C8 monomers

Cyclooctan (COAN)

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 saturated cyclic hydrocarbon cyclooctane (COAN) is a colorless liquid with a boiling point of 151°C and a freezing point of 12°C.
COAN is formed by catalytic hydrogenation of 1,5-cyclooctadiene, which is easily obtained by the dimerization of butadiene. 

COAN is very easily soluble in apolar substances. It can be used as a solvent whenever the special chemical inertness of saturated cyclic hydrocarbons is required.
