Chemical Properties |
Tetrahydrolinalool is a constituent of honey aroma. It is a colorless liquid with a linalool-like odor that is slightly fresher but distinctly weaker than that of linalool. Tetrahydrolinalool is prepared by catalytic hydrogenation of linalool and is used as a substitute for the less stable linalool in perfuming aggressive media. |
|
Chemical Properties |
Tetrahydrolinalool has a sweet, oily, floral odor (more so than linalool) with a citrus floral taste. |
|
Chemical Properties |
Clear colorless liquid |
|
Uses |
Perfumery, flavoring. |
|
Preparation |
By hydrogenation of dl-linalool in the presence of palladium black according to Barbier and Lacquin; also from magnesium ethyl bromide and isoamylketone, or by hydrogenation of 2,6-dimethyl-2-octen-6-ol in the presence of nickel at 100°C; optically active and racemic forms are expected because of the structure of this product. |
|
Definition |
