1.3 Butadiene (C4H6) hmoov

Technical parameters

1,3-Butadiene yog cov organic compound nrog cov tshuaj formula C4H6. Nws yog cov roj tsis muaj xim nrog cov ntxhiab tsw me ntsis thiab yooj yim rau liquefy. Nws tsis tshua muaj tshuaj lom thiab nws cov tshuaj toxicity zoo ib yam li cov ethylene, tab sis nws muaj zog khaus rau ntawm daim tawv nqaij thiab mucous daim nyias nyias, thiab muaj cov tshuaj loog nyob rau hauv siab concentrations. 1,3 Butadiene yog flammable thiab tuaj yeem tsim cov khoom tawg thaum sib xyaw nrog huab cua; nws yog ib qho yooj yim rau hlawv thiab tawg thaum raug tshav kub, sparks, nplaim taws los yog oxidants; Yog tias nws ntsib cov cua sov siab, cov tshuaj tiv thaiv polymerization yuav tshwm sim, tso cua sov ntau thiab ua rau lub thawv tawg thiab tawg tawg; Nws hnyav dua li huab cua, nws tuaj yeem kis mus rau qhov deb ntawm qhov chaw qis, thiab nws yuav ua rau rov qab los thaum nws ntsib cov nplaim taws qhib. 1,3 butadiene raug hlawv thiab decomposed rau hauv carbon monoxide thiab carbon dioxide. Nws yog insoluble hauv dej, soluble hauv ethanol thiab methanol, thiab yooj yim soluble nyob rau hauv feem ntau organic solvents xws li acetone, ether thiab chloroform. 1,3 Butadiene muaj teeb meem rau ib puag ncig thiab tuaj yeem ua rau muaj kuab paug rau hauv dej, av thiab huab cua. 1,3 Butadiene yog tus tsim khoom tseem ceeb ntawm cov roj hmab hluavtaws (styrene butadiene roj hmab, butadiene roj hmab, nitrile roj hmab, neoprene) thiab ntau yam resins nrog ntau hom kev siv (xws li ABS resin, SBS resin, BS resin, MBS resin) Cov khoom nyoos cov khoom siv, butadiene kuj muaj ntau yam siv hauv kev tsim cov tshuaj zoo. 1,3 butadiene yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua txias rau cov pa taws. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais tawm ntawm oxidants, halogens, thiab lwm yam, thiab tsis txhob sib xyaw cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua. Nws yog txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas nquag ua rau lub txim taws. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Synthetic roj hmab ntau lawm:

1,3 Butadiene yog cov khoom siv tseem ceeb rau kev tsim cov roj hmab hluavtaws (styrene butadiene roj hmab, butadiene roj hmab, nitrile roj hmab, thiab neoprene)

②Basic chemical raw khoom:

Butadiene tuaj yeem ua tiav ntxiv los tsim hexamethylene diamine thiab caprolactam, dhau los ua ib qho tseem ceeb raw cov ntaub ntawv rau kev npaj nylon.

③ Cov tshuaj zoo:

Cov tshuaj zoo ua los ntawm butadiene ua raw khoom.
