Alpha-pinene is the major constituent of turpentine (about 80%). It exists as a levogyre form in European turpentines, and as a dextrogyre form in turpentines found in North America. Sensitization mainly occurs in painters, polishers and varnishers, and in those in the perfume and ceramics industry.

Chemische Eigenschaften

liquid with a turpentine odour

Chemische Eigenschaften

α-Pinene is the most widespread pinene isomer. (+)-α-Pinene, (1R,5R)-2,6,6-trimethylbicyclo[3.3.1]hept-2-ene, occurs, for example, in oil from Pinus palustris Mill., at a concentration up to 65%; oil from Pinus pinaster Soland and American oil from Pinus caribaea contain 70% and 70–80%, respectively, of the laevorotatory isomer, (?)-α-Pinene, (1S,5S)-2,6,6-trimethylbicyclo[3.3.1]hept-2-ene.
α-Pinene undergoes many reactions, of which the following are used in the fragrance industry: upon hydrogenation, α-pinene is converted to pinane, which has become an important starting material in the industrial processes used in the fragrance and flavor industry. α-Pinene can be isomerized to β-pinene with high selectivity for β-pinene formation. Hydration with simultaneous ring opening yields terpineol and cis-terpin hydrate. Pyrolysis of α-pinene yields a mixture of ocimene and alloocimene.
Pure α-pinene is obtained by distillation of turpentine oils. As a fragrance substance, it is used to improve the odor of industrial products.However, it is farmore important as a starting material in industrial syntheses, for example, terpineols, borneol, and camphor.

Chemische Eigenschaften

α-Pinene has a characteristic odor of pine. It is turpentine-like. The oxidized material has a resin-like odor.


The structure would account for the presence of four optically active and two optically inactive isomers; although only d-, l-, and dl-α-pinene are known, however; presence of one or more isomers has been reported in more than 400 essential oils; in the largest amounts it has been reported found in Achillea millefolium (d-), Artemisia tridentata (d-), Italian rosemary (l-), wild thyme (l-), French lavender (l-), coriander (d-, dl-), cumin (d, dl-), labdanum (l-), neroli (l-), lemon, Litsea cubeba (d-) and ylang-ylang (d-). It is also reported in over 200 natural products including apple, apricot, many citrus juices and peel oils, bilberry, cranberry, lingonberry, blackberry, currants, guava, raspberry, strawberry, orange, lime, grapefruit, mandarin, tangerine oils and juices, various spices, mint essential oils, carrot, celery, cooked potato, bell pepper, tomato, anise, cinnamon, cassia leaf, clove, cumin, ginger, Mentha oils, nutmeg, mace, pepper, parsley, thyme, Swiss and cheddar cheese, cream, fatty fish, fried chicken, beef fat, hop oil, rum, bourbon whiskey, tea, roasted filberts, pecans, oats, soybean, plum, mushroom, sweet and wild marjoram, starfruit, mango, tamarind, cardamom, coriander, gin, rice, litchi, calamus, dill, lovage, caraway seed, buckwheat, laurel, fennel, kiwifruit, myrtle leaf and berry, rosemary, buchu oil, Bourbon vanilla, Spanish and clary sage, nectarine, crayfish, clam, cape gooseberry, anise hyssop, angelica root oil, Roman and German chamomile oil, eucalyptus oil, bullock’s heart and mastic gum leaf and fruit oil.


α-Pinene was used as standard in headspace solid-phase microextraction-gas chromatographic analysis of volatile compounds in virgin olive oils 1 . It was used in the synthesis of cesium-doped heteropolyacid having potential application in biodiesel synthesis.


ChEBI: A pinene that is bicyclo[3.1.1]hept-2-ene substituted by methyl groups at positions 2, 6 and 6 respectively.

Vorbereitung Methode

α-Pinene occurs naturally in a variety of trees and shrubs, including more than 400 essential oils, and air concentrations near pine forests may reach 500–1200 mg/m3. Total U.S. emission of α-pinene from deciduous and coniferous forests amounts to 6.6 million tons annually. An estimated emission rate of α-pinene from natural sources to the atmosphere is 1.84×10 -10 g/cm3/s.


From turpentine, by distillation.

Aroma threshold values

Detection: 2.5 to 62 ppb. Aroma characteristics at 1.0%: terpy citrus and spicy, woody pine and turpentinelike with a slight cooling camphoraceous nutmeglike nuance, a fresh herbal lift and a tropical fruit top note.

Taste threshold values

Taste characteristics at 10 ppm: intense, woody, piney and terpy with camphoraceous and turpentine notes. It has herbal, spicy and slightly tropical mango nuances.

Allgemeine Beschreibung

A clear colorless liquid with a turpentine odor. Flash point 91°F. Less dense than water and insoluble in water. Vapors are heavier than air. Used as a solvent.

Air & Water Reaktionen

Highly flammable. Insoluble in water.

Reaktivität anzeigen

alpha-Pinene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.

Health Hazard

Harmful if swallowed, inhaled or absorbed through skin. High concentrations are extremely destructive to mucous membrane and upper respiratory tract, eyes and skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.


Special Hazards of Combustion Products: Vapor may travel considerable distance to source of ignition and flashback. Container explosion may occur during fire conditions. Forms explosive mixtures in air.

Sensitization occurs mainly in painters, polishers, and varnishers, and in those in the perfume and in the ceramics industry.


A deadly poison by inhalation. Moderately toxic by ingestion. An eye, mucous membrane, and severe human skin irritant. Flammable liquid. A dangerous fire hazard when exposed to heat, flame, or oxidizing materials. To fight fire, use foam, Co2, dry chemical. Explodes on contact with nitrosyl perchlorate.
