| Hazard Information | Back Directory | [General Description]
A crystalline solid. Denser than water and insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Toxic by ingestion. Used to make other chemicals. | [Reactivity Profile]
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as CHRYSENE(218-01-9), 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. | [Air & Water Reactions]
Insoluble in water. | [Hazard]

Identified in Kuwait and South Louisiana crude oils at concentrations of 6.9 and 17.5
ppm, respectively (Pancirov and Brown, 1975). Also present in high octane gasoline (6.7 mg/kg),
bitumen (1.64–5.14 ppm), gasoline exhaust (27–318 μg/m3), cigarette smoke (60 μg/1,000
cigarettes), and South Louisiana crude oil (17.5 ppm) (quoted, Verschueren, 1983). Also detected
in fresh motor oil (56 mg/L), used motor oil (10.17 mg/L) (Pasquini and Monarca, 1093).
Detected in groundwater beneath a former coal gasification plant in Seattle, WA at a
concentration of 10 μg/L (ASTR, 1995). The concentration of chrysene in coal tar and the
maximum concentration reported in groundwater at a mid-Atlantic coal tar site were 3,600 and 0.0063 mg/L, respectively (Mackay and Gschwend, 2001). Based on laboratory analysis of 7 coal
tar samples, chrysene concentrations ranged from 620 to 5,100 ppm (EPRI, 1990). Chrysene was
also detected in 9 commercially available creosote samples at concentrations ranging from 19 to
620 mg/kg (Kohler et al., 2000).
Identified in high-temperature coal tar pitches used in roofing operations at concentrations
ranging from 2,600 to 88,000 mg/kg (Arrendale and Rogers, 1981; Malaiyandi et al., 1982).
Chrysene was detected in asphalt fumes at an average concentration of 115.67 ng/m3 (Wang et
al., 2001).
Under atmospheric conditions, a low rank coal (0.5–1 mm particle size) from Spain was burned
in a fluidized bed reactor at seven different temperatures (50 °C increments) beginning at 650 °C.
The combustion experiment was also conducted at different amounts of excess oxygen (5 to 40%)
and different flow rates (700 to 1,100 L/h). At 20% excess oxygen and a flow rate of 860 L/h, the
amount of chrysene emitted ranged from 127.9 ng/kg at 950 °C to 1,186.0 ng/kg at 750 °C. The
greatest amount of PAHs emitted were observed at 750 °C (Mastral et al., 1999). | [Environmental Fate]
Biological. When chrysene was statically incubated in the dark at 25 °C with yeast extract and
settled domestic wastewater inoculum, significant biodegradation with varied adaptation rates was
observed. At concentrations of 5 and 10 mg/L, 59 and 38% biodegradation, respectively, were
observed after 28 d (Tabak et al., 1981).
Soil. The reported half-lives for chrysene in a Kidman sandy loam and McLaurin sandy loam
are 371 and 387 d, respectively (Park et al., 1990).
Surface Water. In a 5-m deep surface water body, the calculated half-lives for direct
photochemical transformation at 40 °N latitude, in the midsummer during midday were 13 h and
68 d with and without sediment-water partitioning, respectively (Zepp and Schlotzhauer, 1979).
Photolytic. Based on structurally related compounds, chrysene may undergo photolysis to yield
quinones (U.S. EPA, 1985) and/or hydroxy derivatives (Nielsen et al., 1983). The atmospheric
half-life was estimated to range from 0.802 to 8.02 h (Atkinson, 1987). Behymer and Hites (1985)
determined the effect of different substrates on the rate of photooxidation of chrysene using a
rotary photoreactor. The photolytic half-lives of chrysene using silica gel, alumina, and fly ash
were 100, 78, and 38 h, respectively. | [storage]
Color Code—Green: General storage may be used.Prior to working with chrysene you should be trained on itsproper handling and storage. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Sources of ignition, such assmoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could createa potential fire or explosion hazard. | [Purification Methods]
Purify chrysene by chromatography on alumina from pet ether in a darkened room. Its solution in *C6H6 is passed through a column of decolorising charcoal, then crystallised by concentrating the eluate. It has also been purified by crystallising from *C6H6 or *C6H6/pet ether, and by zone refining. [Gorman et al. J Am Chem Soc 107 4404 1985]. It is freed from 5H-benzo[b]carbazole by dissolving it in N,N-dimethylformamide and successively adding small portions of alkali and iodomethane until the fluorescent colour of the carbazole anion no longer appears when alkali is added. The chrysene (and alkylated 5H-benzo[b]carbazole) separate on addition of water. Final purification is by crystallisation from ethylcyclohexane and/or from 2-methoxyethanol [Bender et al. Anal Chem 36 1011 1964]. It can be sublimed in a vacuum. [Beilstein 5 IV 2554.] | [Toxicity evaluation]
Generally, disposal of PAH from the industrial plants, accidental
release from the containers, smoke from plant,
combustion, or automobile exhaust causes chrysene and other
PAHs to enter the environment. Because of the poor water
solubility and low vapor pressure, chrysene has limited chance
to get washed away or evaporate in the environment. Therefore,
it remains immobile in soils. If exposed to water, it gets
absorbed on the particulate matters and either float or sediment
on the riverbed. The rate of biodegradation in soil ranges
from 77 to 387 days depending on the soil type.Chrysene does
not undergo hydrolysis due to the lack of hydrolyzable functional
groups. However, it undergoes photochemical oxidations
when exposed to the environment. Dihydrodiol is the
common degradation product of chrysene. Half-life of degradation of chrysene, absorbed to soot particles and
exposed to sunlight in air containing 10 ppm nitrogen oxides is
26 days. The National Research Council (NRC 1983) noted
that the PAHs adsorbed to soot particles are more resistant to
photochemical reactions than pure compounds. |
| Questions And Answer | Back Directory | [Description]
Chrysene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings. Some of its derivatives such as electroluminescent 3, 6, 9, 12-tetrasubstituted chrysenes are useful in electroluminescent applications such as being used in the organic light emitting dioxide (OLED). They are also relates to electronic devices in which the active layer includes such a chrysene composition. Chrysene is a potential carcinogen.
