camphene

cam·phene

C0055000 (kăm′fēn′)n. A colorless crystalline terpene, C₁₀H₁₆, occurring naturally in numerous essential oils and used in the manufacture of synthetic camphor and insecticides.

[camph(or) + -ene.]

camphene

(ˈkæmfiːn) n (Elements & Compounds) a colourless crystalline insoluble optically active terpene derived from pinene and present in many essential oils. Formula: C10H16[C19: from camph(or) + -ene]

cam•phene

(ˈkæm fin, kæmˈfin)

n. a colorless, crystalline, water-insoluble substance, C₁₀H₁₆, used in the manufacture of synthetic camphor. [1835–45; < New Latin camph(ora) camphor + -ene]

Camphine

There seem to be some differing opinions on the meaning of this word. According to recent dictionaries, it is a mixture of turpentine and alcohol used in the mid-1800s in lamps. Because of volatility, the use of the mixture was soon abandoned. Thwing, in his book Flickering Flames, says the word is camphene, that it referred to turpentine only, and that the alcohol-turpentine mixture was called “burning fluid.” Note that a Handbook of Chemistry lists camphene as the specific compound C10H16.

Camphene

camphene

[′kam‚fēn] (organic chemistry) 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.
