1-Butene

Formula: C4H8

1-Butene is a colorless, flammable, liquefied gas with a slight aromatic odor. It is shipped as a liquid under its own vapor pressure.

It is part of the alkene group of hydrocarbons. They serve as intermediates in the preparation of a variety of organic compounds. Its main application is as a comonomer in the production of certain kinds of polyethylene, such as linear low-density polyethylene (LLDPE). It has also been used as a precursor to polypropylene resins, butylene oxide, and butanone.

1-Butene is also used as feedstock for the production of 1,2-butylene oxide, methylethylketone (MEK), maleic anhydride and n-butyl derivatives. Butene-1 has good solvent properties.
