Olunye ulwazi malunga ne-AIBN (i-CAS: 78-67-1)

1.Igama lesiNgesi:I-2,2'-Azobis (2-Methylpropiininderle)

2.Iipropathi zeekhemikhali:

Ikristali ye-White Colminar okanye iikristali ezimhlophe ezimhlophe. I-insolling emanzini, inyibilikiswa kwiinyibiliki ezifana ne-methanol, ethanol, i-acetone, i-ether, ipetroleum ekrway kunye ne-petroleum ether kunye ne-petroleum ether kunye ne-petroleum ekrwada.

3.Purive:

Njengomqalisi we-Polymerization ye-vinyl hloride, i-vinyl acetate, i-acryloniate kunye nezinye izalamane, kunye nearhente yerabha yerabha kunye ne-10% ~ 20%. Le mveliso inokusetyenziswa njengearhente yobuqhetseba, incwadana enemichiza yezolimo, kunye ne-ofisi ephakathi kwi-orth synthesic synthesi. Le mveliso yinto enetyhefu kakhulu. I-OIL LL5017.2-22-25mg / kg kwiimpuku zinokubangela ukuba ityhefu ephambili ebantwini ngenxa yokukhutshwa kwe-cyside ye-organic ngexesha lokuhombisa.

Indlela yokuBenza umveliso:

I-Acetone, i-Hydrazine i-hydrate kunye nesodium ye-sodium isetyenziswa njengezixhobo zokuhamba-mba: I-60 ℃, ukupholisa ukuya kwi-25 ~ Xa iqondo lobushushu liye laya ngaphantsi kwe-10 ℃, i-chlorine yaziswa kwaye impendulo yenzeka ngezantsi kwe-20 ℃ kwincwadana yekhemikhali. Umyinge wezinto ezibonakalayo: HCN: Acetone: I-Acetone: Hydrazine = 1l: 1.5036kg: 0.415kg. I-Acetone ye-Acetone ye-Acenehydrin i-Hydrazine Hydrate, kwaye emva koko i-oxidd nge-chlorine ye-florine okanye i-aminobynindirmie ye-Sodium hypoctlorite.

Iqondo lobushushu le-timinator

I-AIBN yeyokwanela i-ABN. Xa ifudumele malunga ne-70 ° C, iya kuyenza kwaye ikhuphe i-nitrogen kwaye ivelise i-radical yasimahla (CH3) 2ccn. I-radical yasimahla ilusizi kakhulu ngenxa yempembelelo yeqela le-Syano. Inokusabela kwelinye i-organic kwaye iphinde iphinde ibe yi-radical entsha yasimahla ngelixa ihlanjululwa, ngenxa yoko iqhubela phambili i-chain rain radicals (jonga ukuphendula okukhulu). Kwangelo xesha, oko kunokuqhubela phambili neemolekyuli ezimbini ngencwadana yemichiza ukuvelisa i-ticramethyl sutramethyl succinenitriitriitriitriitrile (i-TMSN) enobunzima obuqinileyo. Xa ukufudumeza i-Aibn ukuya kwi-100-107 ° C, iyanyibilika kwaye ikhuphe igesi ye-nitrogen, irhasi yetyhefu enetyhefu yetyhefu, enokubangela ukuqhuma kunye nokusebenza. Ukucotha kancinci kubushushu begumbi kunye nokugcina ngaphantsi kwe-10 ° C. Hlala kude neentlantsi kunye nemithombo yobushushu. Inetyhefu. Imetabolded kwi-hydrocynic acid kwizicubu zezilwanyana ezinje ngegazi, isibindi, kunye nengqondo.

6.Ststorage kunye neempawu zothutho:

Ukuhlelwa kwetyhefu: Ityhefu

② Iimpawu zengozi yokuqhuma: inokuqhuma xa idityaniswa nee-oxidants; Kulula ukunyanzela, ukungazinzisi, kubola iiviwusa phantsi kobushushu, kwaye kuqhume iincwadi zekhemikhali xa ushushu kunye ne-hepthane kunye ne-acetone

Iimpawu ezinobungozi obuyisiseko: Ukubola kweegesi ezinokutsha xa zityhilwe kubushushu; Ukutshisa kuvelisa ityhefu yetyhefu ye-windon yesibhokhwe

Iimpawu zokugcina kunye nezothutho Gcina ngokwahlukeneyo kwii-oxidants

⑤ Ukucima iarhente: amanzi, isanti eyomileyo, ikharbon diokside, i-foam, i-1211 iarhente yokucima iarhente
