Cyclohexane is a six carbon ring (ie, "cyclo") molecule. Cyclohexane is technically a hexane, but the market dynamics are very different.
While cyclohexane is technically a hexane, cyclohexane is not distilled from crude oil, but rather produced from benzene. Cyclohexane is primarily consumed to make nylon, but is also used as an organic solvent in the lab.
