  • Benchmark different countries by the historic and forecast growth of demand, production and end-use of butadiene. (environmental-expert.com)
  • While not competitive with steam cracking for producing large volumes of butadiene, lower capital costs make production from ethanol a viable option for smaller-capacity plants. (wikipedia.org)
  • As of 2017 there is no industrial production of butadiene from ethanol. (wikipedia.org)
  • The butadiene production method, which was based on aldol condensation of acetaldehyde (1905), was also implemented on industrial scale in Germany in 1936. (wikipedia.org)

  • oxidative
  • This compound is converted to a Grignard reagent by action of magnesium metal which is then reacted with copper(I) chloride to an organocopper intermediate which is in turn dimerized using copper(II) chloride in an oxidative coupling reaction to give the butadiene dimer called dendralene. (wikipedia.org)
  • sodium
  • The material was initially marketed with the brand name Buna S. Its name derives Bu for butadiene and Na for sodium (natrium in several languages including Latin, German, and Dutch), and S for styrene. (wikipedia.org)
