What is alpha-Terpineol?
Description
α-Terpineol is a terpene alcohol that is found in natural oils such as pine oil and petitgrain (the oil from the bitter orange tree). It is the most common of four structural isomers; the others are β-, γ-, and 4-terpineol. It should not be confused with terpinol, the hydrate of terpin, a terpene diol.
α-Terpineol is a racemic mixture of (R)-(+)- and (S)-(–)-enantiomers. Both are found in nature; but the article of commerce, which is usually synthesized from α-pinene, is the racemate. In 1903, German chemists H. Waldbaum and O. Hüthig isolated the (+)-stereoisomer from petitgrain. Four years later, J. E. Teeple of New York City separated its enantiomer from?long-leaf pine oil.
The lilac-like aroma of α-terpineol makes it a desirable ingredient for perfumes and cosmetics. This time of year, people burn α-terpineol-scented candles for their piney scent. Whatever your favorite aroma during the holidays, enjoy the season!
