Tetrahydrolinalool Usage And Synthesis

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

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.

Definition

ChEBI: A fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7. Metabolite observed in cancer metabolism.

Aroma threshold values

Aroma characteristics at 1%: floral linalool-like with a fatty citrus rind and tea-like nuance.

Taste threshold values

Taste characteristics at 1 to 15 ppm: clean and fresh, floral, tea-like with citrus and herbal nuances.

General Description

The chlorooxidation of 3,7-dimethyl-3-octanol (tetrahydrolinalool) was studied.

Flammability and Explosibility

Non flammable
