1.Ingoa Ingarihi:2,2′-Azobis(2-methylpropionitrile)
2.Ngā āhuatanga matū:
He tioata poutū mā, he tioata paura mā rānei. Kāore e rewa i te wai, engari ka rewa i roto i ngā whakarewa waro pērā i te methanol, te etanoru, te acetone, te ether, te petroleum ether me te aniline.
3. Kaupapa:
Hei tīmatanga mō te whakapūhuitanga o te vinyl chloride, te vinyl acetate, te acrylonitrile me ētahi atu monomers, me te mea hei whakapūpū i te rapa me te kirihou, ko te horopeta he 10%~20%. Ka taea hoki te whakamahi i tēnei hua hei mea whakapūpū, hei rongoā matū ahuwhenua, hei takawaenga hoki i roto i te hanganga rauropi. He matū tino paitini tēnei hua. Ka taea e te LD5017.2-25mg/kg ā-waha i roto i ngā kiore te whakararu i te paitini nui ki te tangata nā te tukunga o te cyanide rauropi i te wā e pirau ana.
4. Tikanga whakaputa:
Ko te acetone, te hydrazine hydrate me te Sodium cyanide ngā rauemi mata: ko te pāmahana tauhohenga Condensation i runga ake nei ko te 55~60 ℃, ko te wā tauhohenga ko te 5 hāora, kātahi ka whakamatao ki te 25~30 ℃ mō te 2 hāora. Ina heke te pāmahana ki raro iho i te 10 ℃, ka tāpirihia he chlorine, ā, ka puta te tauhohenga i raro iho i te 20 ℃ i roto i te Chemicalbook. Ko te ōwehenga rauemi ko: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg. Ka tauhohe te acetone cyanohydrin ki te hydrazine hydrate, kātahi ka waikura ki te chlorine wai, ki te aminobutyronitrile rānei ki te Sodium hypochlorite.
5. Te pāmahana tīmatanga o te kaiwhakaoho
He tino pai rawa atu te AIBN hei whakaoho i ngā matūriki. Ina whakamahanatia ki te 70°C pea, ka pirau, ka tukuna te hauota, ka puta he matūriki kore utu (CH3) 2CCN. He pumau te matūriki kore utu nā te awe o te rōpū cyano. Ka taea e ia te tauhohe ki tētahi atu matūriki waro, ka hanga hou hei matūriki kore utu hou, me te whakangaro i a ia anō, ā, ka tīmata te Tauhohenga mekameka o ngā matūriki kore utu (tirohia te Tauhohenga Mātiti Kore Utu). I taua wā anō, ka taea hoki te hono atu ki ngā ngota e rua e Chemicalbook hei whakaputa i te tetramethyl Succinonitrile (TMSN) me te paitini kaha. Ina whakamahanatia te AIBN ki te 100-107°C, ka rewa, ka tere te pirau, ka tukuna te hau hauota me ētahi matū nitrile waro paitini, ka taea hoki te pahū me te mura. Ka pirau mārire i te pāmahana rūma, ā, rongoatia ki raro i te 10°C. Puritia kia matara atu i ngā mura me ngā pūtake wera. Paitini. Ka hurihia hei waikawa hydrocyanic i roto i ngā kiko kararehe pēnei i te toto, te ate, me te roro.
6. Ngā āhuatanga rokiroki me te kawe:
① Whakarōpūtanga paitini: Paitini
② Ngā āhuatanga mōrearea pahūtanga: ka pahū ina konatunatua ki ngā waikura; He ngāwari ki te waikura, kāore i te pumau, ka pirau kaha i raro i te wera, ā, ka pahū ina werahia ki te heptane me te acetone
③ Ngā āhuatanga mōrearea mura: Ka mura i te aroaro o ngā mura tuwhera, ngā pāmahana teitei, me ngā matū whakahāngai; Ka pirau ngā hau mura ina pāngia e te wera; Ka puta he paowa hauota waikura paitini ina tahuna
④ Ngā āhuatanga rokiroki me te kawe: te hauhautanga o te whare putunga, te whakamaroke i te pāmahana iti; Rokiroki motuhake mai i ngā waikura
⑤ Kaiwhakaiti ahi: wai, onepu maroke, hauhā waro, pahuka, kaiwhakaiti ahi 1211
