GOST no data
CAS 77-73-6

Dicyclopentadiene (DCPD, tricyclo[,6]dodeca-3,8-diene, bis(cyclopentadiene), cyclopentadiene dimer) is a colorless, waxy, flammable solid, with a camphor-like odor. It is soluble in petroleum ether, carbon tetrachloride, diethyl ether, acetone, acetic acid. It is slightly soluble in water. When above 100°C dicyclopentadiene decomposes to give cyclopentadiene.


Dicyclopentadiene is manufactured as a by-product in the steam cracking or from pyrolysis of naphtha and gas oils to ethylene and propylene.


Dicyclopentadiene is applied:

  • in adamantane and its derivatives manufacture;
  • in preparation of pesticides, insecticides, paints, varnishes, epoxy resin, flame retardants;
  • as an intermediate in production of hidraulic fluids, glutaraldehyde, antioxidants for rubber, fragnances;
  • in the production of hydrocarbon resins and unsaturated polyester resins;
  • in the production of EPDM (ethylene propylene diene monomer) elastomers, metallocenes;

  • Manufacturer(s) JSC "Nizhnekamskneftekhim" Inc.
