ACENAPHTHYLENE

EC / List no.: 205-917-1
CAS no.: 208-96-8
Mol. formula: C12H8

Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon.
The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit.
Acenaphthylene is a yellow solid.
Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence.

Occurrence
Acenaphthylene occurs as about 2% of coal tar. Acenaphthylene is produced industrially by gas phase dehydrogenation of acenaphthene.

Reactions
Hydrogenation gives the more saturated compound acenaphthene.
Chemical reduction affords the radical anion sodium or potassium acenaphthalenide, which is used as a strong reductant (E = -2.26 V vs FC).

Acenaphthylene functions as a ligand for some organometallic compounds.

Uses:
Polymerisation of acenaphthylene with acetylene in the presence of a Lewis acid catalyst gives electrically conductive polymers.
Acenaphthylene possesses excellent properties as an antioxidant in cross-linked polyethylene and ethylene-propylene rubber.
Thermal trimerization of acenaphthylene leads to decacyclene, which can be further processed to sulfur dyes.

Acenaphthylene is a colorless crystalline solid. Insoluble in water. Used in dye synthesis, insecticides, fungicides, and in the manufacture of plastics.

Acenaphthylene is a ortho- and peri-fused tricyclic hydrocarbon that occurs in coal tar.
Acenaphthylene is an ortho- and peri-fused polycyclic arene, a member of acenaphthylenes and an ortho- and peri-fused tricyclic hydrocarbon.

Acenaphthylene is a natural product found in Artemisia capillaris, Tuber canaliculatum, and Tuber borchii with data available.

Description
Acenaphthylene is a PAH with three aromatic rings.
Acenaphthylene 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.

Acenaphthylene is one of a group of chemicals called polycyclic aromatic hydrocarbons, PAHs for short.
PAHs are often found together in groups of two or more.
They can exist in over 100 different combinations but the most common are treated as a group of 15.
PAHs are found naturally in the environment but they can also be man-made.
PAHs are solid and range in appearance from colorless to white or pale yellow-green.
PAHs are created when products like coal, oil, gas, and garbage are burned but the burning process is not complete.
Very little information is available on the individual chemicals within the PAH group.
Most of the information available is for the PAH group as a whole.
Information specific to acenaphthylene is included in this fact sheet when available.

What is acenaphthylene used for?
Most of the PAHs are used to conduct research.
Like most PAHs, acenaphthylene is used to make dyes, plastics and pesticides

cenaphthylene is a polycyclic aromatic hydrocarbon that at first doesn't appear to follow all of the rules of aromaticity. We will learn why it is aromatic and how it is used.
Uses of Acenaphthylene
Acenaphthylene is used in making dyes and pigments that may have been used to dye your clothes. Since it isn't soluble in water it is useful in making dyes because it won't wash out when you wash your clothes.

Acenaphthylene is also used in making soaps, pesticides, and plastics.
Acenaphthylene can be toxic, which is why it is a useful pesticide.
And since it isn't soluble in water, it can act as the oil-binding molecule in soaps, which need to have one hydrophobic and one hydrophilic end.
