Product Name:1,3-Butadiene

Molecular format:C4H6

CAS nhamba:106-99-0

Chigadzirwa chemolecular chimiro:

Chemical Properties:

1,3-Butadiene iri nyore conjugated diene. Igasi risina ruvara rine kunhuhwirira kwakapfava kana kuti peturu-rakafanana uye harienderane nephenol, chlorine dioxide, mhangura, uye crotonaldehyde. Iyo gasi inorema kupfuura mweya uye inogona kufamba pasi; kubatidza kure kunogoneka. Ikemikari yakakosha yeindasitiri inoshandiswa semonomer mukugadzirwa kwerabha yekugadzira. Most butadiene is polymerised kugadzira synthetic rubber. Nepo polybutadiene pachayo iri yakapfava kwazvo, inenge mvura, zvinhu, mapolima akagadzirwa kubva mumisanganiswa yebutadiene ine styrene kana acrylonitrile, senge ABS, zvese zvakaoma uye elastic. Styrene-butadiene rabha ndicho chinhu chinonyanya kushandiswa kugadzira matayi emotokari. Zvidiki zvidiki zvebutadiene zvinoshandiswa kugadzira nylon kuburikidza nepakati adiponitrile, zvimwe zvekugadzira rabha zvinhu zvakaita se chloroprene, uye solvent sulpholane. Butadiene inoshandiswa mukugadzirwa kwemaindasitiri kwe cyclododecatriene kuburikidza ne trimerisation reaction.

Application:

1,3-Butadiene chigadzirwa che petroleum chinowanikwa necatalytic cracking ye naphtha orlight oil kana ne dehydrogenation ye buteneor butane. Inoshandiswa kugadzira butadiene-styrene elastomer (yematayi), syntheticrubber, thermoplastic elastomers, chikafu chekuputira, uye mukugadzira adiponitrile. Inoshandiswawo kugadzira organics neDiels-Aldercondensation.

Synthetic elastomers (styrene-butadiene, polybutadiene, neoprene, nitriles), ABS resins, kemikari yepakati.
1,3-Butadiene inogona kupinda mana-component coupling reaction nearyl Grignard reagents, uye alkyl fluorides pamberi penickel catalyst kuumba 1,6-octadiene carbon compound inotsiviwa nealkyl uye aryl mapoka pa3- uye 8-zvinzvimbo. .
1,3-Butadiene ndiyo diene inobatsira yeDiels Alder reaction.
Inogona kushandiswa mukugadzirisa kwezvinotevera:

1-Silyl-inotsiva 1,3-butadienes, ne [RuHCl(CO) (PCy3)2] -catalyzed silylative coupling yekuguma (E) -1,3-dienes nevinylsilanes.

Synthetic rubber uye thermoplastic resins.

Disilylated dimers nekuita nema chlorosilanes.

Octa-2,7-dien-1-ol kuburikidza ne palladium catalyzed-hydrodimerization.
