Chemical Properties

(?)-α-Phellandrene is a colorless liquid with a citrus odor and a slight peppery note. It is isolated, for example, from Eucalyptus dives oil. Pinenes are widespread, naturally occurring terpene hydrocarbons. The α- and β-forms occur in varying ratios in essential oils.

Purification Methods

Purify it by gas chromatography on an Apiezon column. Also purify it by steam distillation (with 0.5% hydroquinone), then re-distil it through a 50 plate bubble cap column b 72-72.5o/22mm [Pines & Eschinazi J Am Chem Soc 77 6318 1955]. UV: max 263nm ( 3,345) in octane. [Read & Storey J Chem Soc 2770 1930, Beilstein 5 III 341, 5 IV 436.]
