Use
Acenaphthylene is a polycyclic aromatic hydrocarbon (PAH) with three aromatic rings. It is
used to manufacture plastics. Intermediate for dyes, soaps, pigments, pharmaceuticals, insec-
ticide, fungicide, herbicide, and plant growth hormones. Intermediate for naphthalic acids,
naphthalic anhydride (intermediate for pigments), and acenaphthylene (intermediate for res-
ins). The largest emissions of PAH result from incomplete combustion of organic materials
during industrial processes and other human activities. These include (a) processing of coal, crude oil, and natural gas, including coal; (b) coking, coal conversion, petroleum refi
ning, and
production of carbon blacks, creosote, coal-tar, and bitumen; (c) aluminium, iron, and steel
production in plants and foundries; (d) heating in power plants and residences and cooking;
(e) combustion of refuse; (f) motor vehicle traffi
c; and (g) environmental tobacco smoke.
