Anwendungen

Cyclohexene is used as a solvent. It is employed as a precursor to caprolactam, adipic acid, maleic acid, dicyclohexyladipate and cyclohexeneoxide. It is used as an intermediate for the production of cyclohexanol and cyclohexeneoxide.

Bemerkungen

Incompatible with strong oxidizing agents.
