Njirimara kemịkalụ:

1,3-Butadiene bụ nri ejikọtara ọnụ dị mfe. Ọ bụ gas na-enweghị agba nke nwere isi ísì ụtọ dị nro ma ọ bụ mmanụ ụgbọala na-ekwekọghị na phenol, chlorine dioxide, ọla kọpa, na crotonaldehyde. Gas dị arọ karịa ikuku ma nwee ike ịgafe n'ala; mgbanye dị anya ga-ekwe omume. Ọ bụ kemịkalụ ụlọ ọrụ dị mkpa eji dị ka monomer na-emepụta roba sịntetik. Ọtụtụ butadiene bụ polymerised iji mepụta rọba sịntetik. Ọ bụ ezie na polybutadiene n'onwe ya bụ ihe dị nro, ihe fọrọ nke nta ka ọ bụrụ mmiri mmiri, ihe onwunwe, polymers nke a kwadebere site na ngwakọta nke butadiene na styrene ma ọ bụ acrylonitrile, dị ka ABS, dị ike ma na-agbanwe. Styrene–butadiene rọba bụ ihe a na-ejikarị eme taya ụgbọ ala. A na-eji obere butadiene eme naịlọn site na adiponitrile etiti, ihe rọba sịntetị ndị ọzọ dị ka chloroprene, na ihe mgbaze sulpholane. A na-eji Butadiene na mmepụta mmepụta nke cyclododecatriene site na mmeghachi omume nke trimerisation.

Ngwa:

1,3-Butadiene bụ ngwaahịa mmanụ ala enwetara site na mgbawa nke naphtha ma ọ bụ mmanụ ọkụ ma ọ bụ site na mmịpụta nke buteneor butane. A na-eji ya na-emepụta butadiene-styrene elastomer (maka taya), syntheticrubber, thermoplastic elastomer, ihe nkpuchi nri, na mmepụta nke adiponitrile. A na-ejikwa ya maka njikọ nke organics site na Diels-Aldercondensation.

Sịntetị elastomers (styrene-butadiene, polybutadiene, neoprene, nitriles), ABS resins, chemical intermediate.
1,3-Butadiene nwere ike nweta mmeghachi omume njikọta akụkụ anọ na aryl Grignard reagents, na alkyl fluorides na ọnụnọ nke nickel catalyst iji mepụta 1,6-octadiene carbon compound dochie ya na alkyl na aryl otu na 3- na 8-ọnọdụ. .
1,3-Butadiene bụ nri bara uru maka mmeghachi omume Diels Alder.
Enwere ike iji ya na njikọ nke ndị a:

1-Silyl-dochiri 1,3-butadienes, site [RuHCl (CO) (PCy3) 2] -catalyzed silylative njikọ nke ọnụ (E) -1,3-dienes na vinylsilanes.

roba sịntetik na thermoplastic resins.

Dimers nwere nkụda mmụọ site na iji chlorosilanes meghachi omume.

Octa-2,7-dien-1-ol site na palladium catalyzed-hydrodimerization.
