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.

Dodecane, naphthalene, p-xylene, 1,2,4-trichlorobenzene, kerosene and camphene have been used to dissolve UHMWPE [7, 11-17], These UHMWPE solutions exhibit a thermo-reversible gelation behavior due to crystallization of polyethylene upon cooling; however, fibers obtained by gel spinning with the aforementioned solutions exhibit tensile strength usually less than 3 GPa.
