Zambiri zokhudza AIBN (CAS:78-67-1)

1.Dzina lachingerezi:2,2'-Azobis (2-methylpropionitrile)

2.Mankhwala katundu:

Makatani oyera a columnar kapena white powdery crystals.Sasungunuke m'madzi, sungunuka mu zosungunulira za organic monga methanol, ethanol, acetone, ether, Petroleum ether ndi aniline.

3. Cholinga:

Monga woyambitsa wa polymerization wa vinilu kolorayidi, Vinyl acetate, acrylonitrile ndi monomers ena, komanso thovu wothandizila mphira ndi mapulasitiki, mlingo ndi 10% ~ 20%.Izi zitha kugwiritsidwanso ntchito ngati vulcanizing agent, Agriculture Chemicalbook Medicine, komanso wapakatikati pakupanga organic.Mankhwalawa ndi owopsa kwambiri.Oral LD5017.2-25mg/kg mu mbewa zimatha kuyambitsa kawopsedwe kwambiri kwa anthu chifukwa chotulutsa organic cyanide pakuwola kwamafuta.

4. Njira yopangira:

Acetone, hydrazine hydrate ndi Sodium cyanide amagwiritsidwa ntchito ngati zopangira: zomwe zili pamwambapa kutentha kwa Condensation ndi 55 ~ 60 ℃, nthawi yochitira ndi 5h, kenako kuzirala mpaka 25 ~ 30 ℃ kwa 2h.Kutentha kumatsika mpaka pansi pa 10 ℃, chlorine imayambitsidwa ndipo zomwe zimachitika pansi pa 20 ℃ mu Chemicalbook.Chiŵerengero cha zinthu ndi: HCN: acetone: hydrazine = 1L: 1.5036kg: 0.415kg.Acetone cyanohydrin imakumana ndi hydrazine hydrate, kenako oxidize ndi madzi chlorine kapena aminobutyronitrile ndi Sodium hypochlorite.

5.Kuyambitsa kutentha kwa woyambitsa

AIBN ndiwoyambitsa kwambiri Radical.Ikatenthedwa mpaka pafupifupi 70 ° C, imawola ndikutulutsa nayitrogeni ndikupanga free radical (CH3) 2CCN.Ma radical aulere amakhala okhazikika chifukwa cha chikoka cha gulu la cyano.Itha kuchitapo kanthu ndi gawo lina la organic ndikusinthanso kukhala free radical yatsopano kwinaku ikudziwononga yokha, motero imayambitsa ma chain reaction of free radicals (onani Free Radical Reaction).Nthawi yomweyo, imathanso kuphatikizidwa ndi mamolekyu awiri a Chemicalbook kuti apange tetramethyl Succinonitrile (TMSN) yokhala ndi kawopsedwe kamphamvu.Ikatenthetsa AIBN mpaka 100-107 ° C, imasungunuka ndikuwola mwachangu, kutulutsa mpweya wa nayitrogeni ndi mankhwala angapo oopsa a nitrile, omwe angayambitsenso kuphulika ndi kuyaka.Pang'onopang'ono kuwola pa firiji ndi sitolo m'munsimu 10 ° C. Khalani kutali ndi zipsera ndi kutentha magwero.Zapoizoni.Amapangidwa mu hydrocyanic acid mu minofu ya nyama monga magazi, chiwindi, ndi ubongo.

6.Kusungirako ndi mawonekedwe amayendedwe:

① Gulu la kawopsedwe: Poizoni

② Zowopsa zophulika: zimatha kuphulika zikasakanikirana ndi okosijeni;Yosavuta kutulutsa okosijeni, yosakhazikika, imawola kwambiri pakutentha, ndipo imaphulika Chemicalbook ikatenthedwa ndi heptane ndi acetone.

③ Makhalidwe owopsa oyaka: Kuyaka pamaso pa malawi otseguka, kutentha kwambiri, ndi okosijeni;Imawola mpweya woyaka moto ukayaka;Kuwotcha kumatulutsa utsi wapoizoni wa nitrogen oxide

④ Makhalidwe osungira ndi mayendedwe: mpweya wabwino wa nyumba yosungiramo katundu, kuyanika kwapang'onopang'ono;Sungani mosiyana ndi zotsekemera

⑤ Chozimitsa: madzi, mchenga wouma, mpweya woipa, thovu, 1211 chozimitsa
