Alpha-Pinene Ex Turpentine is one of the most abundant terpenoids in nature, which can be obtained from turpentine oil distillation. α - pinene is a colorless liquid with low viscosity. It has special pine wood aroma and turpentine like smell. After hydrogenation, it has rosin like aroma. It is insoluble in water, soluble in ethanol and ether, almost insoluble in propylene glycol and glycerol. α - pinene is an important raw material for the synthesis of borneol, camphor, Perillaldehyde and artificial oil. It can also be used to produce insecticides.

Chemical Properties |
liquid with a turpentine odour |
|
Chemical Properties |
α-Pinene has a characteristic odor of pine. It is turpentine-like. The oxidized material has a resin-like odor. |
|
Uses |
α-Pinene was used as standard in headspace solid-phase microextraction-gas chromatographic analysis of volatile compounds in virgin olive oils 1 . It was used in the synthesis of cesium-doped heteropolyacid having potential application in biodiesel synthesis. |
