1,3-butadiene

Product name 1,3-butadiene
GOST no data
CAS 106-99-0

1,3-Butadiene is a colorless gas with unpleasant odor. It is readily soluble in benzene, ether, chloroform, CCl4; almost insoluble in methanol and ethanol. Butadiene is a simple conjugated diene. It can be easily polymerized or copolymerized with styrene, nitriles or esters of acrylic or methacrylic acid, vinyl- and methylvinylpyridines, isobutylene, isoprene and other monomers.

Production.

  • butadiene is produced as a byproduct of the steam cracking process used to produce ethylene and other olefins. When mixed with steam and briefly heated to very high temperatures (often over 900 °C), aliphatic hydrocarbons give up hydrogen to produce a complex mixture of unsaturated hydrocarbons, including butadiene. It is typically isolated from the other four-carbon hydrocarbons produced in steam cracking by extraction into a polar aprotic solvent such as acetonitrile or dimethylformamide, from which it is then stripped by distillation.
  • 1,3-butadiene can also be produced by the catalytic dehydrogenation of normal butane or n-butenes.

    Uses.

  • Butadiene is used primarily as a monomer in the production of a wide range of polymers and co-polymers. The largest single use for butadiene is in the production of styrene-butadiene rubber (SBR) which, in turn, is principally used in the manufacture of tyres. Other butadiene co-polymerization products should be mentioned too: that is acrylonitrile-butadiene rubber, styrene-butadiene latex, ABS resins.
  • butadiene is an intermediate product in preparation of adiponitrile, chloroprene, butylene glycol, cyclododecatriene, 1,4-hexadiene;
