| Reaktive Gruppe | Hydrocarbons, Aliphatic Saturated |
| Reactivity Profile | Saturated aliphatic hydrocarbons, such as N-HEPTADECANE, 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. |

Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value of 2.5X10+5(2), indicates that heptadecane is expected to be immobile in soil(SRC). Volatilization of heptadecane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.1X10-2 atm-cu m/mole(3), derived from its vapor pressure, 2.28X10-4 mm Hg(4), and water solubility, 2.3X10-3 mg/L(2). However, adsorption to soil is expected to attenuate volatilization(SRC). Heptadecane is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Heptadecane achieved 7 to 29% biodegradation after 28 days in sediment and marine-water inoculums(5), indicating that biodegradation is an important environmental fate process under certain conditions in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), a Koc value of 2.5X10+5(2), indicates that heptadecane is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.1X10-2 atm-cu m/mole(4) derived from its vapor pressure, 2.28X10-4 mm Hg(5), and water solubility, 2.3X10-3 mg/L(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.6 hours and 6.2 days, respectively(SRC). However, adsorption to suspended solids and sediment is expected to attenuate volatilization(SRC). The estimated volatilization half-life from a model pond is greater than 2 years if adsorption is considered(6). According to a classification scheme(7), an estimated BCF of 500(SRC), from its estimated log Kow of 8.69(4) and a regression-derived equation(4), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Heptadecane has a calculated half-life of 2.3 days in unacclimated pond-water(8), indicating that biodegradation is an important environmental fate process under certain conditions in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), heptadecane, which has a vapor pressure of 2.28X10-4 mm Hg at 25 °C(2), is expected to exist almost entirely as a vapor in the ambient atmosphere. Vapor-phase heptadecane is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 18 hours(SRC), calculated from its rate constant of 21X10-21 cu cm/molecule-sec at 25 °C(SRC)that was derived using a structure estimation method(3). Heptadecane does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |
