Chemistry & Uses
Uses in perfumery :
Mainly used to add volume and freshness in white flowers accords.
Year of discovery :
Data not available.
Natural availability :
Found in Ambrette seed Oil (4%)
Isomerism :
Due to the presence of two double bonds in Farnesol, there are four pairs of diastereoisomers of Farnesyl acetate : (E,E), (Z,E), (E,Z), (Z,Z). In perfumery, we use a mix of all those isomers.
Synthesis precursor :
Farnesyl acetate is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
The synthesis of Farnesyl acetate is carried out by an esterification reaction between Acetic Acid and Farnesol. This reaction can be catalyzed by the presence of a small amount of a strong acid such as concentrated sulfuric acid. It can also be achieved by thanks to the use of acetic anhydride or chloroacetic acid instead of acetic acid.
Stability :
Esters may form their corresponding acid through time
