Dicyclopentadiene

Dicyclopentadiene (DCPD), also known as 4,7-methano-1H-indene, is a chemical compound with the formula C10H12. It is a colorless, flammable liquid with a camphor-like odor. Dicyclopentadiene is produced by steam cracking of naphtha and gas oils to produce ethylene. The primary use of dicyclopentadiene is in the production of cyclopentadiene and its derivatives.

Chemical Structure

Dicyclopentadiene consists of two fused cyclopentene rings. The molecule is unsaturated, with four pi bonds. The structure of dicyclopentadiene is shown below:

Production

Dicyclopentadiene is produced as a byproduct of the steam cracking of naphtha and gas oils to produce ethylene. The dicyclopentadiene is then separated from the other hydrocarbons by distillation. The process is highly efficient, with yields of up to 95%.

Uses

The primary use of dicyclopentadiene is in the production of cyclopentadiene and its derivatives. These compounds are used in the manufacture of a variety of products, including resins, adhesives, and paints. Dicyclopentadiene is also used as a monomer in the production of polydicyclopentadiene, a high-performance engineering plastic.

Health Effects

Exposure to dicyclopentadiene can cause irritation to the eyes, skin, and respiratory tract. It may also cause nausea, headache, and dizziness. Long-term exposure can lead to kidney and liver damage.

Safety

Dicyclopentadiene is a flammable liquid and should be stored and handled with care. It should be kept away from heat, sparks, and open flames.
