10. Uses
1. α-Pinene is an anti-inflammatory
2. α-pinene is used in the manufacture of camphor,
solvents, plastics, and insecticides.
3. Turpentine:
It is used as a solvent.
It is used as a source of materials for organic
synthesis.
It is used for thinning oil-based paints, for
producing varnishes, and as a raw material for
the chemical industry.

12. Isomers Of Pinene
There are two structural isomers of pinene
found in nature:
α-pinene
β-pinene
Turpentine contains 58%-65% a-pinene and
about 30% of ß-pinene.

14. SYNTHESIS OF PINENE
11/24/2017 14RABIA AZIZ

15. Synthesis of Pinene
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.
