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 organik e like me ka methanol, ethanol, acetone, ether, Petroleum ether a me ka aniline.

3.Pahuhopu:

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

4. Ke ʻano hana:

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

5. Ka mahana hoʻomaka o ka mea hoʻomaka

He mea hoʻomaka Radical maikaʻi loa ʻo AIBN. Ke hoʻomehana ʻia a hiki i kahi o 70 ° C, e palaho a hoʻokuʻu i ka naikokene a hana i ka radical manuahi (CH3) 2CCN. He paʻa iki ka radical manuahi ma muli o ka mana o ka hui cyano. Hiki iā ia ke hana me kahi substrate organik ʻē aʻe a hana hou i loko o kahi radical manuahi hou me ka luku ʻana iā ia iho, a laila e hoʻoulu ai i ka Chain reaction o nā radical manuahi (e ʻike i ka Free Radical Reaction). I ka manawa like, hiki ke hoʻopili ʻia me ʻelua mau molekala e Chemicalbook e hana i ka tetramethyl Succinonitrile (TMSN) me ka ʻawaʻawa ikaika. Ke hoʻomehana ʻia ka AIBN i 100-107 ° C, heheʻe ia a hele i ka palaho wikiwiki, e hoʻokuʻu ana i ke kinoea naikokene a me kekahi mau hui nitrile organik ʻawaʻawa, hiki ke hoʻoulu i ka pahū a me ke ahi. Palaho mālie i ka mahana o ka lumi a mālama ma lalo o 10 ° C. E mālama mamao mai nā huna ahi a me nā kumu wela. ʻAwaʻawa. Hoʻololi ʻia i loko o ka waikawa hydrocyanic i loko o nā ʻiʻo holoholona e like me ke koko, ke akepaʻa, a me ka lolo.

6. Nā ʻano mālama a me ka halihali:

① Hoʻokaʻawale ʻona: ʻAi ʻona

② Nā ʻano pōʻino pahū: hiki ke pahū ke hui pū ʻia me nā mea hoʻomake; Maʻalahi e hoʻomake, paʻa ʻole, palaho ikaika ma lalo o ka wela, a pahū i ka wā e hoʻomehana ʻia ai me ka heptane a me ka acetone

③ Nā ʻano pōpilikia lapalapa: Hiki ke lapalapa i ke alo o nā lapalapa ahi, nā mahana kiʻekiʻe, a me nā mea hoʻoheheʻe oxidizing; Hoʻopau i nā kinoea lapalapa i ka wā e hōʻike ʻia ai i ka wela; Hoʻopuka ka puhi ʻana i ka uahi nitrogen oxide ʻawahia

④ Nā ʻano mālama a me ka halihali: ea hale kūʻai, hoʻomaloʻo haʻahaʻa; E mālama kaʻawale mai nā mea hoʻomake

⑤ Mea kinai ahi: wai, one maloʻo, kalapona ʻokikene, huʻa, 1211 mea kinai ahi
