Igama lemveliso:1,3-Butadiene

Imo yemolekyuli:C4H6

Inombolo yeCAS:106-99-0

Imveliso yesakhiwo semolekyuli:

Iipropati zeMichiza:

I-1,3-Butadiene yi-diene edibeneyo elula. Yigesi engenambala enevumba elimnandi okanye elifana nepetroli kwaye ayihambelani nephenol, ichlorine dioxide, ubhedu, kunye necrotonaldehyde. Irhasi inzima kunomoya kwaye inokuhamba emhlabeni; ukucima okude kunokwenzeka. Yikhemikhali ebalulekileyo yoshishino esetyenziswa njenge-monomer kwimveliso yerabha yokwenziwa. Uninzi lwe-butadiene i-polymerised ukuvelisa irabha yokwenziwa. Ngelixa i-polybutadiene ngokwayo ithambile kakhulu, iphantse ibe lulwelo, imathiriyeli, iipholima ezilungiselelwe ukusuka kwimixube ye-butadiene ene-styrene okanye i-acrylonitrile, efana ne-ABS, zombini ziqinile kwaye zi-elastic. Irabha ye-Styrene–butadiene yeyona nto isetyenziswa kakhulu ukuvelisa amatayara emoto. Amanani amancinci e-butadiene asetyenziselwa ukwenza inayiloni nge-adiponitrile ephakathi, ezinye izinto zerabha zokwenziwa ezifana ne-chloroprene, kunye ne-solvent sulpholane. I-Butadiene isetyenziswa kwimveliso yemizi-mveliso ye-cyclododecatriene ngokusabela kwe-trimerisation.

Isicelo:

I-1,3-Butadiene yimveliso yepetroleum efunyenwe ngokuqhekeka kwe-catalytic ye-naphtha okanye ioli ekhanyayo okanye i-dehydrogenation ye-buteneor butane. Isetyenziselwa ukuvelisa i-butadiene-styrene elastomer (yamathaya), i-syntheticrubber, i-thermoplastic elastomers, izinto zokuvala ukutya, kunye nokwenziwa kwe-adiponitrile. Ikwasetyenziselwa ukuhlanganiswa kwezinto eziphilayo yiDiels-Aldercondensation.

I-elastomers zokwenziwa (i-styrene-butadiene, i-polybutadiene, i-neoprene, i-nitriles), i-resin ze-ABS, i-chemical intermediate.
I-1,3-Butadiene inokuthi iqhube i-four-component reaction reaction kunye ne-aryl Grignard reagents, kunye ne-alkyl fluorides phambi kwe-nickel catalyst ukwenza i-1,6-octadiene carbon compound endaweni ye-alkyl kunye namaqela e-aryl kwi-3- kunye ne-8-izikhundla. .
I-1,3-Butadiene i-diene eluncedo kwi-Diels Alder reaction.
Inokusetyenziswa ekudibaneni koku kulandelayo:

I-1-Silyl-ifakwe endaweni ye-1,3-butadienes, yi- [RuHCl (CO) (PCy3) 2] -catalyzed silylative coupling of terminal (E) -1,3-dienes kunye ne-vinylsilanes.

Irabha yokwenziwa kunye ne-thermoplastic resins.

Ii-dimers ezichithwayo ngokusabela ngeklorosilanes.

I-Octa-2,7-dien-1-ol nge-palladium catalyzed-hydrodimerization.
