1,3 Butadiene (C4H6)

Iiparamitha zobugcisa

I-1,3-Butadiene i-organic compound kunye ne-chemical formula ye-C4H6. Yirhasi engenambala enevumba elimnandi kwaye kulula ukuyinyibilikisa. Inobuthi obuncinci kwaye ubuthi bayo bufana ne-ethylene, kodwa inomsindo onamandla kwesikhumba kunye ne-mucous membranes, kwaye inefuthe le-anesthetic kwiindawo eziphezulu. 1,3 I-Butadiene iyatsha kwaye inokwenza umxube oqhumayo xa ixutywe nomoya; kulula ukutshisa kunye nokuqhuma xa ibonakaliswe kubushushu, iintlantsi, amadangatye okanye i-oxidants; ukuba idibana nobushushu obuphezulu, i-polymerization reaction ingenzeka, ikhulule ubushushu obuninzi kwaye ibangele ukugqabhuka kwesikhongozeli kunye neengozi zokudubula; Inzima kunomoya, inokunwenwela kumgama omde kwindawo esezantsi, kwaye iya kubangela umva xa idibana nedangatye elivulekileyo. I-1,3 butadiene itshiswa kwaye ichithwa kwi-carbon monoxide kunye ne-carbon dioxide. Ayinyibiliki emanzini, inyibilika kwi-ethanol kunye ne-methanol, kwaye i-soluble ngokulula kwizinto ezininzi ze-organic solvents ezifana ne-acetone, i-ether kunye ne-chloroform. I-1,3 i-Butadiene iyingozi kwindalo kwaye inokubangela ungcoliseko kwimizila yamanzi, umhlaba kunye nomoya. I-1,3 i-Butadiene ngumvelisi oyintloko we-rubber yokwenziwa (i-rabha ye-styrene butadiene, i-rubber butadiene, i-rubber ye-nitrile, i-neoprene) kunye neentlobo ezahlukeneyo ze-resin ezinoluhlu olubanzi lwezinto ezisetyenziswayo (ezifana ne-ABS resin, i-SBS resin, i-BS resin, i-MBS resin) izinto eziphathekayo, ibutadiene nayo ineendlela ezininzi zokusetyenziswa kwimveliso yeekhemikhali ezintle. I-1,3 i-butadiene kufuneka igcinwe kwindawo epholileyo, yokugcina umoya kwiigesi ezinokutsha. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufunekanga budlule kuma-30°C. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, halogens, njl., kwaye ugweme ukugcinwa okuxubileyo. Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezixhomekeke kwiintlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Imveliso yerabha eyenziweyo:

I-1,3 i-Butadiene iyona nto iphambili kwimveliso yerabha yokwenziwa (i-rabha ye-styrene butadiene, i-rubber butadiene, i-nitrile rubber, kunye ne-neoprene)

②Imathiriyeli ekrwada yeekhemikhali:

I-Butadiene inokuqhubekekiswa ngakumbi ukuvelisa i-hexamethylene diamine kunye ne-caprolactam, ibe yenye yezinto ezibalulekileyo zokulungiswa kwenayiloni.

③Ikhemikhali entle:

Iikhemikhali ezintle ezenziwe ngebutadiene njengezinto eziluhlaza.
