Na Waiwai Kemika:

ʻO ka 1,3-Butadiene kahi diene conjugated maʻalahi.He kinoea waihoʻoluʻu me ka ʻala ʻala a i ʻole ka ʻala like me ka ʻaila a kūpono ʻole me phenol, chlorine dioxide, keleawe, a me crotonaldehyde.ʻOi aku ke kaumaha o ke kinoea ma mua o ka ea a hiki ke hele ma ka honua;hiki ke puhi mamao.He mea ʻenehana koʻikoʻi ia i hoʻohana ʻia ma ke ʻano he monomer i ka hana ʻana i ka lāʻau synthetic.ʻO ka hapa nui o ka butadiene i polymerised e hana i ka lāʻau synthetic.ʻOiai ʻo ka polybutadiene ponoʻī he mea palupalu loa, kokoke i ka wai, nā polymers i hoʻomākaukau ʻia mai nā hui ʻana o ka butadiene me ka styrene a i ʻole acrylonitrile, e like me ABS, he paʻakikī a elastic.ʻO Styrene-butadiene rubber ka mea i hoʻohana pinepine ʻia no ka hana ʻana i nā huila kaʻa.Hoʻohana ʻia ka nui liʻiliʻi o ka butadiene no ka hana ʻana i ka nylon ma o ka adiponitrile waena, nā mea hoʻoheheʻe synthetic ʻē aʻe e like me ka chloroprene, a me ka sulpholane solvent.Hoʻohana ʻia ʻo Butadiene i ka hana ʻenehana o cyclododecatriene ma o ka hopena trimerization.

Noi:

ʻO 1,3-Butadiene kahi huahana aila i loaʻa ma ka hoʻoheheʻe ʻana o ka naphtha a i ʻole ka aila kukui a i ʻole ka dehydrogenation o ka butene a me ka butane.Hoʻohana ʻia ia no ka hana ʻana i ka butadiene-styrene elastomer (no nā kaʻa), syntheticrubber, thermoplastic elastomers, mea ʻai meaʻai, a i ka hana ʻana o adiponitrile.Hoʻohana ʻia ia no ka synthesis o nā organik e Diels-Aldercondensation.

Synthetic elastomers (styrene-butadiene, polybutadiene, neoprene, nitriles), ABS resins, kemika waena.
Hiki i ka 1,3-Butadiene ke hana i ka hoʻohui hui ʻehā me nā reagents aryl Grignard, a me nā fluoride alkyl i mua o ka nickel catalyst e hana i ka hui kalapona 1,6-octadiene i pani ʻia me nā hui alkyl a me nā aryl ma nā kūlana 3 a me 8. .
ʻO 1,3-Butadiene kahi diene pono no ka hopena Diels Alder.
Hiki ke hoʻohana ʻia i ka synthesis o kēia mau mea:

1-Silyl-substituted 1,3-butadienes, e [RuHCl(CO)(PCy3)2]-catalyzed silylative hoopili ana o terminal (E)-1,3-dienes me vinylsilanes.

ʻO ka lāʻau synthetic a me nā resins thermoplastic.

ʻO nā dimer disilylate ma ka hana ʻana me nā chlorosilanes.

Octa-2,7-dien-1-ol ma o ka palladium catalyzed-hydrodimerization.
