说明

(-)-β-蒎烯 ((1S)-(-)-β-蒎烯, (1S,5S)-2(10)-蒎烯, (1S,5S)-6,6-Dimethyl-2-methylenebicyclo[3.1 .1]庚烷）是一种萜烯。已经提出在钯催化剂存在下通过氢化将其转化为左旋α-蒎烯。在室内气溶胶室实验中，在存在中性或酸性硫酸盐颗粒的情况下，它通过气相臭氧分解提供有机硫酸盐。据报道，它与臭氧的反应会产生 CO2、HCHO 和 6,6-二甲基双环[3.1.1]庚烷-2-酮。

β-蒎烯是一种从彼得森鳄梨木中散发出来的挥发性单萜类化合物。据报道，使用主化学机制版本 3 (MCM v3) 从 α- 和 β- 蒎烯的气相臭氧分解产生二次有机气溶胶 (SOA)。 β-蒎烯是从 Cedronella canariensis 中分离出来的精油的关键成分。它也是黑松和松树树脂精油的主要成分。

(-)-β-蒎烯可用于制备α-松油醇。
β-蒎烯已用于通过质谱分析从红月桂和鳄梨木释放的香气化合物。

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 from Cedronella canariensis. It is also the main component of the essential oils of resins of Pinus brutia and Pinus 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.
