Dicyclopentadiene

Alias: BHT as stabilizer; 3,5-di-tert-butyl-4-hydroxytoluene

Overview:

Dicyclopentadiene is a dimer of cyclopentadiene. By heating first, cyclopentadiene is copolymerized into dicyclopentadiene, dicyclopentadiene is separated by distillation from other light components (boiling point < 45 ℃), and then other required diene, monoene and saturated hydrocarbon components are extracted by solvent. High purity dicyclopentadiene is a colorless crystal at room temperature. When it contains impurities, it is a light yellow oily liquid with pungent camphor taste. It is insoluble in water and soluble in organic solvents such as alcohol and ether.
