Ruzivo nezve AIBN (CAS:78-67-1)

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

2.Hunhu hwemakemikari:

Makristasi machena ekoramu kana makristasi machena akaita seupfu. Haanyungudike mumvura, anonyungudika muzvinhu zvinonyungudutsa zvakaita semethanol, ethanol, acetone, ether, Petroleum ether uye aniline.

3. Chinangwa:

Senzira yekutanga polymerization yevinyl chloride, Vinyl acetate, acrylonitrile nedzimwe monomers, pamwe chete nefuro rinoita kuti rabha nemapurasitiki zvivepo, chiyero chacho chiri 10% ~ 20%. Chigadzirwa ichi chinogona kushandiswawo se vulcanizing agent, agricultural chemicalbook medicine, uye intermediate in organic synthesis. Chigadzirwa ichi chinhu chine chepfu yakawanda. Oral LD5017.2-25mg/kg mumakonzo inogona kukonzera chepfu yakakura kuvanhu nekuda kwekuburitswa kwe organic cyanide panguva yekuora kwekupisa.

4. Nzira yekugadzira:

Acetone, hydrazine hydrate uye Sodium cyanide zvinoshandiswa sezvinhu zvakabikwa: tembiricha yeCondensation reaction iri pamusoro apa ndeye 55~60 ℃, nguva yereaction ndeye 5h, uye yozotonhorera kusvika 25~30 ℃ kwemaawa maviri. Kana tembiricha yadzikira kusvika pasi pe10 ℃, chlorine inounzwa uye reaction inoitika pasi pe20 ℃ muChemicalbook. Chiyero chezvinhu izvi ndeichi: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg. Acetone cyanohydrin inopindirana nehydrazine hydrate, yozosanganiswa ne liquid chlorine kana aminobutyronitrile neSodium hypochlorite.

5. Kupisa kwekutanga kwemutangi

AIBN iRadical initiator yakanaka kwazvo. Kana yapiswa kusvika pa70°C, inoora yoburitsa nitrogen yogadzira free radical (CH3) 2CCN. Free radical inogadzikana nekuda kwesimba re cyano group. Inogona kuita chimwe chinhu che organic substrate yozodzoka kuita free radical itsva uku ichizviparadza, nokudaro ichikonzera Chain reaction ye free radicals (ona Free Radical Reaction). Panguva imwe chete, inogonawo kubatanidzwa nemamorekuru maviri neChemicalbook kugadzira tetramethyl Succinonitrile (TMSN) ine chepfu yakasimba. Painodziya AIBN kusvika pa100-107°C, inonyunguduka uye inoora nekukurumidza, ichiburitsa nitrogen gasi uye akawanda ma organic nitrile compounds ane chepfu, izvo zvinogonawo kukonzera kuputika uye kupisa. Inoora zvishoma nezvishoma patembiricha yemumba uye chengeta pasi pe10°C. Chengeta kure nemasparks uye manyuko ekupisa. Ine chepfu. Inogayiwa kuita hydrocyanic acid munyama dzemhuka dzakadai seropa, chiropa, neuropi.

6. Hunhu hwekuchengetedza uye hwekufambisa:

① Kupatsanura chepfu: Chepfu

② Hunhu hwenjodzi inoputika: inogona kuputika kana yakasanganiswa ne oxidants; Zviri nyore kuoxidation, kusagadzikana, inoora zvakasimba kana ichipisa, uye inoputika Chemicalbook kana yapiswa ne heptane ne acetone

③ Hunhu hwenjodzi yekubatidzwa: Hunobatidzwa kana paine moto wakavhurika, tembiricha yakakwira, uye zvinhu zvinooxidating; Hunoora magasi anobatidzwa kana apiswa; Kupisa kunoburitsa utsi hune chepfu hwenitrogen oxide

④ Hunhu hwekuchengetedza nekutakura: kufefetera kwemudura, kuomesa pakupisa kushoma; Chengeta zvakasiyana nezvinokonzera oxidants

⑤ Chinhu chinodzima moto: mvura, jecha rakaoma, kabhoni dhayiokisaidhi, furo, chinhu chinodzima moto che1211
