Infobox disclaimer and references

Cyclohexanone is a six-carbon cyclic molecule with a ketone functional group. It is a colorless, oily liquid with an odor reminiscent of oil of peppermint and acetone. Over time, the color of the liquid changes to yellow. Cyclohexanone is slightly soluble in water (5-10 g/100 ml), but miscible with the most common organic solvents.

Cyclohexanone is employed as an industrial solvent and as activator in oxidation reactions. It is also used in the production of adipic acid, cyclohexanone resins, caprolactam and nylon 6.[3]
