(organic chemistry)
C10H17OH A combustible, colorless liquid with a lilac scent, derived from pine oil, soluble in alcohol, slightly soluble in water, boils at 214-224°C; used in medicine, perfumes, soaps, and disinfectants, and as an antioxidant, a flavoring agent, and a solvent; isomeric forms are alpha-, beta- and gamma-.



(also α-terpineol, l-p-menthen-8-ol), an unsaturated monocyclic alcohol of the terpene class. Terpineol occurs as colorless crystals and has a lilac odor. Its melting point is 36.9°C, and its boiling point 219°C. It is soluble in alcohol but not in water. Terpineol is contained in insignificant amounts in many essential oils, such as orange oil and neroli oil.

Terpineol is obtained industrially by dehydration of terpin hydrate or by direct hydration of the terpene hydrocarbons contained in turpentine oil. When obtained synthetically, it also contains the isomers β-and-γ-terpineol. Terpineol is used as an ingredient in perfumes and as a foaming agent in the flotation of ores of nonferrous metals. The esters of terpineol, such as terpinyl acetate, are also used in perfumes.
