化学的特性
Benzo(b)fluoranthene is a colorless, needleshaped
solid.
物理的性質
Colorless to pale yellow to yellow-orange needles or crystals from benzene, toluene, ethylbenzene
or acetic acid.
使用
Benz[e]acephenanthrylene is a polycyclic aromatic hydrocarbon that was detected in significant levels in airborne polluants, auto exhaust and tobacco and marijuana smoke.
定義
ChEBI: An ortho- and peri-fused polycyclic arene that consists of a benzene ring fused with a acephenanthrylene ring.
一般的な説明
Needles or yellow fluffy powder.
空気と水の反応
Insoluble in water.
反応プロフィール
BENZO(B)FLUORANTHENE can react with strong oxidizing agents. May react with electrophiles, peroxides, nitrogen oxides and sulfur oxides
危険性
Confirmed carcinogen.
健康ハザード
ACUTE/CHRONIC HAZARDS: When heated to decomposition, BENZO(B)FLUORANTHENE emits acrid smoke and irritating fumes.
火災危険
Flash point data for BENZO(B)FLUORANTHENE are not available; however, BENZO(B)FLUORANTHENE is probably combustible.
安全性プロファイル
Confirmed carcinogen
with experimental carcinogenic and
tumorigenic data. Mutation data reported.
When heated to decomposition it emits
acrid smoke and irritating fumes.
職業ばく露
There is no commercial production of
this compound. Benzo(b)fluoranthene is a chemical substance
formed during the incomplete burning of fossil fuel,
garbage, in cigarette smoke, or any organic matter and is
Benzofluoranthene 399
found in smoke in general; it is carried into the air, where
it condenses onto dust particles and is distributed into water
and soil and on crops. B(b)F is a PAH and a component of
coal tar pitch used in industry as a binder for electrodes. It
is also a component of creosote, which is used to preserve
wood. PAHs are also found in limited a mounts in bituminous
materials and asphalt used for paving, roofing, and
insulation. B(b)F has some use as a research chemical. It is
available from some specialty chemical firms in low quantities
(25 100 mg).
発がん性
Benzo[b]fluoranthenewas tested
for carcinogenicity by dermal application in mice in multiple
studies, intraperitoneal injection into mice
in multiple studies, and intrapulmonary
implantation into rats in one study. In all of these studies,
benzo[b]-fluoranthene exhibited a significant carcinogenic
activity.
環境運命予測
Biological. Ye et al. (1996) investigated the ability of Sphingomonas paucimobilis strain U.S.
EPA 505 (a soil bacterium capable of using fluoranthene as a sole source of carbon and energy) to
degrade 4, 5, and 6-ringed aromatic hydrocarbons (10 ppm). After 16 h of incubation using a
resting cell suspension, only 12.5% of benzo[b]fluoranthene had degraded. It was suggested that
degradation occurred via ring cleavage resulting in the formation of polar metabolites and carbon
dioxide.
Soil. The reported half-lives for benzo[b]fluoranthene in a Kidman sandy loam and McLaurin
sandy loam are 294 and 211 d, respectively (Park et al., 1990).
Photolytic. The atmospheric half-life was estimated to range from 1.43 to 14.3 h (Atkinson,
1987).
Chemical/Physical. Benzo[b]fluoranthene will not hydrolyze because it has no hydrolyzable
functional group (Kollig, 1993).
輸送方法
UN2811 Toxic solids, organic, n.o.s., Hazard
Class: 6.1; Labels: 6.1—Poisonous materials, Technical
Name Required.
不和合性
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions.
Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides.
廃棄物の処理
Residues and sorbent media
may be packaged in 17H epoxy-lined drums and disposed
of at an EPA-approved site. Destroy by permanganate oxidation,
high-temperature incineration with scrubbing equipment,
or microwave plasma treatment, if available.
Confirm disposal procedures with responsible environmental
engineer and regulatory officials.
