Verwenden
β-Pinene is also used in flavor compositions, partly as ingredient in artificial Lemon and Nutmeg oils, partly as component of such type flavors. The concentration in the finished product will be about 15 to 150 ppm. alpha-Pinene has a more balsamic taste, while be~a-Pinene, less suitable for flavors, has a dry-woody character.
Vorbereitung Methode
beta-pinene can be produced 1) by isolation from American Turpentine
(minor component).
2) it is also possible to convert alpha-Pinene
into bera-isomer.
Biotechnologische Produktion
Pure alpha-pinene is obtained by distillation of turpentine oils.
Allgemeine Beschreibung
Alpha-pinene appears as 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.
Kontakt-Allergie
Alpha-pinene is the major constituent of turpentine
(about 80%). It exists in levogyre form in European
turpentine and in dextrogyre form in turpentine found
in North-Americans. Sensitization occurs mainly in
painters, polishers, and varnishers, and in those in the
perfume and in the ceramics industry.
