2-Methyl-1-pentene Chemical Properties,Uses,Production
Chemical Properties
CLEAR COLOURLESS LIQUID
Physical properties
Clear, colorless flammable liquid with an unpleasant hydrocarbon odor.
Uses
2-Methyl-1-pentene is prepared from 2-Methyl-1-pentene. 2-methyl-1-pentene is used in copolymerization of ethylene catalyzed by nonbridged half-titanocenes. The isomerization of 2-methyl-1-pentene leads to anionic activation of c-h bonds in olefins.
Uses
Organic synthesis, flavors, perfumes,medicines, dyes, oils, resins.
Definition
ChEBI: 2-methyl-1-pentene is an alkene that is pent-1-ene carrying a methyl group at position 2. It has a role as a human metabolite. It is an alkene and a volatile organic compound. It derives from a hydride of a pentane.
General Description
Colorless liquid. Flash point -15°F. Floats on water. Irritating vapor.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
2-Methyl-1-pentene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.
Hazard
Flammable, dangerous fire risk.
Health Hazard
INHALATION: May produce anesthetic effects. EYES: Moderate eye irritation possible.
Fire Hazard
Behavior in Fire: Can react vigorously with oxidizing materials.
Source
California Phase II reformulated gasoline contained 2-methyl-1-pentene at a concentration of 1.25 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 0.23 and 26.6 mg/km, respectively (Schauer et al., 2002).
Environmental Fate
Photolytic. The reported reaction rate constants for the reaction of 2-methyl-1-pentene with OH
radicals and ozone in the atmosphere are 1.05 x 10-17 and 6.26 x 10-11 cm3/moleculesec,
respectively (Atkinson and Carter, 1984; Atkinson, 1985).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
Purification Methods
Water is removed, and formation of peroxides is prevented by several vacuum distillations of 2-methyl-1-pentene from sodium. It is stored with sodium-potassium alloy. [Beilstein 1 IV 841.]
