| Hazard Information | Back Directory | [General Description]
A yellow oily liquid with a pleasant odor. Flash point below 200°F. Insoluble in water and less dense than water. | [Reactivity Profile]
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]. | [Air & Water Reactions]
Insoluble in water. | [Health Hazard]
May be harmful by inhalation, ingestion or skin absorption. | [Fire Hazard]
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flashback. | [Description]

Odor at 1% | [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. | [storage]
