The formula is CH3CH2CH=CH2. It is a highly flammable, easily condensed gas. Reactions1-Butene is stable in itself but polymerizes readily to polybutene. 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.[3] Manufacturing1-Butene is produced by separation from crude C4 refinery streams and by ethylene dimerization. The former affords a mixture of 1-and 2-butenes, while the latter affords only the terminal alkene.[4] It is distilled to give a very high-purity product. An estimated 12 billion kilograms were produced in 2011.[5] See also
