Бензо[гhi]перилен

Химические свойства

solid

Использование

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).

Общее описание

Colorless to white crystalline solid. Water insoluble.

Реакции воздуха и воды

Insoluble in water.

Профиль реактивности

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.

Угроза здоровью

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.

Пожароопасность

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Профиль безопасности

Questionable carcinogen.Mutation data reported. When heated to decomposition itemits acrid smoke and irritating fumes.

Канцерогенность

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.

Экологическая судьба

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).

Методы очистки

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).
