Chemical Properties:

1,3-Butadiene ndi diene yosavuta conjugated.Ndi gasi wopanda mtundu wokhala ndi fungo lonunkhira bwino kapena lopanda mafuta ndipo sugwirizana ndi phenol, chlorine dioxide, mkuwa, ndi crotonaldehyde.Mpweyawu ndi wolemera kuposa mpweya ndipo umatha kuyenda pansi;kuyatsa kutali ndi kotheka.Ndi mankhwala ofunikira a mafakitale omwe amagwiritsidwa ntchito ngati monomer popanga mphira wopangira.Ambiri a butadiene amapangidwa polima kuti apange mphira wopangira.Ngakhale polybutadiene palokha ndi yofewa kwambiri, pafupifupi madzi, zinthu, ma polima opangidwa kuchokera ku zosakaniza za butadiene ndi styrene kapena acrylonitrile, monga ABS, onse ndi olimba komanso zotanuka.Rabara ya styrene-butadiene ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga matayala apagalimoto.Zochepa za butadiene zimagwiritsidwa ntchito popanga nayiloni kudzera pa adiponitrile yapakatikati, zida zina zopangira mphira monga chloroprene, ndi solvent sulpholane.Butadiene imagwiritsidwa ntchito popanga mafakitale a cyclododecatriene kudzera munjira ya trimerisation.

Ntchito:

1,3-Butadiene ndi mankhwala opangidwa ndi petroleum omwe amapezeka ndi kusweka kwamafuta a naphtha orlight kapena dehydrogenation wa buteneor butane.Amagwiritsidwa ntchito popanga butadiene-styrene elastomer (ya matayala), syntheticrubber, thermoplastic elastomers, foodwrapping materials, ndi kupanga adiponitrile.Amagwiritsidwanso ntchito popanga organics ndi Diels-Aldercondensation.

Synthetic elastomers (styrene-butadiene, polybutadiene, neoprene, nitriles), utomoni wa ABS, mankhwala apakatikati.
1,3-Butadiene ikhoza kugwirizanitsa zigawo zinayi zogwirizanitsa ndi aryl Grignard reagents, ndi alkyl fluorides pamaso pa nickel catalyst kupanga 1,6-octadiene carbon pawiri m'malo ndi alkyl ndi aryl magulu pa 3- ndi 8-malo. .
1,3-Butadiene ndi diene yothandiza pakuchita kwa Diels Alder.
Itha kugwiritsidwa ntchito pophatikizira zotsatirazi:

1-Silyl-substituted 1,3-butadienes, ndi [RuHCl(CO) (PCy3)2] -catalyzed silylative coupling of terminal (E) -1,3-dienes ndi vinylsilanes.

Zopangira mphira ndi thermoplastic resins.

Dimers osungunuka pochita ndi ma chlorosilanes.

Octa-2,7-dien-1-ol kudzera pa palladium catalyzed-hydrodimerization.
