Chemistry & Uses
Uses in perfumery :
Acetoin is used in buttery notes.
Year of discovery :
Data not available.
Natural availability :
Acetoin can be obtained following the fermentation of molasses, among other products.
Isomerism :
Acetoin has an asymmetric carbon. Its two enantiomers (R) and (S) have a similar smell. In perfumery, it is the racemic mixture of this molecule that is used. Ethyl acetate is a constitutional isomer of Acetoin. These two molecules, however, have a very different smell, as Ethyl acetate has a solvent smell and is more fruity.
Synthesis precursor :
Acetoin is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Acetoin is synthesized by a partial oxidation of 2,3-butanediol.
Stability :
Stable in perfumes and diverse functional bases
Other comments :
Acetoin is less used than Diacetyl to bring a buttery facet. It has a softer facet and is less powerful.
