Ubumenyi bumwe na bumwe kuri AIBN (CAS: 78-67-1)

1.Izina ry'Icyongereza:2,2′-Azobis (2-methylpropionitrile)

2.Imiterere y'ibinyabutabire:

Amakristu y'umweru cyangwa amakristu y'umweru afite ifu. Ntishobora gushonga mu mazi, ishonga mu bintu bishongesha nk'ibinyabutabire nka methanol, ethanol, acetone, ether, ether ya peteroli na aniline.

3. Intego:

Nk'ikintu gitangira gukora polimeri ya vinyl chloride, Vinyl acetate, acrylonitrile n'izindi monomer, ndetse n'ikintu gitanga ifuro ku rubura na pulasitiki, ingano ni 10% ~ 20%. Iki gicuruzwa gishobora kandi gukoreshwa nk'ikintu gitera imyuka, umuti w'ubuhinzi, ndetse n'ikintu gikoreshwa mu gukora organic synthesis. Iki gicuruzwa ni ikintu gifite uburozi bwinshi. LD5017.2-25mg / kg mu mbeba ishobora gutera uburozi bukomeye ku bantu bitewe no kurekura cyanide organic mu gihe cyo kubora kw'ubushyuhe.

4. Uburyo bwo gukora:

Asetone, hydrazine hydrate na Sodium cyanide bikoreshwa nk'ibikoresho fatizo: ubushyuhe bwavuzwe haruguru bwo guhumeka ni 55 ~ 60 ℃, igihe cyo guhumeka ni amasaha 5, hanyuma bigakonja kugeza kuri 25 ~ 30 ℃ mu gihe cy'amasaha 2. Iyo ubushyuhe bugabanutse bukagera munsi ya 10 ℃, chlorine irashyirwamo kandi ingaruka zikaba munsi ya 20 ℃ muri Chemicalbook. Igipimo cy'ibikoresho ni: HCN: asetone: hydrazine = 1L: 1.5036kg: 0.415kg. Asetone cyanohydrin ikorana na hydrazine hydrate, hanyuma igakora oxidize hamwe na chlorine y'amazi cyangwa aminobutyronitrile hamwe na Sodium hypochlorite.

5. Ubushyuhe bw'itangizwa ry'itangizwa ry'itangizwa

AIBN ni imashini nziza cyane ya Radical. Iyo ishyushye kugeza kuri 70 ° C, irabora ikarekura azote kandi ikabyara free radical (CH3) 2CCN. Free radical irahamye bitewe n'ingaruka za cyano group. Ishobora gukorana n'indi substrate y'ibinyabuzima ikavugurura ikaba free radical nshya mu gihe yiyica, bityo igatera Chain reaction ya free radicals (reba Free Radical Reaction). Muri icyo gihe, ishobora kandi guhuzwa na molekile ebyiri na Chemicalbook kugira ngo ikore tetramethyl Succinonitrile (TMSN) ifite uburozi bukomeye. Iyo ishyushye AIBN kugeza kuri 100-107 ° C, irashonga kandi ikarangirika vuba, isohora imyuka ya azote n'ibintu byinshi bya nitrile by'uburozi, bishobora no gutera guturika no gushya. Irabora buhoro buhoro ku bushyuhe bw'icyumba kandi ikabikwa munsi ya 10 ° C. Bika kure y'ibishashi n'amasoko y'ubushyuhe. Uburozi. Ihinduka aside hydrocyanic mu nyamaswa nk'amaraso, umwijima, n'ubwonko.

6. Ibiranga ububiko n'ubwikorezi:

① Ishyirwa mu byiciro ry'uburozi: Uburozi

② Ibiranga ingaruka z'iturika: rishobora guturika iyo rivanze na okisideri; Biroroshye kuri okisideri, ntirihindagurika, ribora cyane iyo rishyushye, kandi rigaturika Chemicalbook iyo rishyushye na heptane na acetone

③ Ibiranga ingaruka zo gutwika: Ishobora gushya iyo hari umuriro ufunguye, ubushyuhe bwinshi, n'ibintu bigabanya ogisijeni; Iboza imyuka ishya iyo ihuye n'ubushyuhe; Gutwika bitanga umwotsi wa azote okiside y'uburozi

④ Ibiranga ububiko n'ubwikorezi: uburyo bwo guhumeka mu bubiko, kuma mu bushyuhe buke; Bika ukwabyo mu bintu birwanya ogisijeni

⑤ Ikintu kizimya umuriro: amazi, umucanga wumye, dioxyde de carbone, ifuro, ikintu kizimya umuriro cya 1211
