Nitrocyclohexane

Nitrocyclohexane is an organic compound with the molecular formula C6H11NO2. It is a colorless liquid, but degraded samples appear pale yellow. It once was produced commercially as a precursor to caprolactam.

==Preparation== It is prepared by reaction of nitrogen dioxide with cyclohexane, the so-called Nixian process. Cyclohexane is a convenient substrate because all twelve C-H bonds are equivalent, so mononitration does not give isomers (unlike the case of n-hexane).
