Lebitso la Sehlahiswa:1,3-Butadiene

Sebopeho sa molek'hule:C4H6

Nomoro ea CAS:106-99-0

Sehlahisoa sebopeho sa molek'hule:

Lintho tsa Lik'hemik'hale:

1,3-Butadiene ke diene e bonolo ea conjugated. Ke khase e se nang 'mala e nkhang hamonate kapa ea monko o kang oa peterole 'me ha e lumellane le phenol, chlorine dioxide, koporo le crotonaldehyde. Khase e boima ho feta moea 'me e ka tsamaea fatše; ho bulela hole hoa khoneha. Ke lik'hemik'hale tsa bohlokoa tsa indasteri tse sebelisoang e le monoma ha ho etsoa rabara ea maiketsetso. Bongata ba butadiene bo entsoe ka polymerised ho hlahisa rabara ea maiketsetso. Le hoja polybutadiene ka boeona e le ntho e bonolo haholo, hoo e batlang e le metsi, li-polymers tse lokiselitsoeng ho tloha motsoako oa butadiene le styrene kapa acrylonitrile, tse kang ABS, li thata ebile li le elastic. Rabara ea styrene–butadiene ke thepa e sebelisoang haholo ho etsa lithaere tsa koloi. Bongata bo bonyenyane ba butadiene bo sebelisetsoa ho etsa nylon ka adiponitrile e bohareng, lisebelisoa tse ling tsa rabara tse kang chloroprene, le solvent sulpholane. Butadiene e sebelisoa tlhahiso ea indasteri ea cyclododecatriene ka karabelo ea trimerisation.

Kopo:

1,3-Butadiene ke sehlahisoa sa petroleum se fumanoeng ka ho phatloha ho hoholo ha oli ea naphtha orlight kapa ka dehydrogenation ea buteneor butane. E sebelisetsoa ho hlahisa butadiene-styrene elastomer (bakeng sa lithaere), syntheticrubber, thermoplastic elastomers, lisebelisoa tsa ho koahela lijo, le ho etsa adiponitrile. E boetse e sebelisetsoa ho kopanya lintho tse phelang le Diels-Aldercondensation.

Li-elastomer tsa maiketsetso (styrene-butadiene, polybutadiene, neoprene, nitriles), li-resin tsa ABS, lik'hemik'hale tse mahareng.
1,3-Butadiene e ka ba le motsoako oa likarolo tse 'nè le li-reagents tsa aryl Grignard, le alkyl fluorides ka pel'a nickel catalyst ho theha motsoako oa carbon oa 1,6-octadiene o nkeloang sebaka ke lihlopha tsa alkyl le aryl sebakeng sa 3- le 8-maemo. .
1,3-Butadiene ke diene e sebetsang bakeng sa karabelo ea Diels Alder.
E ka sebelisoa ho kopanya lintho tse latelang:

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

Rabara ea maiketsetso le li-resin tsa thermoplastic.

Li-dimers tse nang le disilylated ka ho sebetsana le li-chlorosilanes.

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