Камфен

Химические свойства

Camphene is a colorless to white crystalline solid, Camphor, or turpentine odor. It may be shipped as a liquid. Freezing/Melting point 5 50C.

Вхождение

Reported found in carrot, dill, fennel, marjoram, nutmeg, parsley, pepper, tarragon and thyme.

Использование

Camphene is used in the preparation of fragrances and as a food additive for flavoring.

Подготовка

From pinene by catalytic isomerization or from bornyl chloride by heating with alkali in the presence of abietenesulfonic acid.

Определение

ChEBI: A monoterpene with a bicyclic skeleton that is bicyclo[2.2.1]heptane substituted by geminal methyl groups at position 2 and a methylidene group at position 3. It is a widespread natural product found in many essential oils.

Общее описание

A colorless to white crystalline solid with an insipid camphor-like odor. Dust and crystals are irritants to the eyes, nose and throat. Emits flammable vapors when heated. Emits acrid smoke and irritating fumes at high temperature. Used for the manufacture of synthetic camphor.

Профиль реактивности

Camphene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.

Опасность

Toxic by ingestion.

Угроза здоровью

Inhalation causes irritation of nose and throat. Contact with eyes or skin causes irritation.

Фармаколо?гия

Oral administration of camphene (260 mmols/kg) to rats increased bile flow by 50% 4 hr after administration (M?rsdorf, 1966). Development of atheromatosis of the aorta in rabbits fed 1 g cholesterol/day for 3 months was considerably inhibited by simultaneous administration of a mixture of terpenes including camphene, injected sc in a dose of 1 ml every other day for 6 wk and then given orally in doses of 2 ml/day (Benk?, Macher, Szarvas & Tiboldi, 1961). The effect of 1 g cholesterol/day for 8 wk in the diet of rabbits in increasing the number and volume of mast cells in the aortic adventitia and increasing the total lipid content of the aortic wall was slightly enhanced by the simultaneous addition of 11 g camphene/day (Lesznyak, Benko, Szabo & Muller, 1972). This camphene treatment also decreased the lipid accumulation in the liver, but had no effect on the cholesterol-induced atheromatosis of the aorta (Benko, Szabo, Muller & Lesznyak, 1972).

разработк И противоопухолевых препаратов

This was tested against melanoma cells in a syngeneic model, and there was promisingantitumor activity (Ma et al. 2016).

Профиль безопасности

Mutation data reported. Combustible; yields flammable vapors when heated and can react with oxidizing materials. To fight fire, use water spray, foam, fog, CO2. When heated to decomposition it emits acrid smoke and irritating fumes.

Возможный контакт

Camphene is used to manufacture synthetic camphor; for making moth-proofing and in the cosmetics, perfume, and food flavoring industries.

Несовместимости

Forms explosive mixture with air. Emulsions in xylene may violently decompose on contact with iron or aluminum above 70C. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with reducing agents may cause exothermic reaction, releasing flammable hydrogen gas

Утилизация отходов

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
