| | 1,12-BENZOPERYLENE Usage And Synthesis |
| Chemical Properties | solid | | Uses | An n-channel organic semiconductor. | | Uses | Research chemical. Derived from industrial and experimental coal gasification operations
where the maximum concentration detected in coal tar streams was 2.7 mg/m3 (Cleland, 1981). | | Definition | ChEBI: Benzo[ghi]perylene is an ortho- and peri-fused polycyclic arene. | | General Description | Colorless to white crystalline solid. Water insoluble. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 1,12-BENZOPERYLENE, 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. | | Health Hazard | Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. | | Health Hazard | There is very little information available inthe literature on the toxicity of this compound. Benzo[g,h,i]perylene has low oraltoxicity. On the basis of its structural similarities with other carcinogenic polynucleararomatics, this compound is expected to show carcinogenic properties. Such evidence, however, is inadequate at the moment. A histidinereversion–Ames test for mutagenicity gaveinconclusive results. | | Fire Hazard | Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. | | Safety Profile | Questionable carcinogen.Mutation data reported. When heated to decomposition itemits acrid smoke and irritating fumes. | | Carcinogenicity | Subcutaneous or dermal administration
(repeated administration and initiation–promotion
protocols) of benzo[ghi]perylene to mice gave negative
results. Intrapulmonary injection into rats gave results considered
to be inadequate for evaluation. | | Source | Drinking water standard: No MCLGs or MCLs have been proposed (U.S. EPA, 2000).
Detected in 7 of 8 diesel fuels at concentrations ranging from 0.008 to 0.35 mg/L with a
mean value of 0.113 mg/L (Westerholm and Li, 1994). Identified in Kuwait and South Louisiana
crude oils at concentrations of <1 and 1.6 ppm, respectively (Pancirov and Brown, 1975) and in
fresh motor oil (120 μg/kg) and used motor oil (108.8–289.4 mg/kg) (quoted, Verschueren, 1983).
Detected in asphalt fumes at an average concentration of 22.76 ng/m3 (Wang et al., 2001).
The concentration of benzo[ghi]perylene in coal tar and the maximum concentration reported in
groundwater at a mid-Atlantic coal tar site were 1,200 and 0.002 mg/L, respectively (Mackay and
Gschwend, 2001). Based on laboratory analysis of 7 coal tar samples, benzo[ghi]perylene
concentrations ranged from ND to 1,900 ppm (EPRI, 1990). Benzo[ghi]perylene was reported in a
high-temperature coal tar pitch used in roofing at concentrations ranging from 754 to 3,980 mg/kg
(Malaiyandi et al., 1982).
Nine commercially available creosote samples contained benzo[ghi]perylene at concentrations
ranging from 1 to 45 mg/kg (Kohler et al., 2000).
Schauer et al. (2001) measured organic compound emission rates for volatile organic
compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds
from the residential (fireplace) combustion of pine, oak, and eucalyptus. The particle-phase
emission rates of benzo[ghi]perylene were 0.437 mg/kg of pine burned and 0.173 mg/kg of
eucalyptus burned.
Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without
catalytic converters were 0.26 and 10.7 μg/km, respectively (Schauer et al., 2002). | | Environmental fate | Biological. Based on aerobic soil die away test data at 10 to 30 °C, the estimated half-lives
ranged from 590 to 650 d (Coover and Sims, 1987).
Groundwater. Based on aerobic soil die away test data at 10 to 30 °C, the estimated half-lives
ranged from 3.23 to 3.56 yr (Coover and Sims, 1987).
Photolytic. The atmospheric half-life was estimated to range from 0.321 to 3.21 h (Atkinson,
1987). Behymer and Hites (1985) determined the effect of different substrates on the rate of
photooxidation of benzo[ghi]perylene using a rotary photoreactor. The photolytic half-lives of
benzo[ghi]perylene using silica gel, alumina, and fly ash were 7.0, 22, and 29 h, respectively.
Chemical/Physical. At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC
adsorption capacities were 10.7, 4.6, 2.0, and 0.85 mg/g, respectively (Dobbs and Cohen, 1980). | | Purification Methods | It forms light green crystals on recrystallisation from *C6H6 or xylene and sublimes at 320-340o/0.05mm [UV: Hopff & Schweizer Helv Chim Acta 42 2315 1959, Clar Chem Ber 65 846 1932, Fluoresc. Spectrum: Bowen & Brocklehurst J Chem Soc 3875 1954]. It also recrystallises from propan-1-ol [Altman & Ginsburg J Chem Soc 466 1959]. The 1,3,5-Trinitrobenzene complex has m 310-313o (deep red crystals from *C6H6), the picrate has m 267-270o (dark red crystals from *C6H6), and the styphnate (2,4,6-trinitroresorcinol complex) has m 234o (wine red crystals from *C6H6).
