화학적 성질

n-Heptane is a flammable liquid, present in crude oil and widely used in the auto- mobile industry. For example, as a solvent, as a gasoline knock testing standard, as automotive starter fl uid, and paraffi nic naphtha. n-Heptane causes adverse health effects in occupational workers, such as CNS depression, skin irritation, and pain. Other compounds such as n-octane (CH 3 (CH 2 ) 6 CH 3 ), n-nonane (CH 3 (CH 2 ) 7 CH 3 ), and n-decane (CH 3 (CH 2 ) 8 CH 3 ) have different industrial applications. Occupational workers exposed to these compounds also show adverse health effects. In principle, manage- ment of these aliphatic compounds requires proper handling and disposal to avoid health problems and to maintain chemical safety standards for safety to workers and the living environment.

Schauer et al. (1999) reported heptane in a diesel-powered medium-duty truck exhaust at an emission rate of 470 g/km.
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).
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of heptane was 28.9 mg/kg of pine burned. Emission rates of heptane were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained heptane at a concentration of 9,700 mg/kg.
Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 1.82 and 268 mg/km, respectively (Schauer et al., 2002).

환경귀착

Biological. Heptane may biodegrade in two ways. The first is the formation of heptyl hydroperoxide, which decomposes to 1-heptanol followed by oxidation to heptanoic acid. The other pathway involves dehydrogenation to 1-heptene, which may react with water forming 1- heptanol (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-heptanol). The alcohol may undergo a series of dehydrogenation steps forming heptanal followed by oxidation forming heptanoic acid. The acid may then be metabolized by β-oxidation to form the mineralization products, carbon dioxide and water (Singer and Finnerty, 1984). Hou (1982) reported hexanoic acid as a degradation product by the microorganism Pseudomonas aeruginosa.
Photolytic. The following rate constants were reported for the reaction of hexane and OH radicals in the atmosphere: 7.15 x 10-12 cm3/molecule?sec (Atkinson, 1990). Photooxidation reaction rate constants of 7.19 x 10-12 and 1.36 x 10-16 cm3/molecule?sec were reported for the reaction of heptane with OH and NO3, respectively (Sablji? and Güsten, 1990). Based on a photooxidation rate constant 7.15 x 10-12 cm3/molecule?sec for heptane and OH radicals, the estimated atmospheric lifetime is 19 h in summer sunlight (Altshuller, 1991).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. Heptane will not hydrolyze because it has no hydrolyzable functional group.
