Usage of Dicyclopentadiene

Dicyclopentadiene(DCPC for short) is a dimer of cyclopentadiene. By first heating, cyclopentadiene is copolymerized into dicyclopentadiene, and dicyclopentadiene Chemicalbook is separated from other light components (boiling point <45°C) by distillation, and then other required dienes are separated by solvent extraction, Monoolefin and saturated hydrocarbon components. High-purity dicyclopentadiene is a colorless crystal at room temperature. When it contains impurities, it is a light yellow oily liquid with a pungent camphor smell. It is insoluble in water and soluble in organic solvents such as alcohol and ether.


Dicyclopentadiene uses

1. Dicyclopentadiene can be used as the third component of ethylene-propylene binary copolymer (EPDM);

2. Dicyclopentadiene can be used as a raw material for the synthesis of ethylidene norbornene (ENB);

3. Dicyclopentadiene reacts with maleic anhydride to obtain norbornene dianhydride, which is used as a raw material for epoxy resin curing agent, polyester resin, alkyd resin and insecticide;

4. Hexachloride of cyclopentadiene - hexachlorocyclopentadiene, hydrogenated phthalic anhydride of hexachloride endomethylene obtained by reacting with maleic anhydride, used as a flame retardant for synthetic resins;

5. Dicyclopentadiene can be used in the modification of tung oil, linseed oil, soybean oil, fish oil, etc., which can speed up drying and improve water and alkali resistance;

6. Dicyclopentadiene resin can be used as rubber adhesive, pressure-sensitive adhesive, hot-melt adhesive, ink, coating, etc.;

7. Dicyclopentadiene oxide can be used as injection molding and lamination molding resin;

8. Cyclopentene obtained by partial hydrogenation of cyclopentadiene is repolymerized to obtain 1,5-trans-polycyclopentene;

9. Cyclopentadiene is the raw material for the production of aldrin and dildrin pesticides;

10. Cyclopentadiene is also used in drug synthesis, such as methyl α-cyclopentadienyl mandelate, the intermediate of Wei Changle.

11. After hydrogenation, it can be used as high-energy fuel.

The above is the introduction of the use of dicyclopentadiene. If you are interested in dicyclopentadiene, please come to consult.
