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.

1999), deduced that early distillate fractions contained most of the alpha-thujene, alpha-pinene, camphene, betapinene and 1,8-cineole (eucalyptol), while later fractions contained most of the camphor and bornyl acetate.
In contrast to DDT, which is easy to prepare with high purity, insecticides obtained by chlorination of benzene (hexachlorocyclohexane) and camphene (toxaphene) are used as isomer mixtures with 12% active [gammar]-hexachloro-cyclohexane (lindane) (Brooks 1977) and 0.
Consequently, we used 6 substances in our experiments: essential oils of Norway spruce and common juniper (because we assumed that these odours might be deterrent) and the monoterpenes limonene, camphene, borneol, and eucalyptol.

In Geneva, the negotiators were clearly in favour of phasing out the production and use of three POPs: aldrin (a chlorinated hydrocarbon used as an insecticide), endrin (chlorine-containing organic compound used as an insecticide) and toxaphene (mixture of organic compounds made by chlorination of camphene and used as an insecticide).
