Chemistry & Uses
Uses in perfumery :
Diacetyl is not so often used in perfumery. Used in vanillic, caramel and fruity notes for a butter, natural and pastry effect.
Year of discovery :
Data not available.
Natural availability :
Diacetyl is contained in many fruits and in butter, among others. It is extracted from certain fruits in its natural state.
Isomerism :
Diacetyl does not have any isomer used in perfumery.
Synthesis precursor :
Diacetyl is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Diacetyl is synthesized in several possible ways. The most common is the catalytic dehydrogenation (with copper and chromium) of 2,3-butanediol. Biochemical pathways are also widely used on an industrial scale.
Stability :
Stable in perfumes and diverse functional bases
Other comments :
In comparision to Acetoin, Diacetyl is much more used in perfumery. It also is more powerful.
