Cyclooctene (COE)

The singly unsaturated cyclic hydrocarbon cyclooctene (COE) is a colorless liquid with a boiling point of 145°C.

COE is formed by selective hydrogenation of cyclooctadiene.

• we produce COE mainly for the manufacture of polyoctenamer by ring-opening polymerization.
• ozonolysis of COE yields suberic acid.
• various perfumes are obtained via a number of intermediate stages.
• thermolysis of COE yields 1,7-octadiene, which is also used industrially.
