一般描述
(-)-β-Pinene ((1S)-(-)-β-Pinene, (1S,5S)-2(10)-Pinene, (1S,5S)-6,6-Dimethyl-2-methylenebicyclo[3.1.1]heptane) is a terpene. Its conversion to leveorotatory α-pinene by hydrogenation in the presence of palladium catalyst has been proposed. It affords organosulfates on gas-phase ozonolysis in the presence of neutral or acidic sulfate particles during indoor aerosol chamber experiments. Its reaction with ozone has been reported to afford CO2, HCHO, and 6,6-dimethylbicyclo[3.1.1]heptan-2-one.
β-pinene is a volatile monoterepenoid emitted from the Peterson avocado wood. Generation of secondary organic aerosol (SOA) from the gas phase ozonolysis of α- and β-pinene using the Master Chemical Mechanism version 3 (MCM v3) has been reported. β-Pinene is the key ingredient of the essential oil isolated fromCedronella canariensis. It is also the main component of the essential oils of resins ofPinus brutiaandPinus pinea.
应用
(?)-β-Pinene may be used in the preparation of α-terpineol.
β-pinene has been used for the analysis of aroma compounds released from redbay and avocado wood by mass chromatography.
