Hydrocarbons, Aromatic

Highly Flammable

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as PROPYL BENZENE, 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.

The major hazards encountered in the use and handling of n-propylbenzene stem from its toxicologic properties and flammability. Toxic by all routes (ie, inhalation, ingestion, dermal contact), exposure to this colorless liquid may occur from its use in textile dyeing and printing, as a solvent for cellulose acetate, and in the manufacture of methylstyrene. Effects from exposure may include burns to the skin and eyes, nausea, headache, dizziness, central nervous system depression, and unconsciousness. In activities and situations where over-exposure may occur, wear a positive pressure self-contained breathing apparatus and protective clothing. If contact should occur, immediately irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes, and wash exposed skin thoroughly with soap and water. Contaminated clothing should be removed and left at the site. This substance is flammable and may be ignited by heat, sparks, or flames. Its heavier-than-air vapor may travel to a source of ignition and flash back, or accumulate to explosive concentrations in enclosed spaces, such as sewers. Also, containers of n-propylbenzene may explode in the heat of a fire. For fires involving this substance, extinguish with dry chemical, CO2, water spray, fog, or alcohol-resistant foam. Isolate for 1/2 mile in all directions if tank, rail car or tank truck is involved in the fire. For small spills of n-propylbenzene, take up with sand or other noncombustible absorbent, and place into container for later disposal. Dike far ahead of large spills to contain for later disposal.

n-Propylbenzene has been qualitatively detected in various wastewaters from the following industries: petroleum refining, textile mills, auto and other laundries, plastics mfg, and publicly owned treatment works(1). Leachate from 4 hazardous waste landfills in Germany contained n-propylbenzene levels of 10-700 ug/l(3). An n-propylbenzene concn of 69 mg/cu m was detected in gas emissions from a landfill in Great Britain(4). An aqueous effluent from a US petroleum refinery had a n-propylbenzene concn of 13 ng/g(5). n-Propylbenzene is a component of leachate from a landfill in Germany, being detected up to a distance of 56 m(5). Maximum concns of n-propylbenzene in the off-gas at aerated grit chambers in two Ontario, Canada municipal wastewater treatment plants were 205 and 203 ug/l(6).|Based upon dynamometer tests, the avg n-propylbenzene emission rate from gasoline-powered engines is 1.2 mg/km(1). Emission rates for n-propylbenzene from motor vehicles was calculated to be 34 mg/l of fuel consumed based on measurements made inside and outside a Los Angeles roadway tunnel(2). It is also a component of exhaust emissions from four-stroke lawn mower engines: n-propylbenzene comprised 0.57% of total organic emissions from baseline gasoline and 0.55% of total organic emissions in reformulated gasoline(3). Four stroke outboard motors are also a source of n-propylbenzene into surface waters(4).|n-Propylbenzene has also been detected as a possible volatile (C3-benzene) from furniture coatings for wood-based materials(1) and as a volatile emission from building materials (concn): linoleum tile (2.3 ug-sq m/hr); black rubber molding (0.96 ug-sq m/hr); vinyl edge molding (0.34 ug-sq m/hr); large diameter telephone cable (0.65 ug-sq m/hr); small diameter telephone cable (0.79 ug-sq m/hr); polystyrene foam insulation (0.70 ug-sq m/hr); cove adhesive (110 ug-sq m/hr); latex caulk (2.7 ug-sq m/hr); carpet (0.49 ug-sq m/hr)(2).

n-Propylbenzene was not detected (detection limit 5-23 ppb) in sediments collected from the Duwamish River Delta (Puget Sound, WA)(1).

