DIHYDROTERPINEOL Usage And Synthesis
Aroma
Pleasant, floral, Lilac-type odor, softer, yet richer than Terpineol, not quite as lasting. Usually free from undesirable Pine-like notes.
Uses in Perfume
Finds some use of dihydroterpineol in perfumery as a modifier for Terpineol in Lilac, Appleblossom, Hyacinth and many other floral fragrances, particulady for low-cost household fragrances, also in New Mown Hay, Fougere, etc. for soaps and detergents.
Physical properties
Needle-like crystals. M.P. 35 °C. B.P. 210 °C. Sp.Gr. 0.90 (liquid).
Uses
Dihydro-α-terpineol is used as a bronchodilator for treatment of asthma, bronchitis, and other respiratory diseases. It is also a useful deodorant, food additive, and analgesic agent.
Production Methods
Dihydroterpineol can be produced:
1) by hydrogenation of alpha-Terpineol with
Platinum catalyst (this leads to a fairly
pure trans-Dihydroterpineol).
2) by heating Menthol and Terpineol with a
catalyst (this produces Menthone as a by-product).
