1,3-butadiene usage and synthesis

chemical properties	colourless gas, or pressurised liquid (odour tlv 1.6 ppm)
definition	chebi: a butadiene with unsaturation at positions 1 and 3.
general description	butadiene, inhibited is a colorless gas with an aromatic odor. 1,3-butadiene is shipped as a liquefied gas under its vapor pressure. contact with the liquid can cause frostbite. 1,3-butadiene is easily ignited. its vapors are heavier than air and a flame can flash back to the source of leak very easily. 1,3-butadiene can asphyxiate by the displacement of air. 1,3-butadiene must be shipped inhibited as butadiene is liable to polymerization. if polymerization occurs in the container, 1,3-butadiene may violently rupture. under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. 1,3-butadiene is used to make synthetic rubber and plastics, and to make other chemicals.
air & water reactions	highly flammable. in contact with air, butadiene may form violently explosive peroxides, which can be exploded by mild heat or shock. solid butadiene absorbs enough oxygen at sub atmospheric pressures to make 1,3-butadiene explode violently when heated just above its melting point [ind. eng. chem. 51:733 1959].
reactivity profile	a colorless gas, 1,3-butadiene can react with oxidizing reagents. upon long exposure to air 1,3-butadiene forms explosive peroxides. they are sensitive to heat or shock; sudden polymerization may occur [scott, d. a., chem. eng. news, 1940, 18, p.404]. butadiene polyperoxides are insoluble in liquefied butadiene (m. p. -113° c, b. p. -2.6° c) and progressively separate leading to local concentration build up. self-heating from a spontaneous decomposition will lead to explosion [hendry, d. g. et al., ind. eng. chem., 1968, 7, p. 136, 1145]. explodes on contact with aluminum tetrahydroborate, potentially explosive reaction with chlorine dioxide (peroxide) and crotonaldehyde (above 180° c). reaction with sodium nitrite forms a spontaneously flammable product [sax, 9th ed., 1996, p. 539].
health hazard	slight anesthetic effect at high concentrations; causes ``frostbite'' from skin contact; slight irritation to eyes and nose at high concentrations.
fire hazard	behavior in fire: vapors heavier than air and may travel a considerable distance to a source of ignition and flashback. containers may explode in a fire due to polymerization.