SOURCE DOMINATED: n-Propylbenzene was detected in tunnel air at 0.037 g/kg (traffic) and 0.052 (congested) from the Craeybeckx highway tunnel in Antwerp Belgium(1).|URBAN/SUBURBAN: An evaluated database of US air monitoring data for the years 1970-1987 contains the following data for n-propylbenzene (concn is reported as daily median conc): suburban sites-213 samples, 0.123 ppb; urban sites-520 samples, 0.167 ppb(1). Air samples collected in Tulsa, OK in Jul 1978 contained n-propylbenzene levels of 0-0.9 ppb(2); samples from Rio Blanco County, CO (Jul 1978) had levels of 0.5-1.6 ppb(2). Ambient air samples collected in Long Beach, Burbank, Azuza, Los Angeles and Inglewood, CA (date no reported) contained n-propylbenzene levels of 0.001-0.011 ppm(3). The avg concn in the ambient air of Sydney, Australia between Sep 1979 and June 1980 (140 samples) was 0.4 ppb(4). The n-propylbenzene concn in Los Angeles, CA air range from 1-3 ppb during Sep-Nov 1981 monitoring(5).|URBAN/SUBURBAN: The avg concns of n-propylbenzene in the air of Vienna, Austria during Oct 1986 to Feb 1987 monitoring were 0.6 ppb (background), 2.2 ppb (suburbs), and 4.8 ppb (streets)(1).

n-Propylbenzene occurs as a natural constituent in petroleum(1,3) and bituminous coal(2).

Incineration of organic, petroleum or coal wastes, and combustion of fuels will release n-propylbenzene to the atmosphere(1). General uses of asphalt and naphtha and use as a solvent will release n-propylbenzene to the environment(1). n-Propylbenzene is emitted in the exhaust from gasoline and diesel engines(2). Outboard motors and motor boats have been identified as sources of n-propylbenzene emissions to water(3,4). n-Propylbenzene can be released to the environment in leachates and vapor emissions from landfills(5,6).|n-Propylbenzene's production and use as a solvent and use in textile dyeing(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 955(SRC), determined from molecular connectivity indices(2), and measured values of 495 to 725(3,4) indicates that n-propylbenzene is expected to have low mobility in soil(SRC). Volatilization of n-propylbenzene from moist soil surfaces is expected to be an important fate process(7) given a Henry's Law constant of 1.05X10-2 atm-cu m/mole(5). The potential for volatilization of n-propylbenzene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 3.42 mm Hg(6). Biodegradation from soil may occur based on results from activated sludge studies(8).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 955(SRC), determined from molecular connectivity indices(2), as well as measured Koc values ranging from 495 to 725(3,4), indicate that n-propylbenzene is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(5) based upon a Henry's Law constant of 1.05X01-2 atm-cu m/mole(6). Using this Henry's Law constant and an estimation method(5), volatilization half-lives for a model river and model lake are 1 hr and 4 days, respectively(SRC). Volatilization half-lives of 1.3 to 19 days have been predicted for the Narraganset Bay near RI where volatilization is expected to be the major removal process(10). Aquatic hydrolysis is not an important fate process(SRC) due to the lack of hydrolyzable functional groups(5). According to a classification scheme(7), an estimated BCF of 138(SRC), from its log Kow of 3.69(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is moderate. Biodegradation from water may occur based on activated sludge studies, with theoretical BODs ranging from 21.8 to 43.7%(11,12).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-propylbenzene, which has a vapor pressure of 3.42 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-propylbenzene 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 2 days(SRC), calculated from its rate constant of 5.0X10-12 cu cm/molecule-sec at 25 °C(3). The detection of n-propylbenzene in rainwater samples(4) suggests that physical removal from the atmosphere by wet deposition is possible(SRC).

The rate constant for the vapor-phase reaction of n-propylbenzene with photochemically-produced hydroxyl radicals is 6.0X10-12 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 2 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). Aquatic hydrolysis is not an important fate process(SRC) due to the lack of hydrolyzable functional groups(3). n-Propylbenzene did not directly photolyze in experiments using pure aqueous seawater solutions and simulated sunlight(4); however, addition of an anthraquinone photosensitizer resulted in n-propylbenzene degradation and a formation of 1-phenyl-1-propanone, 1-phenyl-1-propanol, and benzaldehyde(4).

An estimated BCF of 138 was calculated for n-propylbenzene(SRC), using a log Kow of 3.69(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high.

