메틸시클로펜탄 C화학적 특성, 용도, 생산
화학적 성질
Methylcyclopentane is a colorless, flammable liquid with a sweet gasoline-like odor. An odor threshold concentration of 1.7 ppmv was reported by Nagata and Takeuchi (1990). Soluble in ether, miscible with alcohol and benzene, insoluble in water.용도
Methylcyclopentane can undergo ring opening or ring enlargement to yield various hydrocarbons including branched and unbranched hexanes, cyclohexane and benzene.정의
ChEBI: Methylcyclopentane is a cycloalkane that is cyclopentane substituted by a single methyl group. It has a role as a human metabolite and a plant metabolite. It is a cycloalkane and a volatile organic compound. It derives from a hydride of a cyclopentane.제조 방법
Methylcyclopentane mainly exists in industrial hexane, accounting for about 5%. However, because its boiling point is close to that of n-hexane (68.74°C), it is difficult to completely separate it by general rectification methods. Therefore, methylcyclopentane with a purity of more than 99% can be obtained by azeotropic distillation with methanol.일반 설명
Methylcyclopentane appears as a colorless liquid. Insoluble in water and less dense than water. Flash point near 20 °F. Very dangerous fire risk. Vapors may be narcotic and irritating. Used to make other chemicals.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
Methylcyclopentane can react vigorously with oxidizers. (NTP, 1992).위험도
Flammable, dangerous fire and explosionrisk. May be irritant and narcotic.건강위험
Inhalation causes dizziness, nausea, and vomiting; concentrated vapor may cause unconsciousness and collapse. Liquid causes irritation of eyes and mild irritation of skin if allowed to remain. Ingestion causes irritation of stomach. Aspiration causes severe lung irritation, rapidly developing pulmonary edema, and central nervous system excitement followed by depression.화재위험
Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.Safety Profile
Mildly toxic by inhalation. Probably irritating and narcotic in high concentration. Very dangerous fire hazard when exposed to heat, flame, or oxidizers. Can react vigorously with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.잠재적 노출
This material is used as a solvent; as a fuel; and in chemical synthesis.환경귀착
Photolytic. A photooxidation rate constant of 7.0 x 10-12 cm3/molecule?sec was reported for the reaction of methylcyclopentane and OH radicals in the atmosphere (Atkinson, 1990).Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. Methylcyclopentane will not hydrolyze because it does not contain a hydrolyzable functional group.
At elevated temperatures, rupture of the ring occurs and 1-propene is produced in a 40% yield. Other products include hydrogen and cyclic mono- and diolefins (Rice and Murphy, 1942).
운송 방법
UN2298 Methyl cyclo pentane, Hazard Class: 3; Labels: 3-Flammable liquidPurification Methods
Purification procedures include passage through columns of silica gel (prepared by heating in nitrogen to 350o prior to use) and activated basic alumina, distillation from sodium-potassium alloy, and azeotropic distillation with MeOH, followed by washing out the methanol with water, drying and distilling. It can be stored with CaH2 or sodium. [Vogel J Chem Soc 1331 1938, Beilstein 5 III 55, 5 IV 84.]비 호환성
Incompatible with 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.폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.메틸시클로펜탄 준비 용품 및 원자재
