Uses
Uses in perfumery :
Beta-Pinene is used in terpenic, woody and coniferous accords, to provide a fresh, lemony, pine needle facet.
Year of discovery :
Data not available.
Natural availability :
Beta-Pinene is present in citrus raw materials (Lemon EO, Bergamot EO, Sweet Orange EO), in spices (Black Pepper EO, Elemi EO, Nutmeg EO), in Galbanum EO and in Turpentine EO. This molecule can be extracted by fractional distillation of all these essential oils.
Isomerism :
Beta-Pinene has two enantiomers, laevorotatory and dextrorotatory, both used in perfumery. Both isomers have a similar smell, although the dextrorotatory isomer is sweeter. Alpha-Pinene is more camphorated and less woody than beta-Pinene.
Synthesis precursor :
Beta-Pinene is a precursor for the synthesis of Myrcene by pyrolysis. Moreover, an addition of formaldehyde on this compound forms nopol. Nopyl acetate is used in perfumery.
Synthesis route :
The synthesis of Beta-Pinene is less common than its extraction from Turpentine EO. This extraction is done by a fractional distillation.
