Chemische Eigenschaften
CLEAR COLOURLESS LIQUID
Physikalische Eigenschaften
Clear, colorless flammable liquid with an unpleasant hydrocarbon odor.
Verwenden
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.
Allgemeine Beschreibung
Colorless liquid. Flash point -15°F. Floats on water. Irritating vapor.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivit?t anzeigen
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.
Brandgefahr
Behavior in Fire: Can react vigorously with oxidizing materials.
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 cm
3/molecule?sec,
respectively (Atkinson and Carter, 1984; Atkinson, 1985).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
l?uterung methode
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.]
