Imwe ruzivo nezve AIBN (CAS:78-67-1)

1.Zita rechirungu:2,2′-Azobis(2-methylpropionitrile)

2.Chemical properties:

White columnar crystals kana white powdery crystals.Isinganyunguriki mumvura, inonyungudika muorganic solvents senge methanol, ethanol, acetone, ether, Petroleum ether uye aniline.

3. Chinangwa:

Semunhu wekutanga wepolymerization yevinyl chloride, Vinyl acetate, acrylonitrile uye mamwe mamonomers, pamwe neanogadzira furo rerabha nemapurasitiki, muyero wacho i10% ~ 20%.Ichi chigadzirwa chinogona zvakare kushandiswa seanokuvadza mumiriri, mushonga wezvekurima wemakemikaribook, uye wepakati mune organic synthesis.Ichi chigadzirwa chinhu chine chepfu zvakanyanya.Oral LD5017.2-25mg/kg mumakonzo inogona kukonzera huturu hwakakosha kuvanhu nekuda kwekuburitswa kwe organic cyanide panguva yekupisa kwekupisa.

4.Kugadzira nzira:

Acetone, hydrazine hydrate uye Sodium cyanide inoshandiswa seyakagadzirwa: iyo iri pamusoro Condensation reaction tembiricha i55 ~ 60 ℃, nguva yekupindura ndeye 5h, uyezve kutonhora kusvika 25 ~ 30 ℃ kwe2h.Kana tembiricha yadonha kusvika pasi pe10 ℃, chlorine inounzwa uye maitiro anoitika pazasi 20 ℃ mu Chemicalbook.The material reshiyo ndeiyi: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg.Acetone cyanohydrin inopindirana ne hydrazine hydrate, uyezve oxidize ne liquid chlorine kana aminobutyronitrile neSodium hypochlorite.

5.Kutanga kupisa kwekutanga

AIBN inonyanya kunaka Radical initiator.Kana yapisa kusvika pa70 ° C, inoora uye kuburitsa nitrogen uye kugadzira mahara radical (CH3) 2CCN.Iyo yemahara radical yakagadzikana nekuda kwesimba reboka recyano.Inogona kuita neimwe organic substrate uye kuvandudzwa kuita itsva yemahara radical ichizvitsakatisa, nekudaro ichikonzeresa kuita kweChain yemahara radicals (ona Mahara Radical Reaction).Panguva imwecheteyo, inogona zvakare kusanganiswa nemamorekuru maviri ne Chemicalbook kugadzira tetramethyl Succinonitrile (TMSN) ine muchetura wakasimba.Kana ichipisa AIBN kusvika 100-107 ° C, inonyunguduka uye inokurumidza kuora, ichiburitsa gasi renitrogen uye akati wandei ane muchetura organic nitrile makomponi, ayo anogona kukonzera kuputika nekubatidza.Zvishoma nezvishoma kuora mukamuri yekupisa uye chengetedza pasi pe10 ° C. Ramba kure nepfari uye zvinopisa.Toxic.Metabolized kuita hydrocyanic acid mumhuka mhuka dzakadai seropa, chiropa, uye uropi.

6.Kuchengetedza uye maitiro ekufambisa:

① Chepfu kupatsanurwa: Chepfu

② Kuputika kwengozi maitiro: inogona kuputika kana yakasanganiswa neoxidants;Nyore kuokisisa, kusagadzikana, kunyura zvakanyanya mukupisa, uye inoputika Chemicalbook kana yapiswa neheptane uye acetone.

③ Hunhu hwengozi yekupisa: Kupisa pamberi pemirazvo yakavhurika, tembiricha yepamusoro, uye oxidizing agents;Inoora magasi anopfuta kana akaiswa pakupisa;Kupisa kunoburitsa muchetura wenitrogen oxide

④ Kuchengetedza uye hunhu hwekufambisa: mhepo yekuchengetera mhepo, yakaderera-yekushisa kuomesa;Chengetedza zvakasiyana kubva kune oxidants

⑤ Kudzimisa mumiriri: mvura, jecha rakaoma, kabhoni dhaikisaidhi, furo, 1211 inodzima mumiriri.
