Methylcyclohexanone
From Wikipedia, the free encyclopedia
Methylcyclohexanones are a group of three isomers: 2-methylcyclohexanone, 3-methylcyclohexanone, and 4-methylcyclohexanone.[1] They can be viewed as derivative of cyclohexanone. They can be prepared by oxidation of methylcyclohexane as well as partial hydrogenation of the corresponding cresols. All are colorless liquids. The 2- and 3-isomers are chiral.
