C10H16 A bicyclic terpene used as raw material in the synthesis of insecticides such as toxaphene and camphor.

Camphene

 

(3, 3-dimethyl-2-methylenebicyclo-[l, 2, 2]-heptane), a hydrocarbon of the terpene series; colorless crystals with a characteristic camphor odor; melting point, 51°-52°C and boiling point, 160°-161°C.

Camphene is volatile, highly soluble in ether and benzene, less soluble in alcohol, and insoluble in water. It occurs in small quantities in turpentines and in essential pine oils, from which it may be isolated by distillation and freezing out. It is also found in lavender and fennel oils as well as in other essential oils. Camphene is produced industrially by the catalytic isomerization of pinene. Widely used in industry, it is an intermediate product in the synthesis of camphor. Chlorination of camphene yields very effective insecticides.
