1.Sunan Ingilishi:2,2'-Azobis (2-methylpropionitrile)

2.Abubuwan sinadaran:

Farin lu'ulu'u na ginshiƙai ko farin lu'ulu'u na foda.Mai narkewa a cikin ruwa, mai narkewa a cikin kaushi na halitta kamar methanol, ethanol, acetone, ether, Petroleum ether da aniline.

3.Manufa:

A matsayin mai ƙaddamarwa don polymerization na vinyl chloride, Vinyl acetate, acrylonitrile da sauran monomers, da kuma wakili mai kumfa don roba da robobi, sashi shine 10% ~ 20%.Hakanan za'a iya amfani da wannan samfurin azaman wakili mai ɓarna, maganin littafin sinadarai na aikin gona, da kuma tsaka-tsaki a cikin haɗin kwayoyin halitta.Wannan samfurin abu ne mai guba sosai.Oral LD5017.2-25mg/kg a cikin mice na iya haifar da guba mai mahimmanci ga mutane saboda sakin kwayoyin cyanide a lokacin bazuwar thermal.

4.Hanyar samarwa:

Acetone, hydrazine hydrate da sodium cyanide ana amfani da su azaman albarkatun ƙasa: sama da zafin jiki na Condensation shine 55 ~ 60 ℃, lokacin amsawa shine 5h, sannan sanyaya zuwa 25 ~ 30 ℃ don 2h.Lokacin da zafin jiki ya faɗi ƙasa da 10 ℃, ana gabatar da chlorine kuma abin da ke faruwa yana faruwa ƙasa da 20 ℃ a cikin Littafin Chemical.Matsakaicin abu shine: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg.Acetone cyanohydrin yana amsawa tare da hydrazine hydrate, sannan yana oxidizes da ruwa chlorine ko aminobutyronitrile tare da Sodium hypochlorite.

5.Initiation zafin jiki na mai farawa

AIBN ƙwararren ƙwararren ƙwararren Radical ne.Lokacin da zafi ya kai kimanin 70 ° C, zai bazu ya saki nitrogen kuma ya haifar da 2CCN kyauta (CH3).Masu fafutuka na 'yanci suna da kwanciyar hankali saboda tasirin ƙungiyar cyano.Yana iya amsawa tare da wani madaidaicin kwayoyin halitta kuma ya sake farfadowa cikin sabon tsattsauran ra'ayi yayin da yake halaka kansa, don haka yana haifar da amsawar Sarkar radicals kyauta (duba Ra'ayin Radical Kyauta).A lokaci guda kuma, ana iya haɗa shi da kwayoyin halitta guda biyu ta Chemicalbook don samar da tetramethyl Succinonitrile (TMSN) tare da guba mai ƙarfi.Lokacin dumama AIBN zuwa 100-107 ° C, yana narkewa kuma yana saurin rubewa, yana fitar da iskar nitrogen da mahaɗan nitrile masu guba da yawa, waɗanda kuma na iya haifar da fashewa da ƙonewa.Sannu a hankali bazuwa a dakin da zafin jiki kuma adana a ƙasa 10 ° C. Ka nisanci tartsatsi da tushen zafi.Mai guba.Metabolized zuwa hydrocyanic acid a cikin kyallen jikin dabba kamar jini, hanta, da kwakwalwa.

6.Storage da sufuri halaye:

① Rarraba guba: Guba

② Halayen haɗari masu fashewa: na iya fashewa lokacin da aka haxa su da oxidants;Sauƙi don oxidize, rashin kwanciyar hankali, da ƙarfi yana bazuwa ƙarƙashin zafi, kuma yana fashe Littafin sinadarai lokacin zafi da heptane da acetone.

③ Haɗarin haɗari na flammability: Flammable a gaban buɗewar harshen wuta, yanayin zafi mai zafi, da ma'aikatan oxidizing;Yana lalata iskar gas masu ƙonewa lokacin da aka fallasa ga zafi;Konewa yana haifar da hayaki mai guba na nitrogen oxide

④ Halayen ajiya da sufuri: iskar shago, bushewar ƙarancin zafi;Ajiye dabam daga oxidants

⑤ Kashewa wakili: ruwa, busassun yashi, carbon dioxide, kumfa, 1211 extinguishing wakili
