Vinylcyclohexene (VCH)

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.
