Dicyclopentadiene, abbreviated
DCPD, is a
chemical compound with formula C
10H
12. At room temperature, it is a white crystalline solid with a
camphor-like odor. Its
energy density is 10,975
Wh/l. Dicyclopentadiene is coproduced in large quantities in the steam cracking of
naphtha and
gas oils to
ethylene. The major use is in
resins, particularly, unsaturated polyester resins. It is also used in inks, adhesives, and paints.
