Chemistry:1,2-Butadiene
From HandWiki
1,2-Butadiene is the organic compound with the formula CH2=C=CHCH3. It is an isomer of 1,3-butadiene, a common monomer used to make synthetic rubber. It is a colorless flammable gas, one of the simplest substituted allenes.[1]
Production
The C4-fraction obtained by cracking and separated by distillation consists of many compounds, predominantly (75%) 1,3-butadiene, isobutene, 1-butene. 1,2-Butadiene comprises less than 1% or this mixture.[2] It is partially purified by extraction with N-methylpyrrolidone. US product is 5,000 -25,000 tons.[1]
