용도
Myrcene is the suitable synthetic standard used in the identification of
E-myrcenol (2-methyl-6-methylene-
E-2,7-octadien-1-01) as a major hindgut constituent in Eurasian bark beetle
Ips duplicatus by GC-MS.
제조 방법
From linalool
정의
ChEBI: A monoterpene that is octa-1,6-diene bearing methylene and methyl substituents at positions 3 and 7 respectively.
일반 설명
A yellow oily liquid with a pleasant odor. Flash point below 200°F. Insoluble in water and less dense than water.
공기와 물의 반응
Insoluble in water.
반응 프로필
The unsaturated aliphatic hydrocarbons, such as MYRCENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions. Many of these compounds undergo autoxidation upon exposure to the air to form explosive peroxides. Violent explosions have occurred at low temperatures in ammonia synthesis gas units. These explosions have been traced to the addition products of dienes and oxides of nitrogen, produced from the interaction of nitrogen oxide and oxygen [Bretherick, 1995].
건강위험
May be harmful by inhalation, ingestion or skin absorption.
화재위험
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flashback.
Safety Profile
Low toxicity by
ingestion and skin contact. Experimental
reproductive effects. A moderate skin and
eye irritant. A flammable liquid. When
heated to decomposition it emits acrid
smoke and irritating fumes.
Synthesis
Myrcene occurs naturally in many organisms, but its extraction is uneconomic; it is produced industrially by pyrolysis of b-pinene. The fragmentation of linalool and linalyl acetate and the catalytic dimerization of isoprene have been described as laboratory synthesis methods of myrcene.
