Igama Lomkhiqizo:1,3-Butadiene

Ifomethi ye-Molecular:C4H6

Inombolo ye-CAS:106-99-0

Isakhiwo samangqamuzana omkhiqizo:

Chemical Properties:

I-1,3-Butadiene i-diene elula ehlanganisiwe.Igesi engenambala enephunga elimnandi elimnandi noma elifana nelikaphethiloli futhi alihambisani ne-phenol, i-chlorine dioxide, ithusi, ne-crotonaldehyde.Igesi inzima kunomoya futhi ingase ihambe phansi;ukuthungela kude kungenzeka.Kuyikhemikhali ebalulekile yezimboni esetshenziswa njenge-monomer ekukhiqizeni irabha yokwenziwa.Iningi le-butadiene li-polymerised ukukhiqiza irabha yokwenziwa.Nakuba i-polybutadiene ngokwayo ithambile kakhulu, icishe ibe uketshezi, izinto ezisetshenziswayo, ama-polymer alungiswe ngezingxube ze-butadiene ne-styrene noma i-acrylonitrile, njenge-ABS, aqinile futhi anwebeka.Irabha ye-styrene–butadiene iyinto esetshenziswa kakhulu ukukhiqiza amathayi ezimoto.Amanani amancane e-butadiene asetshenziselwa ukwenza inayiloni nge-adiponitrile ephakathi, ezinye izinto zerabha zokwenziwa ezifana ne-chloroprene, ne-solvent sulpholane.I-Butadiene isetshenziswa ekukhiqizweni kwezimboni ze-cyclododecatriene ngokusabela kwe-trimerisation.

Isicelo:

I-1,3-Butadiene iwumkhiqizo we-petroleum otholakala ngokuqhekeka kwe-naphtha noma uwoyela okhanyayo noma nge-dehydrogenation ye-buteneor butane.Isetshenziselwa ukukhiqiza i-butadiene-styrene elastomer (yamathayi), i-syntheticrubber, i-thermoplastic elastomers, izinto zokugoqa ukudla, kanye nasekwakheni i-adiponitrile.Iphinde isetshenziselwe ukuhlanganiswa kwezinto eziphilayo yi-Diels-Aldercondensation.

Ama-elastomers okwenziwa (i-styrene-butadiene, i-polybutadiene, i-neoprene, i-nitriles), ama-ABS resins, amakhemikhali aphakathi.
I-1,3-Butadiene ingabhekana nokusabela okuhlangene okunezingxenye ezine nama-aryl Grignard reagents, kanye ne-alkyl fluorides phambi kwe-nickel catalyst ukuze yakhe i-1,6-octadiene carbon compound esikhundleni samaqembu e-alkyl kanye ne-aryl ezindaweni ezingu-3 no-8. .
I-1,3-Butadiene iyi-diene ewusizo yokusabela kwe-Diels Alder.
Ingasetshenziswa ekuhlanganiseni okulandelayo:

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

Irabha yokwenziwa kanye nezinhlaka ze-thermoplastic.

Ama-dimers ahlanjululwe ngokusabela ngama-chlorosilanes.

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