Chemical Properties
Clear colorless liquid
Chemical Properties
Tetrahydrolinalool has a sweet, oily, floral odor (more so than linalool) with a citrus floral taste.
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.
Occurrence
Reported found in Virginia tobacco.
Uses
Perfumery, flavoring. As a major component in delicate floral fragrance types, Muguet, Lily, Lilac, Mimosa, variations of Rose and Jasmin, etc. Tetrahydrolinalool has repeatedly confirmed its pleasant effects and good stability. It is also used in Lavender compositions, Chypres, Fougeres, etc., as a modifier/blender, and its mild odour makes it almost universally applicable. Traces of the alcohol are used in flavour compositions for imitation Citrus, fruit complexes, berry flavours and certain Liqueur flavours. The concentration in the finished product will usually be as low as 1 to 6 ppm.
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.
