What does dicyclopentadiene smell like?
Dicyclopentadiene is a colorless, sand-like powder with a disagreeable Camphor-like odor. It becomes a liquid over 90oF (32oC). It is used to manufacture pesticides, paints, varnishes, and other chemicals. * Dicyclopentadiene is on the Hazardous Substance List because it is cited by ACGIH, DOT, NIOSH and NFPA.
What is the cracking of cyclopentadiene?
To obtain cyclopentadiene monomer, commercial dicyclopentadiene is cracked by heating to around 180 °C. The monomer is collected by distillation, and used soon thereafter. It advisable to use some form of fractionating column when doing this, to remove refluxing uncracked dimer.
What is the structure of the dicyclopentadiene?
C10H12
Dicyclopentadiene/Formula
How is dicyclopentadiene made?
Dicyclopentadiene (DCPD) is produced as part of the separation process of crude C5 streams which is a by-product of ethylene manufacture. DCPD-containing products are also used in the production of hydrocarbon resins and unsaturated polyester resins.
Is dicyclopentadiene polar?
Dicyclopentadiene appears as a liquid with an acrid odor. Flash point 90°F. The vapors are irritating to the eyes and respiratory system….3.1Computed Properties.

Is DCPD aromatic?
The LX® petroleum hydrocarbon resin series is chemically inert and mixed aromatic/alicyclic in content. These products are high in unsaturation and low in molecular weight which benefits the end use/applications of printing inks, paints and coatings, rubber, adhesives and concrete cure compounds.
Why is cyclopentadiene reactive?
Cyclopentadiene is highly reactive in Diels–Alder reactions because only minimal out-of-plane distortion is required to achieve the transition state geometry compared with that of other cyclic and acyclic dienes. Asynchronous transition states have significant out-of-plane distortion about only one double bond.
What is the density of dicyclopentadiene?
980 kg/m³

What is DCPD resin?
DCPD resins are a type of unsaturated polyester resins broadly used for making composite components. Our customers combine the resin with specific peroxides, so a chemical reaction is initiated between resin backbone and the styrene, transforming the liquid into a hard and durable material.
Does cyclopentadiene Dimerize?
At room temperature cyclopentadiene slowly dimerizes, the exergonic ΔGº corresponding to an equilibrium constant of 106 in favor of the dimer.
Why is cyclopentadiene so acidic?
Therefore, Cyclopentadienyl anion is aromatic and highly stable. So, the tendency of cyclopentadiene to form its anion by losing its proton (from its fifth carbon atom) to get stabilized, is more. Therefore, cyclopentadiene is acidic due to the presence of conjugated double bonds and it is acidic than cyclopentane.
