도데칸 C화학적 특성, 용도, 생산
화학적 성질
Dodecane, C12H26, is a flammable, colorless liquid with specific gravity 0.749. It occurs in the paraffin fraction of petroleum. Dodecane is released to the environment by wastewater and spills from laboratory and general use of paraffins, petroleum oils, and tars.물리적 성질
Clear, colorless liquid with a mild aliphatic hydrocarbon odor. An odor threshold concentration of 620 ppbv was reported by Nagata and Takeuchi (1990).용도
Dodecane is a component of gasoline and is used as solvent, in organic synthesis, in jet fuel research, as a distillation chaser, and in the rubber and paper processing industries.정의
ChEBI: A straight-chain alkane with 12 carbon atoms. It has been form the essential oils of various plants including Zingiber officinale (ginger).생산 방법
Dodecane is isolated from the kerosene and gas oil fractions of crude oil by selective adsorption and subsequent desorption to yield mixtures of paraffins that can be separated by fractional distillation.일반 설명
Clear colorless liquid.공기와 물의 반응
Flammable. Insoluble in water.반응 프로필
Saturated aliphatic hydrocarbons, such as Dodecane, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water.화재위험
Dodecane is combustible.Carcinogenicity
Dodecane has been shown to be a promoter of skin carcinogenesis for benzo[a]pyrene and ultraviolet radiation.환경귀착
Biological. Dodecane may biodegrade in two ways. The first is the formation of dodecyl hydroperoxide which decomposes to 1-dodecanol. The alcohol is oxidized forming dodecanoic acid. The other pathway involves dehydrogenation to 1-dodecene, which may react with water, giving 1-dodecanol (Dugan, 1972).Estimated half-lives of dodecane (0.3 μg/L) from an experimental marine mesocosm during the spring (8–16 °C), summer (20–22 °C), and winter (3–7 °C) were 1.1, 0.7, and 3.6 d, respectively (Wakeham et al., 1983).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water. Dodecane will not hydrolyze because it has no hydrolyzable functional group.
Purification Methods
Pass it through a column of Linde type 13X molecular sieves. Store it in contact with, and distil it from sodium. Pass through a column of activated silica gel. It has been crystallised from diethyl ether at -60o. Unsaturated dry material which remained after passage through silica gel has been removed by catalytic hydrogenation (Pt2O) at 45lb/in2 (3.06 atmospheres), followed by fractional distillation under reduced pressure [Zook & Goldey J Am Chem Soc 75 3975 1953]. It has also purified by partial crystallisation from the melt. [Beilstein 1 IV 498.]도데칸 준비 용품 및 원자재
