一般描述

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.

应用

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
