Methyl hexyl ketone

Other comments :

Comparing it with Methyl Hexyl Ketone, the latter has a more earthy than mushroom smell, as does Methyl Amyl Ketone.

Stability :

Stable in perfumes and diverse functional bases

Uses in perfumery :

Methyl Hexyl Ketone is used in hay notes and fougere accords. Allows to enhance a cheesy aspect, especially in fruity notes.

Year of discovery :

Data not available.

Isomerism :

When the ketone function of Methyl Hexyl Ketone is relocated, the smell can radically change. For example, Ethyl Pentyl Ketone has a more lavender and mushroom smell. 1,3 Octenol and Aldehyde C-8 are constitutional isomers of Methyl Hexyl Ketone. Their smell is closer to mushroom or more aldehyde.

Synthesis precursor :

In contrast to its synthesis, a hydrogenation of Methyl Hexyl Ketone converts it to 2-octanol, which also has an olfactory interest.

Natural availability :

Methyl Hexyl Ketone is present in Lavandin EO, Ruta graveolens and several foods such as certain cheeses. Therefore, it can be extracted from Lavandin EO. However, synthetic Methyl Hexyl Ketone in most often used in perfumery.

Synthesis route :

Methyl Hexyl Ketone is synthesized by a catalytic oxidation of 2-octanol. This oxidation can be done in the presence of sodium hypochlorite at a high temperature, for example.
