Linalyl propionate

Other comments :

Can contain Linalool traces.
Its smell is greener and less agrestic than the one of Linalyl acetate.

Stability :

Esters may form their corresponding acid through time

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.

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.

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.

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.
