General description

Cyclohexanone, a colorless liquid is a cyclic ketone. It is an important building block for the synthesis of a variety of organic compounds. Majority of the cyclohexanone synthesized is utilized as an intermediate in the synthesis of nylon. One of the methods reported for its synthesis is by the palladium catalyzed hydrogenation of phenol. The kinetics of the oxidation reaction of cyclohexanone has been studied in a fused silica jet stirred reactor. The Meerwein–Ponndorf–Verley reduction of cyclohexanone has been reported.

Application

  • Application in polymer physicochemical properties: Research highlights the utility of cyclohexanone in developing Poly(vinylidene fluoride) aerogels, emphasizing its role in manipulating polymorphic structures to tune physicochemical characteristics for advanced applications (Suresh et al., 2024).
