Rumwe Ruzivo nezve Aibn (CASA: 78-67-1)

1.Chirungu Zita:2,2-----azobis (2-methylpropionitrile)

2.Zvemakemikari zvivakwa:

Chena columnar makristasi kana chena powdery makristasi. Insoluble mumvura, soluble mu organic sol, ethanol, acetone, ether, petroleum ether uye anlin.

3.Purpose:

Semitambi yekutanga yePolymerization yeVinyl Chloride, Vinyl Acetate, Acryllonitrile uye mamwe masoja, pamwe neyekupumukira, iyo dosi iri 10% ~ 20%. Ichi chigadzirwa chinogona kushandiswawo seyakajaira mumiririri, okurima kemaribook mushonga, uye yepakati mu orghic synthesis. Ichi chigadzirwa chinhu chine chepfu chakanyanya. Oral LD5017.25mg / kg mumakonzo anogona kukonzera kukosha kwehupfu hwakakanganisika kuvanhu nekuda kwekuburitswa kweiyo organic cyanide panguva yekuora.

4.Protection Nzira:

Acetone, Hydrazine Hydrate uye Sodium Cyanide anoshandiswa seyakagadzirwa zvinhu: Iyo yepamusoro Conversation tembiricha ndeyekunyora kwe50 ~ Kana tembiricha ichidonha kusvika pazasi 10 ℃, chlorine inounzwa uye maitiro anoitika pazasi 20 ℃ muCemicalbook. Ratio iri: HCN: Acetone: Acetone: Hydrazine = 1l: 1.5036kg: 0.415kg. Acetone Cyanohydrin inoenderana neHydrazine hydrate, uyezve oxiddies ine mvura chlorine kana aminobutyronitrile ine sodium hypochlorite.

5Toiti (tembiricha yekudziya yetangetator

Aibn inonyanya kuve yakanakisa manyorati. Paakapomerwa kusvika pamakumi manomwe ° C, ichaita uye kuburitsa nitrogen uye gadzira yemahara radical (CH3) 2CCn. Iyo yemahara yakanyanya kugadzikana yakagadzikana nekuda kweiyo pesvedzero yeboka reCyano. Zvinogona kuita neimwe organtic substrate uye gadzirisa mune itsva yemahara nguva yekushambadzira pachavo, nekukonzera cheni yekuita kwemahara radicals (ona mahara maitiro ekusaita). Panguva imwecheteyo, inogona zvakare kubatanidzwa nemamolekyukiridzo maviri nemakemikari kugadzira Tetramethyl Paunenge uchishatisa ABN kusvika 100-107 ° C, inonyungudika uye inokurumidza kukurumidza kuora, kusunungura nitrogen gasi uye zvinoverengeka zvechisimba mishonga yejasi, iyo inogona kukonzera kuputika uye nekukonzera. Zvishoma nezvishoma kuora pamhepo tembiricha uye chengetedza pazasi 10 ° C. Ramba kure neSpark uye kupisa masisitiki. Chepfu. Metabolized mu hydrocyanic acid mumhuka yemhuka senge ropa, chiropa, uye uropi.

6.Storege uye maitiro ekufambisa:

① Kugadziriswa kweChidimbu: Upfu

② Kubiridzira Hazard Hunhu: Unogona Kuputika Kana Wakavhenganiswa neOkuti; Easy kune oxidize, isina kugadzikana, inokanganisa zvine simba pasi pekupisa, uye inoputika kemikari bhuku raipisa nehetane neacetone uye acetone

③ Kuwedzera njodzi hunhu: Inokanganisa magasi anopisa kana akaoneswa kupisa; Kupisa kunogadzira ine muchetura nitrogen oxide utsi

④ Kuchengetera uye maitiro ekufambisa: Warehouse mhepo, yakaderera-tembiricha kuoma; Chengetedza zvakasiyana kubva kune oxidants

⑤ Kuwedzera Mumiririri: Mvura, jecha rakaoma, kabhoni dioxide, foam, 1211 yekudzima mumiririri
