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.
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
Non flammable
