1.Hmong npe:2,2'-azobis (2-methylpropionitrile)
2.Tshuaj Tshuaj Muaj Zog:
Dawb Colorar muaju lossis cov hmoov dawb powdaly. Insoluble hauv dej, soluble hauv cov kuab tshuaj organic xws li Methanol, ethanol, acetone, etherum etherip ether thiab Aniline.
3.pov:
Raws li qhov pib rau polymerization ntawm vinyl chloride, acryloniturile thiab lwm tus neeg monomers, nrog rau cov roj hmab thiab lwm yam kev siv roj hmab yog 10% ~ 20%. Cov khoom no tseem tuaj yeem siv los ua cov tshuaj vulcanizing, cov tshuaj kho kom zoo nkauj siv tshuaj, thiab nruab nrab hauv nruab nrab ntawm cov etthic. Cov khoom no yog cov tshuaj lom neeg. Qhov ncauj LD5017.2-25mg / kg hauv cov nas tuaj yeem ua rau tib neeg muaj kev lom zem rau cov organic cyanide thaum lub thermal decomposition.
Txoj kev:
Acetone, hydrazine hydrate thiab sodium cyanide siv tau cov khoom raw: cov kev sib tw ua kom sov saum toj no yog 5h, thiab tom qab ntawd txias rau 25 ~ 30 ℃ rau 2H. Thaum qhov kub thiab txias rau hauv qab 10 ℃, chlorine tau qhia thiab cov tshuaj tiv thaiv yuav siv qhov chaw qis dua 20 ℃ hauv kev siv tshuaj. Cov khoom sib piv yog: HCN: Acetone: Hydrazine = 1L: 1.5036KG: 0.415kg. Acetone CyanoYdrin reacts nrog hydrazine hydrate, thiab tom qab ntawd oxidizes nrog cov tshuaj yeeb yaj kiab lossis aminobutyronitrile.
5.Txoj ke kub ntawm tus pib
AIBN yog ib qho tshwj xeeb tshaj yog radical pib. Thaum rhuab txog li 70 ° C, nws yuav decompose thiab tso cov nitrogen thiab tsim kom muaj pub dawb radical (ch3) 2cn. Tus dawb radical yog qhov sib luag yog vim hais tias muaj kev cuam tshuam ntawm Cyano Group. Nws tuaj yeem cuam tshuam nrog lwm organic substrate thiab tsim tawm mus rau qhov tshiab radical thaum rhuav tshem nws tus kheej, yog li ua rau radicals dawb (saib dawb radicals). Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem sib txuas nrog ob lub lwg me me los ntawm cov tshuaj lom neeg los tsim tetramethylcinonitrile (tmsn) nrog muaj kuab lom (TMSN) nrog muaj zog toxicity. Thaum cua sov AIBN rau 100-107 ° C, nws melts thiab undergoes sai decomposition, tso cov tshuaj lom organic thiab ntau yam lom nitrile nitrile tebchaw, uas tej zaum yuav ua rau tawg thiab ignition. Maj mam decompose nyob rau hauv chav tsev kub thiab khw hauv qab 10 ° C. kom deb ntawm cov txim taws thiab cov khoom kub. Lom. Metabolized rau hauv hydrocyanic acid nyob rau hauv cov nqaij tsiaj xws li ntshav, nplooj siab, thiab lub hlwb.
6.Txhua thiab cov yam ntxwv thauj mus los:
① Kev Ntsuas Kev Ntsuas Tshwj Xeeb: Tshuaj lom
Cov neeg muaj kev phom sij: tuaj yeem tawg thaum sib xyaw ua ke nrog oxidants; Yooj yim rau oxidize, tsis ruaj khov, muaj zog decomposes nyob rau hauv tshav kub, thiab tawg tshuaj lom neeg thaum rhuab nrog heptane thiab acetone
③ Flammability cov yam ntxwv tsis zoo: flammable nyob rau hauv lub xub ntiag ntawm qhib cov nplaim taws, kev kub siab, thiab oxidizing cov neeg sawv cev; Decomposes flams gases thaum raug cua sov; Kev hlawv cov pa luam yeeb nitrogen oxide
④ cia thiab tsheb thauj mus los: Warehouse cua, tsawg-kub qhuav; Khaws cais los ntawm oxidants
⑤ Extinguishing tus neeg saib xyuas: dej, qhuav xuab zeb, carbon dioxide, ua npuas ncauj, 1211 extinguishishing tus neeg sawv cev
