1-Butene
Encyclopedia
1-Butene is an organic chemical compound, linear alpha-olefin
(alkene
), and one of the isomers of butene. The formula is .
and other halogens, nitrogen oxides, boron trifluoride
, hydrohalic acids, and strong oxidizing agents.
. It is distilled to give a very high-purity product. 1-butene is used to manufacture lots of other chemical products, such as linear low-density polyethylene (LLDPE), polypropylene resins, polybutene
, butylene oxide, and methyl ethyl ketone (MEK).

Stability
1-Butene is stable in itself but polymerizes exothermically. It is highly flammable and readily forms explosive mixtures with air. It is, however, incompatible with metal salts, fluorineFluorine
Fluorine is the chemical element with atomic number 9, represented by the symbol F. It is the lightest element of the halogen column of the periodic table and has a single stable isotope, fluorine-19. At standard pressure and temperature, fluorine is a pale yellow gas composed of diatomic...

Boron trifluoride
Boron trifluoride is the chemical compound with the formula BF3. This pungent colourless toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.-Structure and bonding:...

Manufacturing
1-butene is produced either by separation from crude C4 refinery streams or from the reaction of ethyleneEthylene
Ethylene is a gaseous organic compound with the formula . It is the simplest alkene . Because it contains a carbon-carbon double bond, ethylene is classified as an unsaturated hydrocarbon. Ethylene is widely used in industry and is also a plant hormone...

Polybutene
Polybutene and polyisobutylene are liquid oligomers widely used as plasticizers for high-molecular weight polymers, such as polyethylene. They are not to be confused with the high molecular weight polymer polybutene-1.-Properties:...
