pyrrole. It also occurs naturally in certain woods and during the combustion of coal and is found in engine exhausts, wood smoke, and tobacco smoke.

공기와 물의 반응

Highly flammable. When uninhibited, Furan forms explosive peroxides on exposure to air. Insoluble in water.

반응 프로필

Furan is sensitive to heat and may turn brown upon standing. Furan may be light sensitive. When uninhibited, Furan forms explosive peroxides on exposure to air. Furan may react with oxidizers, acids, peroxides and oxygen. Furan resinifies on evaporation or when in contact with mineral acids, but Furan is stable in alkalis. .

위험도

Flammable, dangerous fire risk, flammable limits 2–24%, forms peroxides on exposure to air. Absorbed by skin. Possible carcinogen.

건강위험

The vapors are narcotic. Acute exposure to Furan by inhalation may involve both reversible and irreversible changes. Acute exposure by ingestion or skin absorption, as well as chronic exposure, are associated with high toxicity.

건강위험

Furan is a highly toxic compound. Inhalationof its vapors can cause acute pulmonaryedema and lung damage. The intraperitonealLD50 value in rodents is between 5 and7 mg/kg. The inhalation LC50 value in micefor a 1-hour exposure is 120 mg/m3.

화재위험

Very dangerous, upon exposure to heat or flame. Furan may form unstable peroxides on exposure to air. Contact with acids can initiate a violent, heat producing reaction. Avoid acids, oxidizing agents. Upon standing in air, Furan may form unstable peroxides.

Safety Profile

Confirmed carcinogen. Poison by inhalation and intraperitoneal routes. Moderately toxic by ingestion and skin contact. Experimental reproductive effects. A narcotic. Mutation data reported. The exposure concentration limit of 10 ppm together with its low boiling point requires that adequate ventilation be provided in areas where ths chemical is handled. Contact with liquid must be avoided since this chemical can be absorbed through the skin. Washing thoroughly with soap and water followed by prolonged rinsing should be done immedlatelp after accidental contact. A very dangerous fire hazard when exposed to heat or flame; can react with oxidzing materials. Unstabdized, it may form unstable peroxides on exposure to air and should always be tested before ddlation. Washing with an aqueous solution of ferrous sulfate slightly acidified with sodum bisulfate will remove these peroxides. Confirm by test. Contact with acids can initiate a violent exothermic reaction. Moderate explosion hazard when exposed to flame. Furan's low bohg point makes it easy to obtain explosive concentrations of the vapor in inadequately ventilated areas. To fight fire, use CO2, dr). chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also PEROXIDES.

잠재적 노출

Furan is used as a chemical intermedi ate in the production of herbicides and pharmaceuticals; for making tetrahydrofuran; in formation of lacquers; as a sol vent for resins in organic synthesis, especially for pyrrole, thiophene.

Carcinogenicity

Furan is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

운송 방법

UN2389 Furan, Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Shake it with aqueous 5% KOH, dry it with CaSO4 or Na2SO4, then distil it under nitrogen, from KOH or sodium, immediately before use. A trace of hydroquinone could be added as an inhibitor of oxidation. [Beilstein 17 H 27, 17 I 16, 17 II 34, 17/1 V 291.]

비 호환성

May form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong acids, amines, strong bases, reducing agents. Unless stabilized with an inhibitor, air exposure forms unstable peroxides.

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 govern ing storage, transportation, treatment, and waste disposal.
