1-Cyclohexylethan-1-one Usage And Synthesis

Chemical Properties

Colorless liquid, soluble in alcohol, essential oils and perfume materials. Peculiar camphoraceous-sweet odor with a certain amount of floral tones. Although this chemical would primarily lend itself to perfume compositions in the Pine, Wood, Herbaceous and other non-floral types, it has a similarity to the harsh-floral types such as Hyacinth, etc. and its sweetness is sometimes classified as “musky”.

Uses

It can be used to produce acetoxycyclohexane. It is also used as a pharmaceutical intermediate.

Preparation

1-Cyclohexylethan-1-one is synthesized from cyclohexene, which is then hydrogenated to produce acetylcyclohexane.

Purification Methods

Dissolve acetylcyclohexane in Et2O, shake it with H2O, dry, evaporate and fractionate it under reduced pressure. [UV: Mariella & Raube J Am Chem Soc 74 518 1952, enol content: Gero J Org Chem 19 1960 1954 .] The semicarbazone has m 174o and the 2,4-dinitrophenylhydrazone has m 139-140o [Theus & Schinz Helv Chim Acta 39 1290 1956].
