Description

Cyclopentadiene is a crystalline solid or a liquid (above 32°C) with a disagreeable, camphor-like odor. The Odor Threshold is 0.011 (detectable); 0.020 ppm (recognizable).
cyclopentadiene, although a stable molecule, has a strong tendency to form the more stable dimer dicyclopentadiene. This dimerisation already takes place at room temperature and its rate rapidly increases with elevated temperatures. This reaction however is reversible too; dicyclopentadiene

Dicyclopentadiene Use and Manufacturing

Used as the third monomer of ethylene propylene rubber. Used to synthesize ethylidene norbornene and also used as the third monomer of ethylene propylene rubber. It reacts with maleic anhydride to obtain norbornene dioic anhydride, which is used as a curing agent for epoxy resin. Dicyclopentadiene modifies tung oil, linseed oil, soybean oil, fish oil, etc., which can speed up drying and improve water and alkali resistance. Raw materials for the production of cyclopentadiene resin, paints and coatings. Used as high-energy fuel after hydrogenation. Mainly used in the fields of medicine, pesticides, synthetic resin, perfume, synthetic rubber, etc. It can be used to produce adamantane, 2-chloro-5-chloromethylpyridine, metallocene, glutaraldehyde, carbamate, epoxy resin curing agent, flame retardant, dicyclopentadiene chloride (insecticide) Wait. Cyclopentadiene and dicyclopentadiene can be used for self-polymerization to generate various grades of petroleum resin. The copolymer of cyclopentadiene or dicyclopentadiene and various monomers is the raw material for all-made rubber, resin ink, coating, adhesive and sizing. Dicyclopentadiene is chemically active and can be used for high-energy fuels. Through various chemical reactions, it can produce metal derivatives, epoxy resins, polymers, norbornene compounds, adamantane, glutaraldehyde, perfumes, medicines and other fine chemicals; used to prepare sulfadimethoxine , Sulfamethoxazole and other sulfa drugs
