C8 monomers

Vinylcyclohexene (VCH)

Evonik is a leader in the production of industrially available cyclic C8 monomers and offers the four most important synthetic chemicals 1,5-cyclooctadiene (COD), cyclooctene (COE), cyclooctane (COAN), and 4-vinylcyclohex-1-ene (VCH).

Building blocks for your synthesis

The doubly unsaturated cyclic hydrocarbon 4-vinylcyclohexene (VCH) is a colorless liquid with a boiling point of 126°C and a pungent odor.

- VCH is formed by dimerization of butadiene.
- VCH is a precursor in the production of flame retardants.
- It is hydrogenated to ethylcyclohexane, a solvent for apolar substances.

It also serves as an intermediate in the synthesis of specialty chemicals.
