Dobijanje i hemija
Način dobijanja
The pinenes in turpentine are separated and purified by distillation. Nowadays, turpentine is rarely the product of distillation of pine resin, but is a byproduct of pulping. The kraft process gives a pinene-rich turpentine, whereas the sulfite process gives one rich in cymene. Crude sulfate turpentine is a by-product of the kraft process. Refiners of crude sulfate turpentine primarily separate the purified turpentine into its main components, alpha- and beta-pinene.

U parfemima
Beta-pinene is used in the production of other aroma compounds. When nopol is acetylated, the result is nopyl acetate, which is used as fragrance material. Myrcene, which is made from beta-pinene, is rarely used directly in the perfumery industry. Instead, it is a precursor to many fragrances, such as menthol, citral, citronellol, citronellal, geraniol, nerol and linalool. 2-Pinanol, derived from pinene, gives linalool upon pyrolysis.
