Butadiene

1,3-Butadiene is the <a href="/facts/Organic_compound/gqCNaN45">organic compound</a> with the formula CH2=CH-CH=CH2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to <a href="/facts/Synthetic_rubber/58Fq4XYx">synthetic rubber</a>. The molecule can be viewed as the union of two <a href="/facts/Vinyl_group/SyXSgVnw">vinyl groups</a>. It is the simplest <a href="/facts/Conjugated_diene/F5NxrLPW">conjugated diene</a>.
Although butadiene <a href="/facts/Chemical_degradation/4X3oxvhb">breaks down</a> quickly in the atmosphere, it is nevertheless found in ambient air in urban and suburban areas as a consequence of its constant <a href="/facts/Exhaust_gas/kLpq1eUX">emission</a> from <a href="/facts/Motor_vehicle/AaXamA0w">motor vehicles</a>.
The name butadiene can also refer to the <a href="/facts/Isomer/PXlvDVdg">isomer</a>, <a href="/facts/1%2c2-butadiene/7PfwBDs0">1,2-butadiene</a>, which is a <a href="/facts/Diene/F5NxrLPW">cumulated diene</a> with structure H2C=C=CH−CH3. This <a href="/facts/Allene/54hMEu5N">allene</a> has no industrial significance.
