1,3 I-Butadiene (C4H6)

Iiparameter zobugcisa

I-1,3-Butadiene yi-organic compound enefomyula yekhemikhali ye-C4H6. Yigesi engenambala enevumba elimnandi kwaye kulula ukuyinyibilikisa. Ayinabungozi kangako kwaye ubuthi bayo bufana nobe-ethylene, kodwa inokucaphuka okukhulu kulusu nakwi-mucous membranes, kwaye inefuthe lokudambisa iintlungu xa iphezulu. I-1,3 I-Butadiene iyatsha kwaye ingenza umxube oqhumayo xa ixutywe nomoya; kulula ukuyitshisa nokuqhuma xa ichaphazeleka bubushushu, iintlantsi, amalangatye okanye ii-oxidants; ukuba idibana nobushushu obuphezulu, impendulo ye-polymerization inokwenzeka, ikhuphe ubushushu obuninzi kwaye ibangele ukuqhekeka kwesikhongozeli kunye neengozi zokuqhuma; Inzima kunomoya, inokusasazeka ukuya kumgama omde kwindawo esezantsi, kwaye iya kubangela ukutsha kwakhona xa idibana nomlilo ovulekileyo. I-1,3 i-butadiene iyatshiswa kwaye ibole ibe yi-carbon monoxide kunye ne-carbon dioxide. Ayinyibiliki emanzini, inyibilika kwi-ethanol nakwi-methanol, kwaye inyibilika lula kwii-organic solvents ezininzi ezifana ne-acetone, i-ether kunye ne-chloroform. 1,3 I-Butadiene iyingozi kwindalo esingqongileyo kwaye inokubangela ungcoliseko kwimithombo yamanzi, umhlaba kunye nomoya. 1,3 I-Butadiene ngumvelisi oyintloko werabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, i-neoprene) kunye neeresini ezahlukeneyo ezinokusetyenziswa okubanzi (njenge-ABS resin, i-SBS resin, i-BS resin, i-MBS resin) Izinto eziluhlaza, i-butadiene ikwanokusetyenziswa okuninzi ekuveliseni iikhemikhali ezintle. 1,3 i-butadiene kufuneka igcinwe kwindawo yokugcina izinto epholileyo, enomoya ukuze kufumaneke iigesi ezitshayo. Gcina kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufuneki budlule kwi-30°C. Kufuneka igcinwe ngokwahlukileyo kwii-oxidants, ii-halogens, njl.njl., kwaye uphephe ukugcina okuxutyiweyo. Sebenzisa izibane ezithintela ukuqhuma kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezinokuba neentlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Imveliso yerabha eyenziweyo:

1,3 I-Butadiene yeyona nto iphambili ekuvelisweni kwerabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, kunye ne-neoprene)

②Izinto ezisisiseko zekhemikhali:

I-Butadiene ingasetyenzwa ngakumbi ukuze kuveliswe i-hexamethylene diamine kunye ne-caprolactam, ibe yenye yezinto ezibalulekileyo zokulungisa i-nylon.

③Ikhemikhali entle:

Iikhemikhali ezintle ezenziwe nge-butadiene njengezinto eziluhlaza.
