cyclohexanonecyclohexanol

Cyclohexanonecyclohexanol is not a standard single chemical name. In most contexts, it may refer to either cyclohexanone or cyclohexanol as separate substances, or to a mixture containing both compounds. A well-known industrial mixture involving these two is KA oil, the combined product from the partial oxidation of cyclohexane used as a feedstock in nylon production. In literature, “cyclohexanonecyclohexanol” is more often encountered as shorthand for the pair or for their relationship in synthesis and processing, rather than as a distinct compound.

Cyclohexanone is a cyclic ketone with the formula C6H10O. It is a colorless to pale yellow liquid with a characteristic solvent odor and is moderately flammable. It is widely used as an industrial solvent and as an intermediate in the manufacture of adipic acid, caprolactam, and other nylon precursors. Commercially, cyclohexanone is produced by oxidation of cyclohexane, often together with cyclohexanol as KA oil, which is then processed further to reach desired products.

Cyclohexanol is a cyclic secondary alcohol with the formula C6H12O. It is a colorless to pale liquid used as a solvent and as an intermediate in chemical syntheses, including methods to produce cyclohexanone and various esters, plasticizers, and flavor/fragrance compounds. Cyclohexanol can be dehydrated to give cyclohexene and can be oxidized to cyclohexanone.

Safety and handling for both substances emphasize flammability and potential irritation. They should be used with appropriate ventilation, away from heat sources, and with personal protective equipment as recommended by material safety data sheets.
