Khoom npe:1,3-butadiene

Molecular hom:C4H6

Cas:106-99-0

Khoom molecular qauv:

Tshuaj Tshuaj Muaj Zog:

1,3-butadiene yog qhov sib piv uas yooj yim. Nws yog cov roj uas tsis muaj kob uas muaj ntxhiab tsw ntxhiab lossis zoo li tsw ntxhiab thiab tsis sib xws nrog Phenol, tooj liab, thiab crotonaldehyde. Cov pa roj hnyav dua cua thiab tej zaum yuav taug kev hauv av; nyob deb qhov kev tiv thaiv yog ua tau. Nws yog ib qho kev lag luam muaj tshuaj lom siv los ua monomer hauv cov roj hmab ntau lawm. Feem ntau Butadiene yog polymerised los tsim cov roj hmab siv hluav taws xob hluavtaws. Thaum polybutadiene nws tus kheej yog qhov muag muag heev, cov khoom siv, polymers npaj los ntawm kev sib xyaw ua ke lossis acrylonitrile, xws li abrastic thiab ywj. Styrene-butadiene roj hmab yog cov khoom siv feem ntau siv rau kev tsim cov log tsheb ntau lawm. Cov roj hmab me me yog siv los ua cov nylon ntawm qib nrab adiponitrile, lwm cov khoom siv roj hmab xws li chloroprene cov khoom xws li chloroprene, thiab cov kuab tshuaj sulphourene, thiab cov kuab tshuaj sulphourene. Butadiene yog siv nyob rau hauv kev lag luam ntau lawm ntawm cyclododecatriene ntawm kev txiav txim siab.

Daim Ntawv Thov:

1,3-butadiene yog cov khoom lag luam roj hmab tau txais kev tawg ntawm naphalha backing ntawm naphtha roj los yog los ntawm dehydrogenation ntawm buteneor buteneor. Nws yog siv los tsim Butadiene Elastomer (rau cov log tsheb), hluavtaws elastomers, thermoplacastic elastomers, cov ntaub ntawv muab cov ntaub ntawv, thiab hauv cov khoom lag luam adiponitrile. Nws tseem siv rau cov xwm txheej hluavtaws los ntawm Diels-Aldercondensation.

Cov khoom siv hluavtaws Elastomers (STyrene-butadiene, polybutadiene, neoprene, nitriles, nitriles), pib ua hauj lwm), chemical nrab.
1,3-Butadiene tuaj yeem txuas ntxiv plaub-feem txuas nrog Arignard Reagents, thiab Alkyl pawg ntawm cov pab pawg alkyl thiab aryl ntawm 3- thiab 8-txoj haujlwm.
1,3-butadiene yog ib qho kev pab tau zoo rau diels alder cov nyom.
Nws yuav raug siv rau hauv cov hluavtaws ntawm cov hauv qab no:

1-siilyl-hloov 1,3-butadienes, los ntawm [ruild (pev) (e) -1,3-dienes nrog vinylsilanes.

Khoom cua roj hmab thiab thermoplastic resins.

Daus Dimers los ntawm reacting nrog chlorosilanes.

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