Cyclohexanone is the organic compound with the formula (CH2)5CO.
Cyclohexanone and hydroxylamine will form cyclohexanone oxime, which can be converted via Beckmann rearrangement to caprolactam or reduced with sodium amalgam to cyclohexylamine.
Cyclohexanone is a colorless liquid, slightly soluble in water, but miscible with organic solvents.
Cyclohexanone is sold by chemical suppliers. It is sometimes found in PVC cements, along with THF.
Cyclohexanone has been used in the illicit production of phencyclidine (PCP) and its analogues and as such it may be subject to additional checks before purchase, depending on the country.
Cyclohexanone can also be produced by the oxidation of cyclohexane in air, typically using cobalt catalysts.
- Make caprolactam and Nylon 6
Cyclohexanone is irritant. With a flash point of 44 °C, it's not very flammable.
In closed bottles.
Should be mixed with a more flammable solvent and burned in an incinerator or outside.
