Cyclohexene

Cyclohexene is a colorless clear liquid cycloalkene with an intense aversive characteristic sharp smell reminiscent of an oil refinery.

It is not very stable upon long term storage with exposure to light and air and should be distilled before use to eliminate peroxides. A common experiment among beginning organic chemistry students is the acid catalyzed dehydration of cyclohexanol with distillative removal of the resulting cyclohexene from the reaction mixture:





Refractive Index: 1.4465 Critical temperature: 287.2 °C (560.4 K)

Uses
Cyclohexene is used in manufacturing of adipic acid, hexahydrobenzoic acid, maleic acid, cyclohexanol and cyclohexeneoxide. Further it is used as a solvent.
