nature : a C10H16 a terpenes. Following two isomers. (1) α - pinene (α - pinene) Turpentine the main ingredients. A colorless and transparent liquid. Pine terpene with unique odor. Density 0.8582. The boiling point of 156 ° C. Refractive index of 1.4658 (20 ° C). A L-, D-and racemic equation. Do not dissolve in water, soluble in alcohol, ether and other organic solvents and soluble in rosin. For varnish, wax, and the solvent system Camphene, terpene hydrate, terpineol, pine oil, terpinen ether, borneol, synthetic camphor, synthetic resins and other raw material. (2) β - pinene (β - pinene) Turpentine the major components. A colorless and transparent liquid. Terpene is the unique pine aroma. Density 0.8654. The boiling point 164 ° C. Refractive index of 1.4739 (20 ° C). Α - pinene together can be used as a solvent. After the separation used in manufacturing synthetic resins, such as alcohol Cinnamomum camphora raw materials. Α-and β - pinene from turpentine under reduced pressure distillation and obtained.
