3-METHYL-2-PENTANONE Chemical Properties,Usage,Production

Chemical Properties

3-Methyl-2-pentanone is a colorless liquid with an odor reminiscent of peppermint.

Uses

3-Methyl-2-pentanone is used as a solvent and as an intermediate for syntheses of pharmaceuticals.

Synthesis Reference(s)

The Journal of Organic Chemistry, 41, p. 1939, 1976 DOI: 10.1021/jo00873a011
Tetrahedron Letters, 16, p. 4453, 1975 DOI: 10.1016/S0040-4039(00)91090-6

Synthesis

2-Butanone undergoes basecatalyzed aldolization with acetaldehyde to form 4-hydroxy-3-methylpentan-2-one. Acidcatalyzed dehydration to 3-methyl-3-penten-2- one is followed by hydrogenation over a palladium catalyst to give 3-methyl-2-pentanone.
