Butadiene

.
Butadiene, synthetic chemical compound, used principally in the manufacture of synthetic rubber, nylon, and latex paints.

Most commercial butadiene is made by dehydrogenation of butene or of mixtures of butene and butane; it may also be made from ethanol. Because butadiene has high reactivity, it is useful in synthesis, particularly in polymerization reactions. A large percentage of automobile tires are made from Buna rubber, a copolymer of butadiene and styrene.

Butadiene is a colorless, gaseous hydrocarbon. It is liquefied by cooling to -4.4° C (24.1° F) or by compression to 2.8 atmospheres at 25° C (77° F).
