1,3 Butadiene (C4H6)

Technical parameters

1,3-Butadiene is an organic compound ine kemikari yeC4H6. Igasi risina ruvara rine kakunhuhwirira uye riri nyore kunyungudika. Iyo haina muchetura uye huturu hwayo hwakafanana neiyo ethylene, asi ine kutsamwa kwakasimba kune ganda uye mucous membranes, uye ine anesthetic effect pakukwirira kwakanyanya. 1,3 Butadiene inopfuta uye inogona kugadzira musanganiswa unoputika kana yasanganiswa nemhepo; zviri nyore kupisa uye kuputika kana zvichiratidzwa nekupisa, mazhenje, moto kana oxidants; kana ikasangana nekupisa kwakanyanya, polymerization reaction inogona kuitika, kuburitsa kupisa kwakawanda uye kukonzera kuputika kwemudziyo uye tsaona dzekuputika; Iyo Inorema kupfuura mweya, inogona kupararira kusvika kure kure munzvimbo yakaderera, uye inokonzeresa backflame kana ikasangana nemurazvo wakavhurika. 1,3 butadiene inopiswa uye yakaora kuita kabhoni monoxide uye carbon dioxide. Iyo hainyungudike mumvura, inonyungudika mu ethanol uye methanol, uye inonyungudika zviri nyore mune zvakawanda organic solvents senge acetone, ether uye chloroform. 1,3 Butadiene inokuvadza kune zvakatipoteredza uye inogona kukonzera kusvibiswa kumitumbi yemvura, ivhu uye mhepo. 1,3 Butadiene ndiyo inonyanya kugadzira rabha rekugadzira (styrene butadiene rubber, butadiene rubber, nitrile rubber, neoprene) uye resin dzakasiyana dzine zvakasiyana-siyana zvekushandisa (zvakadai seABS resin, SBS resin, BS resin, MBS resin) zvinhu, butadiene zvakare ine zvakawanda zvinoshandiswa mukugadzirwa kwemakemikari akanaka. 1,3 butadiene inofanira kuchengetwa munzvimbo inotonhorera, ine mhepo yekuchengetera gasi rinopfuta. Ramba kure nemoto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Inofanirwa kuchengetwa zvakasiyana kubva kune oxidants, halogens, nezvimwewo, uye kudzivirira kusanganiswa kuchengetedza. Shandisa mwenje unodzivirira kuputika uye nzvimbo dzekupinza mhepo. Zvinorambidzwa kushandisa michina michina uye maturusi anowanzo kupfava. Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa neyakadonha yekurumidzira kurapwa michina.

Application:

①Synthetic rabha kugadzirwa:

1,3 Butadiene ndiyo inonyanya kushandiswa pakugadzirwa kwerabha yakagadzirwa (styrene butadiene rubber, butadiene rubber, nitrile rubber, uye neoprene)

②Basic kemikari mbishi zvinhu:

Butadiene inogona kushandiswazve kugadzira hexamethylene diamine uye caprolactam, ichiva chimwe chezvinhu zvakakosha zvekugadzira naironi.

③Kemikari yakanaka:

Makemikari akanaka akagadzirwa kubva kubutadiene semidziyo.
