Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substances may be transported hot./GUIDE 128: FLAMMABLE LIQUIDS (NON-POLAR/WATER-IMMISCIBLE)/ Health: Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation.

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 68(SRC), determined from a structure estimation method(2), indicates that 3-methyl-1-butene is expected to have high mobility in soil(SRC). Volatilization of 3-methyl-1-butene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.54 atm-cu m/mole(SRC), determined using the vapor pressure of 903 mm Hg(4), and its water solublity value of 130 mg/l(5). The potential for volatilization of 3-methyl-1-butene from dry soil surfaces may exist(SRC) based upon its vapor pressure(4). 3-Methyl-1-butene's linear, relatively low molecular weight, hydrocarbon structure suggests that biodegradation in soil is expected to be an important fate process(6).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 68(SRC), determined from a structure estimation method(2), indicates that 3-methyl-1-butene is not 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 0.54 atm-cu m/mole(SRC), determined using its vapor pressure of 903 mm Hg(7), and its water solublity value of 130 mg/l(8). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 0.855 hr and 79.56 hr, respectively(SRC). 3-Methyl-1-butene's linear, relatively low molecular weight, hydrocarbon structure suggests that biodegradation in water is expected to be an important fate process(10). According to a classification scheme(5), an estimated BCF of 20(SRC), from an estimated log Kow of 2.6(6) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low.ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 3-methyl-1-butene, which has a vapor pressure of 903 mm Hg at 25 °C(2), is expected to exist solely as a gas in the ambient atmosphere. Gas-phase 3-methyl-1-butene 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 0.5 days(SRC), calculated from its estimated rate constant of 3.18X10-11 cu cm/molecule-sec at 25 °C(3). The rate constant for the gas-phase reaction of 3-methyl-1-butene with ozone has been measured as 9.50X10-18 cu cm/molecule-sec at 25 °C(4). This corresponds to an atmospheric half-life of about 1 hr at an atmospheric concentration of 7X10+11 ozone molecules per cu m(4). |

| Effluent Concentrations | 3-Methyl-1-butene is one of the alkenes formed during the combustion of fuel by various engines. The amount of 3-methyl-1-butene detected or its absence from the exhaust emissions is dependent upon the type of fuel used. 3-Methyl-1-butene was identified, not quantified, among the alkenes detected in the exhaust of an afterburning turbojet engine J85-GE-5B(1). The fuel used by the jet engines was kerosene JP5 (85.9% paraffins, 13.4% aromatics and 0.7% olefins). The exhaust emissions of two- (moped) and four-stroke (lawn mower) engines were tested for no-methane hydrocarbons using alkylate- and reformate-based fuels(2). 3-Methyl-1-butene constituted 0.09 weight percent of the emitted hydrocarbons even though it was not present in the alkylate-based fuel. It constituted 0.05 and 0.06 weight percent of reformate-based fuel and its exhaust, respectively. Amounts of C2-C6 hydrocarbons in the exhaust emissions of diesel-burning ferries was compared in Skagerak-Kattegatt-Oresund region of Sweden (3). The amount of 3-methyl-1-butene ranged from <0.03 to 0.05 mg/cu nm during both the crossing and the low-speed maneuvering of the ferries. 3-Methyl-1-butene was also detected in the stack emissions of waste incineration plants(4). |
|---|
| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc for 3-methyl-1-butene can be estimated to be about 68(SRC). According to a classification scheme(2), this estimated Koc value suggests that 3-methyl-1-butene is expected to have high mobility in soil. |

| Atmospheric Concentrations | SOURCE DOMINATED: 3-Methyl-1-butene was detected in an air samples from Atlanta collected between Aug 23-27, 1990 during the morning rush hour. The average concentration detected was 0.1583 +/- 0.0091 ppbC%(1). In air samples collected on Aug 27, 1990 from Atlanta's Hartsfield International Airport, an average concentration of 3-methyl-1-butene was monitored to be 0.090 +/- 0.022 ppbC%. 3-Methyl-1-butene was also detected in Tingstad Tunnel in Gotesborg, Sweden(2) in samples collected on Jun 6, 1991, Jan 15, Feb 10 and 19, 1992. The percent concentration ranged form 0.06 - 0.11% of the non-methane volatile hydrocarbons.URBAN/SUBURBAN: A small amount of 3-methyl-1-butene, in the range of 0-2 ppbV, was identified in the Los Angeles air during Septr 29-Nov 13, 1981(1). A mean concentration of 0.9 mg/cu m of 3-methyl-1-butene was measured in the ambient air samples collected during March 20, 1996 to April 16, 1997 in Porto Alegre, Brazil(2). 3-Methyl-1-butene was detected in the ambient atmosphere in city of Lancaster, Northwest England during May-July 1983 with a mean concentration of 38.3 ppbC(3).RURAL/REMOTE: 3-Methyl-1-butene was a minor component of C2-C6 hydrocarbons measured in rural Northwest England during May-July 1983(1). Mean concentration of 3-methyl-1-butene detected was <0.5 ppbC. |

| Artificial Pollution Sources | 3-Methyl-1-butene's production and use as an intermediate in the manufacture of high-octane fuel and petroleum resins may result in its release to the environment through various waste streams(1). It is emitted in vehicular exhaust from both gasoline and diesel engines(2,3). |
