描述

一般說明

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.[1][2] It can be synthesized industrially by either the oxidation of cyclohexane or the hydrogenation of phenol.[1][3][4]

應用

Cyclohexanone may be used for the following syntheses:

• vitamin A[5]
• 2-cyclohexylidene cyclohexanone via Aldol condensation reaction[6]
• 2-cyclohexenyl cyclohexanone via Aldol condensation reaction[6]
• bis-(arylmethylidene)cycloalkanones by cross-aldol condensation with aldehydes[7]
