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.

Definition

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

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.

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

Nonflammable
