Decane

N-데칸 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid

물리적 성질

Clear, colorless liquid. Reported odor threshold concentrations were 11.3 mg/m3 by Laffort and Dravnieks (1973) and 620 ppbv by Nagata and Takeuchi (1990).

용도

Internal standard in the GC analysis of oxalic, malonic, and succinic acids in biological materials.

일반 설명

A colorless liquid. Flash point 115°F. Less dense than water and insoluble in water. Vapors heavier than air. In high concentrations its vapors may be narcotic. Used as a solvent and to make other chemicals.

공기와 물의 반응

Flammable. Insoluble in water.

반응 프로필

DECANE is incompatible with oxidizing agents.

건강위험

Contact with eyes may produce mild irritation. Contact with skin may cause defatting, redness, scaling, and hair loss. Ingestion may cause diarrhea, slight central nervous system depression, difficulty in breathing and fatigue. Inhalation of high concentrations may cause rapid breathing, fatigue, headache, dizziness, and other CNS effects.

화재위험

Special Hazards of Combustion Products: May produce toxic fumes, including carbon monoxide.

Safety Profile

Questionable carcinogen with experimental tumorigenic data. A simple asphyxiant. Narcotic in high concentrations, Flammable liquid when exposed to heat or flame. Can react with oxidizing materials. Moderately explosive in its vapor form. To fight fire, use foam, CO2, dry chemical. Emitted from modern buildtng materials (CENEAR 69,22,91). See also ARGON for discussion of asphyxiants.

Source

Major constituent in paraffin (quoted, Verschueren, 1983).
Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996).
California Phase II reformulated gasoline contained decane at a concentration of 1,120 mg/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 300 and 42,600 μg/km, respectively (Schauer et al., 2002).

환경귀착

Biological. Decane may biodegrade in two ways. The first is the formation of decyl hydroperoxide, which decomposes to 1-decanol, followed by oxidation to decanoic acid. The other pathway involves dehydrogenation to 1-decene, which may react with water giving 1-decanol (Dugan, 1972). Microorganisms can oxidize alkanes under aerobic conditions (Singer and Finnerty, 1984). The most common degradative pathway involves the oxidation of the terminal methyl group forming the corresponding alcohol (1-decanol). The alcohol may undergo a series of dehydrogenation steps, forming decanal, followed by oxidation forming decanoic acid. The fatty acid may then be metabolized by β-oxidation to form the mineralization products, carbon dioxide and water (Singer and Finnerty, 1984). Hou (1982) reported 1-decanol and 1,10-decanediol as degradation products by the microorganism Corynebacterium.
Photolytic. A photooxidation reaction rate constant of 1.16 x 10-11 cm3/molecule?sec was reported for the reaction of decane with OH in the atmosphere (Atkinson, 1990).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. Decane will not hydrolyze because it has no hydrolyzable functional group.

Purification Methods

It can be purified by shaking with conc H2SO4, washing with water, aqueous NaHCO3, and more water, then drying with MgSO4, refluxing with Na and distilling. Also purify through a column of silica gel or alumina. It has been purified by azeotropic distillation with 2-butoxyethanol, the alcohol being washed out of the distillate, using water, the decane is next dried and redistilled. It can be stored with NaH. Further purification can be achieved by preparative gas chromatography on a column packed with 30% SE-30 (General Electric methyl-silicone rubber) on 42/60 Chromosorb P at 150o and 40psig, using helium [Chu J Chem Phys 41 226 1964]. It is soluble in EtOH and Et2O. [Beilstein 1 IV 484.]
