反応性グループHydrocarbons, Aliphatic Unsaturated
Reactivity Profile1-DODECENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.
大気基準This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Dodecene is produced, as an intermediate or a final product, by process units covered under this subpart. /Dodecene/This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI).

非火災時の漏出対応Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]:
処分方法SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
漏出処分Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in covered containers as far as possible.
Preventive MeasuresSRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit 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.

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from a structure estimation method(2), indicates that 1-dodecene is expected to be immobile in soil. Volatilization of 1-dodecene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 1-Dodecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.0159 mm Hg(4). However, adsorption to soil is expected to attenuate volatilization. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in soil(5-7), but the rate of biodegradation in soil is unknown(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from an estimation method(2), indicates that 1-dodecene is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.3 hr and 120 hr, respectively, but these rates are expected to be attenuated by adsorption(SRC). The half-life for volatilization from a model pond, which takes into account adsorptive processes, is 17 months(8,SRC). According to a classification scheme(5), an estimated BCF of 310(SRC), from an estimated log Kow of 6.10(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in water(9-11), but the rate of biodegradation is unknown.ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-dodecene, which has a vapor pressure of 0.0159 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-dodecene 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 9.961 hr(SRC), calculated from its rate constant of 39X10-12 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3).

Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc for 1-dodecene can be estimated to be 5900(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-dodecene is expected to be immobile in soil(SRC).
