α-PINENE Occupational Safety and Health Administration
Pinene is a collection of unsaturated bicyclic monoterpenes. Two geometric isomers of pinene are found in nature, α-pinene and β-pinene. Both are chiral. As the name suggests, pinenes are found in pines. Specifically, pinene is the major component of the liquid extracts of conifers. Pinenes are also … See more α-Pinene and β-pinene are both produced from geranyl pyrophosphate, via cyclisation of linaloyl pyrophosphate followed by loss of a proton from the carbocation equivalent. Researchers at the Georgia Institute of Technology and the … See more β-Pinene can be converted to α-pinene in the presence of strong bases. Selective oxidation of pinene occurs at the allylic position to give See more • Mann, J.; Davidson, R. S.; Hobbs, J. B.; Banthorpe, D. V.; Harborne, J. B. (1994). Natural Products. Harlow, UK: Addison Wesley Longman … See more Alpha-pinene is the most widely encountered terpenoid in nature and is highly repellent to insects. Alpha-pinene appears in conifers and numerous other … See more Pinenes, especially α, are the primary constituents of turpentine, a nature-derived solvent and fuel. The use of pinene as a biofuel in spark ignition engines has been explored.
