1,3 Butadiene (C4H6)

Zosintha zaukadaulo

1,3-Butadiene ndi mankhwala omwe ali ndi mankhwala a C4H6. Ndi gasi wopanda mtundu wokhala ndi fungo lonunkhira pang'ono ndipo ndi wosavuta kusungunuka. Ndiwochepa poizoni ndipo kawopsedwe kake ndi kofanana ndi ethylene, koma imakhala ndi mkwiyo wamphamvu pakhungu ndi mucous nembanemba, ndipo imakhala ndi mankhwala oletsa kupweteka kwambiri. 1,3 Butadiene ndi yoyaka ndipo imatha kupanga chisakanizo chophulika chikasakanizidwa ndi mpweya; zimakhala zosavuta kuyaka ndi kuphulika pamene zimatenthedwa ndi kutentha, moto, malawi amoto kapena oxidants; ikakumana ndi kutentha kwakukulu, ma polymerization amatha kuchitika, kutulutsa kutentha kwambiri ndikupangitsa kuti chidebe ching'ambikake ndi ngozi zaphulika; Ndi yolemera kuposa mpweya, imatha kufalikira kutali kwambiri pamalo otsika, ndipo imatha kuyambitsa moto ikakumana ndi lawi lotseguka. 1,3 butadiene imawotchedwa ndikuwola kukhala carbon monoxide ndi carbon dioxide. Sisungunuke m'madzi, sungunuka mu Mowa ndi methanol, ndipo sungunuka mosavuta mu zosungunulira zambiri organic monga acetone, etha ndi chloroform. 1,3 Butadiene ndi yovulaza chilengedwe ndipo ingayambitse kuipitsa madzi, nthaka ndi mpweya. 1,3 Butadiene ndiye amapanga mphira wopangira (rabara ya styrene butadiene, rabala ya butadiene, mphira wa nitrile, neoprene) ndi ma resin osiyanasiyana okhala ndi ntchito zosiyanasiyana (monga utomoni wa ABS, utomoni wa SBS, utomoni wa BS, utomoni wa MBS) zinthu, butadiene alinso ntchito zambiri popanga mankhwala abwino. 1,3 butadiene iyenera kusungidwa m'nyumba yosungiramo mpweya yozizira komanso mpweya woyaka mpweya. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa mosiyana ndi ma okosijeni, ma halojeni, ndi zina zambiri, ndikupewa kusungirako kosakanikirana. Gwiritsani ntchito magetsi osaphulika komanso mpweya wabwino. Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kuphulika. Malo osungiramo zinthu ayenera kukhala ndi zida zothandizira zadzidzidzi zomwe zatuluka.

Ntchito:

①Kupanga mphira:

1,3 Butadiene ndiye chinthu chachikulu chopangira mphira wopangira (rabala wa styrene butadiene, mphira wa butadiene, rabala wa nitrile, ndi neoprene)

②Zida zopangira mankhwala:

Butadiene imatha kukonzedwanso kuti ipange hexamethylene diamine ndi caprolactam, kukhala imodzi mwazinthu zofunika kwambiri popanga nayiloni.

③mankhwala abwino:

Mankhwala abwino opangidwa kuchokera ku butadiene ngati zopangira.
