ʻO kekahi ʻike e pili ana iā AIBN (CAS:78-67-1)

1.inoa Pelekane:2,2′-Azobis(2-methylpropionitrile)

2.Nā waiwai kemika:

Nā kristal kolamu keʻokeʻo a i ʻole nā ​​kristal pauka keʻokeʻo.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka methanol, ethanol, acetone, ether, Petroleum ether a me aniline.

3. Ke kumu:

Ma ke ʻano he mea hoʻomaka no ka polymerization o ka vinyl chloride, Vinyl acetate, acrylonitrile a me nā monomers ʻē aʻe, a me ka mea hoʻoheheʻe ʻana no ka lāʻau a me nā plastics, ʻo 10% ~ 20%.Hiki ke hoʻohana ʻia kēia huahana ma ke ʻano he mea vulcanizing agent, lāʻau lāʻau chemicalbook mahiʻai, a me kahi mea waena i ka synthesis organik.He mea ʻawaʻawa kēia huahana.Hiki i ka waha LD5017.2-25mg/kg i nā ʻiole ke hoʻomake nui i nā kānaka ma muli o ka hoʻokuʻu ʻia ʻana o ka cyanide organik i ka wā o ka decomposition thermal.

4.Production hana:

Hoʻohana ʻia ka Acetone, hydrazine hydrate a me Sodium cyanide e like me nā mea maka: ʻo ka mahana o ka hopena Condensation ma luna o 55 ~ 60 ℃, ʻo ka manawa hoʻonā he 5h, a laila hoʻomaha i 25 ~ 30 ℃ no 2h.Ke hāʻule ka mahana ma lalo o 10 ℃, hoʻokomo ʻia ka chlorine a hana ʻia ka hopena ma lalo o 20 ℃ ma Chemicalbook.ʻO ka lākiō mea: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg.Hoʻopili ʻo Acetone cyanohydrin me ka hydrazine hydrate, a laila hoʻokahe ʻia me ka chlorine wai a i ʻole aminobutyronitrile me Sodium hypochlorite.

5.Initiation wela o ka initiator

ʻO AIBN kahi mea hoʻomaka Radical maikaʻi loa.Ke hoʻomehana ʻia a hiki i ka 70 ° C, e decompose a hoʻokuʻu i ka nitrogen a hoʻoulu i ka radical manuahi (CH3) 2CCN.Paʻa ka radical manuahi ma muli o ka mana o ka hui cyano.Hiki iā ia ke hana me kekahi substrate organik a hana hou i loko o kahi radical manuahi hou i ka wā e hoʻopau ai iā ia iho, no laila e hoʻoulu ai i ka hopena Chain o nā radical manuahi (e nānā i ka Free Radical Reaction).I ka manawa like, hiki ke hoʻohui pū ʻia me ʻelua mau molekala e Chemicalbook e hana i ka tetramethyl Succinonitrile (TMSN) me ka ʻawaʻawa ikaika.I ka hoʻomehana ʻana iā AIBN i ka 100-107 ° C, hoʻoheheʻe ʻo ia a hoʻoheheʻe wikiwiki ʻia, e hoʻokuʻu ana i ke kinoea nitrogen a me nā pūhui nitrile meaʻawaʻawa, hiki ke hoʻoulu a pahū.E hoʻoheheʻe mālie i ka lumi wela a mālama i lalo o 10 ° C. E mālama i nā huna ahi a me nā kumu wela.ʻona.Hoʻopili ʻia i loko o ka waikawa hydrocyanic i loko o nā ʻiʻo holoholona e like me ke koko, ate, a me ka lolo.

6.Storage a me ka halihali ano:

① Hoʻokaʻawale ʻana i nā mea ʻawaʻawa: Poisoning

② ʻO nā hiʻohiʻona pōʻino pahū: hiki ke pahū ke hui pū ʻia me nā mea ʻona;E maʻalahi ke hoʻoheheʻe ʻia, paʻa ʻole, hoʻoheheʻe ikaika ʻia ma lalo o ka wela, a pahū ka Chemicalbook i ka wā i wela ai me ka heptane a me ka acetone.

③ Nā hiʻohiʻona pōʻino hiki ke hoʻā ʻia: ʻAi ʻia i ke alo o ke ahi hāmama, nā wela kiʻekiʻe, a me nā mea hoʻoheheʻe;Hoʻoheheʻe i nā kinoea hiki ke hoʻā ʻia ke ʻike ʻia i ka wela;Hoʻopuka ka puhi ʻana i ka uahi nitrogen oxide ʻona

④ ʻO nā hiʻohiʻona mālama a me ka lawe ʻana: ka ea hale kūʻai, ka maloʻo haʻahaʻa haʻahaʻa;E kūʻai kaʻawale mai nā oxidants

⑤ Mea hoʻopau: wai, one maloʻo, carbon dioxide, huʻa, 1211 mea kinai.
