Izina ryibicuruzwa：1,3-Butadiene

Imiterere ya molekulari ：C4H6

CAS Oya ：106-99-0

Imiterere yibicuruzwa：

Ibikoresho bya Shimi:

1,3-Butadiene ni diene yoroshye. Ni gaze itagira ibara ifite impumuro nziza yoroheje cyangwa lisansi isa kandi idahuye na fenol, dioxyde ya chlorine, umuringa, na crotonaldehyde. Gazi iremereye kuruta ikirere kandi irashobora kugenda hasi; gutwika kure birashoboka. Nibikoresho byingenzi byinganda zikoreshwa nka monomer mugukora reberi yubukorikori. Butadiene nyinshi ni polymerised kugirango ikore reberi. Mugihe polybutadiene ubwayo ari yoroshye cyane, hafi yamazi, ibintu, polymers zateguwe zivanze na butadiene hamwe na styrene cyangwa acrylonitrile, nka ABS, birakomeye kandi byoroshye. Reberi ya Styrene - butadiene nibikoresho bikoreshwa cyane mugukora amapine yimodoka. Umubare muto wa butadiene ukoreshwa mu gukora nylon ukoresheje adiponitrile yo hagati, ibindi bikoresho bya reberi ya sintetike nka chloroprene, na sulpholane ikora. Butadiene ikoreshwa mubikorwa byinganda za cyclododecatriene hakoreshejwe reaction ya trimerisation.

Gusaba:

1,3-Butadiene nigicuruzwa cya peteroli cyabonye catalitike yamenagura amavuta ya naphtha orlight cyangwa na dehydrogenation ya buteneor butane. Ikoreshwa mukubyara butadiene - styrene elastomer (kumapine), syntheticrubber, thelastoplastique elastomers, ibikoresho byo gupakira ibiryo, no mugukora adiponitrile. Ikoreshwa kandi forthe synthesis ya organique na Diels - Aldercondensation.

Elastomeri ya sintetike (styrene-butadiene, polybutadiene, neoprene, nitrile), ibisigarira bya ABS, imiti hagati.
1,3-Butadiene irashobora guhura nibice bine bifatika hamwe na aryl Grignard reagent, hamwe na fluoride ya alkyl imbere ya catalizike ya nikel kugirango ibe karuboni 1,6-octadiene ya karubone isimbuzwa amatsinda ya alkyl na aryl kumwanya wa 3- na 8. .
1,3-Butadiene ni diene yingirakamaro kuri Diels Alder reaction.
Irashobora gukoreshwa muguhuza ibi bikurikira:

1-Silyl yasimbuwe na 1,3-butadienes, na [RuHCl (CO) (PCy3) 2] -gutandukanya sililative guhuza terminal (E) -1,3-diène na vinylsilanes.

Rubber ya sintetike hamwe na resimoplastique.

Ibipimo bitandukanijwe mugukora hamwe na chlorosilane.

Octa-2,7-dien-1-ol ukoresheje palladium catalizike-hydrodimerisation.
