1.Igama lesiNgisi:2,2′-Azobis(2-methylpropionitrile)
2.Izakhiwo zamakhemikhali:
Amakristalu amhlophe acwebezelayo noma amakristalu amhlophe anombala ompuphu. Angancibiliki emanzini, ancibilika ezinyibilikisini eziphilayo ezifana ne-methanol, i-ethanol, i-acetone, i-ether, i-Petroleum ether kanye ne-aniline.
3. Inhloso:
Njengomqalisi we-polymerization ye-vinyl chloride, i-vinyl acetate, i-acrylonitrile namanye ama-monomers, kanye ne-ejenti ye-foam yerabha nepulasitiki, umthamo u-10% ~ 20%. Lo mkhiqizo ungasetshenziswa futhi njenge-ejenti ye-vulcanizing, umuthi we-agricultural chemicalbook, kanye ne-intermediate in organic synthesis. Lo mkhiqizo uyinto enobuthi kakhulu. I-LD5017.2-25mg/kg yomlomo kumagundane ingadala ubuthi obukhulu kubantu ngenxa yokukhishwa kwe-cyanide ephilayo ngesikhathi sokubola kokushisa.
4. Indlela yokukhiqiza:
I-Acetone, i-hydrazine hydrate kanye ne-Sodium cyanide kusetshenziswa njengezinto zokusetshenziswa: izinga lokushisa lokusabela kwe-Condensation elingenhla lingu-55~60 ℃, isikhathi sokusabela singamahora ama-5, bese kubanda kufike ku-25~30 ℃ amahora ama-2. Lapho izinga lokushisa lehla liye ngaphansi kuka-10 ℃, i-chlorine ifakwa futhi ukusabela kwenzeka ngaphansi kuka-20 ℃ ku-Chemicalbook. Isilinganiso sezinto ezibonakalayo yilesi: HCN: i-acetone: i-hydrazine=1L: 1.5036kg: 0.415kg. I-Acetone cyanohydrin isabela ne-hydrazine hydrate, bese ixubana ne-chlorine ewuketshezi noma i-aminobutyronitrile ne-Sodium hypochlorite.
5. Izinga lokushisa lokuqalisa lomsunguli
I-AIBN iyisiqalisi se-Radical esihle kakhulu. Uma ishiswa cishe ku-70 ° C, izobola futhi ikhiphe i-nitrogen futhi ikhiqize i-free radical (CH3) 2CCN. I-free radical izinzile ngenxa yethonya leqembu le-cyano. Ingasabela nenye i-substrate ephilayo futhi iphinde ikhule ibe yi-free radical entsha ngenkathi izibhubhisa, ngaleyo ndlela ibangele ukusabela kwe-Chain yama-free radicals (bheka i-Free Radical Reaction). Ngesikhathi esifanayo, ingahlanganiswa nama-molecule amabili yi-Chemicalbook ukukhiqiza i-tetramethyl Succinonitrile (TMSN) enobuthi obunamandla. Uma ishiswa i-AIBN ku-100-107 ° C, iyancibilika futhi ibole ngokushesha, ikhiphe igesi ye-nitrogen kanye namakhemikhali amaningana anobuthi e-organic nitrile, angabangela nokuqhuma nokushisa. Ibola kancane kancane ekushiseni kwegumbi bese igcina ngaphansi kuka-10 ° C. Gcina kude nezinhlansi nemithombo yokushisa. Inobuthi. Iguqulwa ibe yi-hydrocyanic acid ezicutshini zezilwane njengegazi, isibindi, nobuchopho.
6. Izici zokugcina nezokuthutha:
① Ukuhlukaniswa kobuthi: Ubuthi
② Izici zengozi yokuqhuma: ingaqhuma uma ixutshwe nama-oxidants; Kulula ukuyixuba, ayizinzile, ibola kakhulu uma ishiswa, futhi iqhume. I-Chemicalbook uma ishiswa nge-heptane ne-acetone.
③ Izici zengozi yokusha: Iyasha uma kukhona amalangabi avulekile, amazinga okushisa aphezulu, kanye nezinto ezikhipha i-oxidizing; Ibolisa amagesi asha uma evezwa ekushiseni; Ukusha kukhiqiza umusi onobuthi we-nitrogen oxide
④ Izici zokugcina kanye nezokuthutha: umoya ongenisa impahla yokugcina, ukomisa ngokushisa okuphansi; Gcina ngokwehlukana nama-oxidants
⑤ I-ejenti yokucisha: amanzi, isihlabathi esomile, i-carbon dioxide, igwebu, i-ejenti yokucisha engu-1211
Isikhathi sokuthunyelwe: Juni-26-2023
