Preparation method:
Extraction from coal tar: coal tar contains a certain amount of cyclopentadiene, which can be separated by distillation and other methods, and then dimerized under certain conditions to obtain dicyclopentadiene.
Extraction from petroleum cracking C5 distillate: petroleum cracking C5 distillate contains cyclopentadiene, which is dimerized to generate bicyclopentadiene by heating, and then separated and purified by distillation, extraction and other methods.
Application field:
Synthetic resins: dicyclopentadiene can be copolymerized with other monomers to synthesize a variety of resins with excellent properties, such as unsaturated polyester resin, epoxy resin, polyimide resin, etc. These resins are widely used in coatings, adhesives, composite materials and other fields.
Synthetic rubber: dicyclopentadiene can be used as a monomer of synthetic rubber, and other monomers to synthesize rubber with special properties, such as ethylene propylene rubber, butyl rubber, etc.
Spices: dicyclopentadiene can be synthesized through a series of reactions, such as cyclopentenone spices, ionone spices, etc. These fragrances have a unique aroma and are widely used in perfume, cosmetics, food and other fields.
Pharmaceutical intermediates: dicyclopentadiene can be used as a pharmaceutical intermediate to synthesize some biologically active compounds, such as anticancer drugs and antiviral drugs.
Other fields: dicyclopentadiene can also be used in the preparation of pesticides, dyes, inks and so on.
