Hydrocarbons, Aromatic

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DODECYLBENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

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.|Incineration: Liquids should be atomized into an incinerator and combustion may be improved by mixing with a more flammable solvent (acetone or benzene). Solids should be combined with paper or other flammable material. An alternate procedure is to dissolve the solid in a flammable solvent and spray the soln into the fire chamber.

Dodecylbenzene's production for use in detergents(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 7.4X10+5(SRC), determined from a log Kow of 8.26(2) and a regression-derived equation(3), indicates that dodecylbenzene is expected to be immobile in soil(SRC). Volatilization of dodecylbenzene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.13 atm-cu m/mole(SRC), using a fragment constant estimation method(4), but adsorption may severely attenuate this process. Dodecylbenzene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.1X10-5 mm Hg(5).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 7.4X10+5(SRC), determined from a log Kow of 8.26(2) and a regression-derived equation(3), indicates that dodecylbenzene 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 0.13 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4), but adsorption may severely attenuate this process(SRC). Volatilization half-lives for a model river and model lake are 4.5 hours and 6 days, respectively(SRC), using an estimation method(3) if adsorption is neglected. The estimated volatilization half-life from a model pond is 21 years if adsorption is considered(5). According to a classification scheme(6), a measured BCF value of 35(7) suggests that bioconcentration in aquatic organisms is moderate. River die-away tests have shown linear alkylbenzenes are readily biodegradable, with half-lives of 4.8 and 10.1 days for C-12 alkyl chain isomers in river water(8).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dodecylbenzene, which has a vapor pressure of 5.1X10-5 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase dodecylbenzene 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 19 hours(SRC) from its estimated rate constant of 2X10-11 cu cm/molecule-sec at 25 °C(3). Particulate-phase dodecylbenzene may be removed from the air by wet and dry deposition(SRC).

The rate constant for the vapor-phase reaction of dodecylbenzene with photochemically-produced hydroxyl radicals has been estimated as 2X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 19 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Dodecylbenzene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(2).

An estimated BCF of 38 was calculated for dodecylbenzene(SRC), using a log Kow of 8.26(1), and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests bioconcentration in aquatic organisms is moderate. The BCF value of bluegill sunfish exposed to dodecylbenzene in a flow-through aquarium was 35(4).

The Koc of dodecylbenzene is estimated as 7.4X10+5(SRC), using a log Kow of 8.26(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dodecylbenzene is expected to be immobile in soil.

The Henry's Law constant for dodecylbenzene is estimated as 0.13 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that dodecylbenzene is expected to volatilize rapidly from water surfaces(2), however adsorption may severely attenuate this process(SRC). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 9 hours if adsorption is neglected(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 4 days if adsorption is neglected(SRC). The estimated volatilization half-life from a model pond is 21 years if adsorption is considered(3). Dodecylbenzene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur, however adsorption may attenuate this process(SRC). Dodecylbenzene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.1X10-5 mm Hg at 25 °C(4).

Dodecylbenzene was detected in rivers in Tokyo, Japan at concns of 0.037-14.42 ng/l(1). Dodecylbenzene was identified, not quantified, in the Besos and Llobregat Rivers, Spain near heavily industrialized areas(2,3).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 21,273 workers (3,818 of these are female) are potentially exposed to dodecylbenzene in the US(1). Occupational exposure to dodecylbenzene may occur through inhalation and dermal contact with this compound at workplaces where dodecylbenzene is produced or used(SRC). The general population may be exposed to dodecylbenzene via dermal contact with this compound and other consumer products containing dodecylbenzene(SRC).

Liquid causes mild irritation of eyes and may cause allergenic responses on repeated contact with skin. Ingestion causes nausea. (USCG, 1999)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

Fresh air, rest.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
