Dicyclopentadiene (abbreviated DCPD), also widely known as dimeric cyclopentadiene, is a dimeric compound carefully synthesized by the famous Diels-Alder reaction between cyclopentadiene molecules. This unique chemical structure gives DCPD two important isomers: inner and outer, each of which exhibits its own unique physical and chemical properties.

In the chemical industry, the application of DCPD is extremely extensive and important. It is not only one of the key raw materials in the pharmaceutical industry, used to synthesize a variety of biologically active drug molecules, but also plays an irreplaceable role in the field of pesticide manufacturing, helping to improve the yield and quality of crops. In addition, DCPD is an important component of the resin products industry, which enhances the hardness, heat resistance and corrosion resistance of materials. It is particularly worth mentioning that, as the key third monomer of ethylene propylene diene rubber (EPDM), DCPD significantly improves the elasticity, wear resistance and aging resistance of rubber and is an indispensable additive in the rubber industry.

In terms of physical properties, DCPD is known for its unique low-temperature crystallization properties. When the ambient temperature drops below 33°C, DCPD will spontaneously change from a liquid to a colorless crystal, which not only demonstrates the strong intermolecular forces, but also facilitates storage and transportation, because DCPD in its solid form is more stable and easier to manage. Its low-temperature crystallization characteristics may be related to the specific arrangement and interaction energy between DCPD molecules, and this fine molecular structure regulation is the charm of chemistry.