741.31 L/kg|A Koc of 725 was measured for n-propylbenzene using a surface sediment collected from the Tamar estuary(1). A similar Koc of 676 was measured in a humic acid column via HPLC(2). Adsorption percentages ranging from 0.16 to 5.58% were measured in soil column studies using three different soil types and a sludge sample(3). Using a structure estimation method based on molecular connectivity indices(4), the Koc for n-propylbenzene can be estimated to be 955(SRC). According to a classification scheme(5), these estimated and measured Koc values suggest that n-propylbenzene is expected to have low mobility in soil.

The Henry's Law constant for n-propylbenzene is 1.05X10-2 atm-cu m/mole(1). This Henry's Law constant indicates that n-propylbenzene is expected to volatilize rapidly from water surfaces(2). 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 1 hour(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(SRC). Results of mesocosm studies simulating the Narragansett Bay indicate that volatilization is the major removal process from seawater(3); volatilization half-lives of 1.3-19 days were estimated for summer, spring and winter seasons(5). n-Propylbenzene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of n-propylbenzene from dry soil surfaces may exist(SRC) based upon it's vapor pressure of 3.42 mm Hg(4).

DRINKING WATER: Results of the USEPA Groundwater Supply Survey (finished water supplies that use groundwater sources) found that n-propylbenzene was detected in only one of 945 sources (concn of 0.98 ug/l in the one source) that were surveyed from throughout the US(1). Drinking water samples collected from Miami, FL and Cincinnati, OH during 1974 and 1975 had respective n-propylbenzene concns of 0.05 and 0.01 ug/l(2). A drinking water sample from Cincinnati, OH in Feb 1980 had a n-propylbenzene concn of 33 ng/l(3).|SURFACE WATER: The n-propylbenzene concn in Lake Constance varied from 4 to 132 ng/l; concns were observed to increase with increasing boat traffic(1). n-Propylbenzene was detected at levels up to 6 ug/l in river waters and their estuaries in Osaka City, Japan(2). During a 1992-1993 study, n-propylbenzene was not detected in surface water from a wetland in Orange County, FL which is adjacent to a landfill; it was detected in the 1989-1990 study at a concn of 0.08 ug/l(3).|GROUNDWATER: A well water sample collected near a landfill in Delaware had an n-propylbenzene concn of 0.5 ug/l(1). During a 1992-1993 study, n-propylbenzene was measured in ground water from a wetland in Orange County, FL which is adjacent to a landfill, ranging from not detected to 0.65 ug/l; it was detected in the 1989-1990 study (not detected to 0.08 ug/l)(3).|RAIN/SNOW: Trace levels (concn not reported) of n-propylbenzene were detected in rainwater collected in Los Angeles, CA on Mar 26, 1982(1).

n-Propylbenzene has been qualitatively identified as a volatile constituent of chickpea flour(1), roasted filbert nuts(2) and scrambled eggs(3). Level in peanut oil was less than 2% of the total volatiles(4).

Occupational exposure to n-propylbenzene occurs through dermal contact and inhalation of vapor(1); absorption takes place by inhalation and in small quantities through intact skin(1).|NIOSH (NOHS Survey 1972-1974) has statistically estimated that 16,823 workers are potentially exposed to n-propylbenzene in the USA(1). Mean air levels of 0.1-0.2 ppm n-propylbenzene were detected inside two US factories involved in spray painting and glueing(2). Air samples collected inside a tire re-treading factory in Italy contained n-propylbenzene levels of 0-15 ug/cu m(2); a shoe sole factory (vulcanization area) had a level of 30-300 ug/cu m(2). Occupational exposure to n-propylbenzene may occur through inhalation and dermal contact with this compound at workplaces where n-propylbenzene is produced or used. The general population is continually exposed to n-propylbenzene through inhalation since it has been detected frequently in the atmosphere(SRC).

n-Propylbenzene was qualitatively detected in 8 of 46 samples of human adipose tissue analyzed during the EPA National Human Adipose Tissue Survey in fiscal year 1982(1).
