Beschreibung
Acenaphthylene is a PAH with three aromatic rings. It is an intermediate chemical for
the manufacture of dyes, soaps, pigments, pharmaceuticals, insecticides, fungicides,
herbicides, plant growth hormones, naphthalic acids, naphthalic anhydride (pigments),
and acenaphthylene (resins) and is used to manufacture plastics. The largest emissions
of PAHs result from incomplete combustion of organic materials during industrial
processes and other human activities. These include (1) processing of coal, crude
oil, and natural gas, including coking, coal conversion, and petroleum refining; (2)
production of carbon blacks, creosote, coal tar, and bitumen; (3) aluminium, iron, and
steel production in plants and foundries; (4) heating in power plants and residences
and cooking; (5) combustion of refuse; (6) motor vehicle traffic; and (7) environmental
tobacco smoke.
Chemische Eigenschaften
Acenaphthylene is a flaky yellow crystalline powder or solid.
Physikalische Eigenschaften
Colorless to white prisms or crystalline plates from alcohol with an odor similar to coal tar or
aromatic hydrocarbons.
Verwenden
Acenaphthylene has been used to investigate the photodimerization of acenaphthylene in micellar and hydrogel media.
Definition
ChEBI: A ortho- and peri-fused tricyclic hydrocarbon that occurs in coal tar.
Allgemeine Beschreibung
Colorless crystalline solid. Insoluble in water. Used in dye synthesis, insecticides, fungicides, and in the manufacture of plastics.
Air & Water Reaktionen
Insoluble in water.
Reaktivit?t anzeigen
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as ACENAPHTHYLENE, 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
Acenapht hylene is i rritat i ng to t he sk i n a nd mucous membra nes of rabbits. Subc h ron ic oral
doses of acenaphthylene caused adverse effects to the kidneys, liver, blood, reproductive
system, and lungs of experimental animals. Prolonged period of inhalation at low doses
caused pulmonary effects like bronchitis, pneumonia, and desquamation of the bronchial
and alveolar epithelium in rats.
Sicherheitsprofil
Moderately toxic by intraperitonealroute. Mutation data reported. When heated todecomposition it emits acrid smoke and irritating fumes.
m?gliche Exposition
PAHs are compounds containing multiple benzene rings and are also called polynuclear aromatic hydrocarbons. Acenaphthylene is an aromatic hydrocarbon used in coal tar processing, as a dye intermediate; making insecticides, fungicides, plastics.
Environmental Fate
Biological. When acenaphthylene was statically incubated in the dark at 25 °C with yeast
extract and settled domestic wastewater inoculum, significant biodegradation with rapid
adaptation was observed. At concentrations of 5 and 10 mg/L, 100 and 94% biodegradation,
respectively, were observed after 7 d (Tabak et al., 1981). A Beijerinckia sp. and a mutant strain
were able to cooxidize acenaphthylene to the following metabolites: acenaphthenequinone and a
compound tentatively identified as 1,2-dihydroxyacenaphthylene. When acenaphthylene was
incubated with a mutant strain (Beijerinckia sp. strain B8/36) one metabolite formed which was
tentatively identified as cis-1,2-acenaphthenediol (Schocken and Gibson, 1984). This compound
also formed when acenaphthylene was deoxygenated by a recombinant strain of Pseudomonas
aeruginosa PAO1(pRE695) (Selifonov et al., 1996).
Bossert and Bartha (1986) reported that acenaphthylene in a Nixon sandy loam soil (1
g/kg) completely disappeared in <4 months. They concluded volatilization was more important
than biodegradation in the disappearance of acenaphthylene from soil.
Ozonation in water at 60 °C produced 1,8-naphthalene dialdehyde, 1,8-
naphthalene anhydride, 1,2-epoxyacenaphthylene, 1-naphthoic acid, and 1,8-naphthaldehydic acid
(Calvert and Pitts, 1966).

l?uterung methode
Dissolve acenaphthylene in warm redistilled MeOH, filter through a sintered glass funnel and cool to -78o to precipitate the material as yellow plates [Dainton et al. Trans Faraday Soc 56 1784 1960]. Alternatively it can be sublimed in vacuo. [Beilstein 5 H 625, 5 IV 2138.]
Inkompatibilit?ten
Keep away from ozone and strong oxidizing agents. 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
Waste disposal
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Product residues and sorbent media may be packaged in epoxy-lined drums, then destroyed by incineration, permanganate oxidation or microwave plasma treatment. The United States Environmental Protection Agency has investigated chemical precipitation for wastewater treatment
