Igoa Oloa：1,3-Butadiene

fa'asologa mole:C4H6

Numera CAS:106-99-0

Fua mole mole oloa：

Meatotino tau vailaau:

1,3-Butadiene o se diene fa'atasi faigofie. O se kasa e leai ni lanu ma se manogi manogi po o le penisini pei o le manogi ma e le fetaui ma le phenol, chlorine dioxide, copper, ma le crotonaldehyde. E sili atu le mamafa o le kesi nai lo le ea ma e mafai ona fealuai i luga o le eleele; e mafai ona fa'amumu mamao. O se vaila'au fa'apisinisi taua e fa'aaogaina e fai ma monomer i le gaosiga o pa'u fa'apipi'i. O le tele o le butadiene e polymerised e maua ai le pa'u gaosia. E ui o le polybutadiene lava ia ose mea vaivai, toetoe lava a sua, polymers saunia mai faʻafefiloi o le butadiene ma le styrene poʻo le acrylonitrile, pei ole ABS, e maʻaʻa ma faʻamalosi. Styrene-butadiene pa'u o le mea e masani ona fa'aogaina mo le gaosiga o pa'u ta'avale. E la'ititi la'ititi o le butadiene e fa'aaogaina e fai ai le nailoni e ala i le adiponitrile intermediate, isi mea pa'u gaosia e pei ole chloroprene, ma le solvent sulpholane. Butadiene o lo'o fa'aaogaina i le gaosiga o fale gaosi oloa o le cyclododecatriene e ala i se fa'afouga trimerization.

Talosaga:

1,3-Butadiene o se oloa suau'u maua e catalytic ta'e o le naphtha po o le suauu moli po o le dehydrogenation o butene po'o butene. E fa'aaogaina e gaosia ai le butadiene-styrene elastomer (mo pa'u), syntheticrubber, thermoplastic elastomers, mea e afifi ai mea'ai, ma i le gaosiga ole adiponitrile. E faʻaaogaina foʻi mo le tuʻufaʻatasia o meaola e le Diels-Aldercondensation.

Elastomers fa'asusu (styrene-butadiene, polybutadiene, neoprene, nitriles), ABS resins, vailaʻau vavalo.
1,3-Butadiene e mafai ona oʻo i se faʻalavelave faʻafesoʻotaʻi faʻatasi ma aril Grignard reagents, ma alkyl fluoride i le i ai o le nickel catalyst e fausia ai le 1,6-octadiene carbon compound sui i vaega alkyl ma aryl i le 3- ma le 8-tulaga. .
1,3-Butadiene o se diene aoga mo le tali a Diels Alder.
E mafai ona faʻaaogaina i le tuʻufaʻatasia o mea nei:

1-Silyl-suia 1,3-butadienes, e le [RuHCl(CO)(PCy3)2]-catalyzed silylative soʻotaga o terminal (E) -1,3-dienes ma vinylsilanes.

Pa'u fa'asusu ma resini vevela.

Dimer disilylate e ala i le tali atu i chlorosilanes.

Octa-2,7-dien-1-ol e ala i le palladium catalyzed-hydrodimerization.
