Uses
Uses in perfumery :
Cinnamyl acetate is used in reproductions of hyacinth, rosy and woody-spicy notes, to provide a green and balsamic effect.
Year of discovery :
Data not available.
Natural availability :
Cinnamyl acetate can be found in small quantity in some plant extracts such as Ylang-Ylang Extra EO (and other ylang fractions), Laurel EO and Cinnamon Leaf EO, as well as Narcissus Absolute, among others.
Isomerism :
Cinnamyl acetate has two diastereoisomers, due to the presence of a double bond in its structure. The (E) isomer of Cinnamyl acetate has an even sweeter smell than the (Z) isomer. Anyway, both have a similar smell, which explains the use of a racemic mixture of the two isomers in perfumery.
Synthesis precursor :
Cinnamyl acetate is not a precursor of the synthesis of another compound of olfactive interest.
Synthesis route :
Cinnamyl acetate is synthesized by an esterification reaction between Cinnamyl Alcohol and acetic acid. This reaction is catalyzed by the presence of a small quantity of a strong acid such as sulphuric acid. In addition, the yield of this reaction can be improved by the use of acetic anhydride or chloroacetic acid, rather than acetic acid.
