General description

Cyclohexanone is a cycloalkanone. It is an industrially important intermediate. It is useful for the preparation of raw materials for various chemical intermediates, such as caprolactam for nylon 6 and adipic acid for nylon 66 synthesis of nylon. It can be synthesized industrially by either the oxidation of cyclohexane or the hydrogenation of phenol.

Application

Cyclohexanone may be used for the following syntheses:
  • vitamin A
  • 2-cyclohexylidene cyclohexanone via Aldol condensation reaction
  • 2-cyclohexenyl cyclohexanone via Aldol condensation reaction
  • bis-(arylmethylidene)cycloalkanones by cross-aldol condensation with aldehydes

Aldol Condensation Reaction

The aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872.
