Uses
Uses in perfumery :
Less used than Linalyl acetate, it is still used for bergamot notes, for a contribution of naturalness, a sweet note and a green facet.
Year of discovery :
Data not available.
Natural availability :
Linalyl Propionate is found in Sweet Orange EO, Lemon EO, Bergamot EO. Its laevorotatory form is present in Lavender EO and Sage EO.
Isomerism :
Linalyl Propionate used in perfumery is a racemic mixture of its two enantiomers (R) and (S). Both have a similar smell. Geranyl Propionate and Lyral® are both constitutional isomers of Linalyl Propionate. The first is more citric and rosy, and the second has a transparent floral and aldehydic note.
Synthesis precursor :
Linalyl Propionate is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Linalyl Propionate is synthesized by an esterification reaction involving Linalol. This reaction may involve acetic acid, in the presence of a small amount of a concentrated strong acid, such as sulphuric acid. To improve the yield of this reaction, acetic anhydride or chloroacetic acid can be used instead of acetic acid.
