Wasu ilimi game da AIBN (CAS:78-67-1)

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

2.Sifofin sinadarai:

Farin lu'ulu'u masu siffar columnar ko farin lu'ulu'u masu launin foda. Ba ya narkewa a cikin ruwa, yana narkewa a cikin sinadarai masu narkewa kamar methanol, ethanol, acetone, ether, Petroleum ether da aniline.

3. Manufa:

A matsayin wanda ke fara polymerization na vinyl chloride, Vinyl acetate, acrylonitrile da sauran monomers, da kuma a matsayin maganin kumfa don roba da robobi, yawan maganin shine 10% ~ 20%. Hakanan ana iya amfani da wannan samfurin azaman maganin vulcanizing, maganin sinadarai na noma, da kuma matsakaici a cikin haɗakar kwayoyin halitta. Wannan samfurin abu ne mai guba sosai. LD5017.2-25mg/kg na baki a cikin beraye na iya haifar da guba mai yawa ga mutane saboda sakin cyanide na halitta yayin rugujewar zafi.

4. Hanyar samarwa:

Ana amfani da Acetone, hydrazine hydrate da Sodium cyanide a matsayin kayan aiki: zafin amsawar da ke sama shine 55 ~ 60 ℃, lokacin amsawa shine awanni 5, sannan a sanyaya zuwa 25 ~ 30 ℃ na tsawon awanni 2. Lokacin da zafin ya faɗi zuwa ƙasa da 10 ℃, ana shigar da chlorine kuma amsawar tana faruwa ƙasa da 20 ℃ a cikin Littafin Kimiyya. Rabon kayan shine: HCN: acetone: hydrazine = 1L: 1.5036kg: 0.415kg. Acetone cyanohydrin yana amsawa tare da hydrazine hydrate, sannan ya yi oxidize tare da ruwa chlorine ko aminobutyronitrile tare da Sodium hypochlorite.

5. Zafin farawa na mai farawa

AIBN wani abu ne mai matuƙar kyau wanda ke ƙara yawan sinadarin Radical. Idan aka dumama shi zuwa kusan digiri 70 na Celsius, zai ruɓe ya saki nitrogen sannan ya samar da sinadarin free radical (CH3) 2CCN. Tsarin free radical yana da ƙarfi sosai saboda tasirin ƙungiyar cyano. Yana iya amsawa da wani sinadari na halitta kuma ya sake farfaɗowa zuwa sabon sinadari free radical yayin da yake lalata kansa, don haka yana haifar da sinadari na sinadari free radicals (duba Free Radical Reaction). A lokaci guda, ana iya haɗa shi da ƙwayoyin halitta guda biyu ta hanyar Chemicalbook don samar da tetramethyl Succinonitrile (TMSN) tare da guba mai ƙarfi. Lokacin dumama AIBN zuwa 100-107 ° C, yana narkewa kuma yana shiga cikin ruɓewa cikin sauri, yana fitar da iskar nitrogen da wasu sinadarai masu guba na nitrile na halitta, waɗanda kuma suna iya haifar da fashewa da ƙonewa. A hankali yana ruɓewa a zafin ɗaki kuma a adana a ƙasa da digiri 10 na Celsius. A kiyaye nesa da tartsatsin wuta da tushen zafi. Mai guba. Ana narkewa zuwa hydrocyanic acid a cikin kyallen dabbobi kamar jini, hanta, da kwakwalwa.

6. Halayen ajiya da sufuri:

① Rarraba guba: Guba

② Halayen haɗarin fashewa: na iya fashewa idan aka haɗa shi da sinadarai masu hana iskar oxygen; Mai sauƙin oxidizing, rashin kwanciyar hankali, yana ruɓewa sosai a ƙarƙashin zafi, kuma yana fashewa idan aka dumama shi da heptane da acetone

③ Halayen haɗarin ƙonewa: Mai kama da wuta a gaban harshen wuta a buɗe, yanayin zafi mai yawa, da kuma sinadarai masu hana iskar shaka; Yana wargaza iskar gas mai kama da wuta idan aka fallasa ta ga zafi; Konewa yana haifar da hayakin nitrogen oxide mai guba

④ Halayen ajiya da sufuri: iska ta cikin rumbun ajiya, bushewar ƙarancin zafin jiki; A adana daban daga sinadarai masu lalata iska

⑤ Maganin kashe gobara: ruwa, yashi busasshe, carbon dioxide, kumfa, 1211 wakilin kashe gobara
