cov ntaub ntawv
5-CYANO-1-PENTYNE (CAS # 14918-21-9)
xwm
Acetylene nitrile tau tsim. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw. Cov hauv qab no yog qee qhov tseem ceeb ntawm acetylenic nitriles:
1. Solubility: Nitrile muaj cov dej solubility tsawg, tab sis tuaj yeem yaj hauv qee cov kuab tshuaj organic xws li cawv, ethers, ketones, chlorinated hydrocarbons, thiab lwm yam.
2. Stability: Nitrile kuj ruaj khov nyob rau hauv chav tsev kub, tab sis nws undergoes polymerization cov tshuaj tiv thaiv thaum rhuab. Nws tuaj yeem cuam tshuam nrog cov tshuaj nrog cov pab pawg ua haujlwm, xws li cawv, kua qaub, thiab lwm yam, los tsim cov tshuaj sib txawv.
3. Toxicity: Nitrile muaj qee yam toxicity thiab tuaj yeem ua rau tawv nqaij thiab mucous daim nyias nyias. Lub sij hawm ntev los yog kev noj ntau dhau ntawm acetylenic nitriles tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
4. Cov tshuaj tiv thaiv tshuaj: Acetylene nitrile tuaj yeem ua rau cov tshuaj tiv thaiv ntxiv, cov tshuaj tiv thaiv hydrogenation, electron ntxiv cov tshuaj tiv thaiv, thiab lwm yam. Feem ntau siv rau kev sib txuas cov organic tseem ceeb xws li ketones, esters, thiab lwm yam.
kev ruaj ntseg cov ntaub ntawv
Nitrile (tseem hu ua acetylene wax) yog tshuaj lom neeg. Hauv qab no yog cov ntaub ntawv kev nyab xeeb txog acetylene nitrile:
1. Toxicity: Nitrile yog ib yam tshuaj lom neeg uas tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev nqus pa, sib cuag ntawm daim tawv nqaij, thiab noj. Nws yog irritating thiab corrosive, thiab tej zaum yuav ua rau puas tsuaj rau daim tawv nqaij, qhov muag, ua pa system, thiab digestive system.
2. Kev sib cuag ntawm daim tawv nqaij: Nitrile tuaj yeem ua rau tawv nqaij khaus thiab ua xua.
3. Kev sib cuag qhov muag: raug acetylene tuaj yeem ua rau qhov muag khaus thiab puas. Yog tias muaj kev sib cuag, tam sim ntawd yaug qhov muag nrog dej kom ntau li 15 feeb thiab nrhiav kev kho mob tam sim ntawd.
4. Cov teebmeem ntawm kev ua pa: Kev nqus pa ntawm acetylene tuaj yeem ua rau ua pa ua pa, mob caj pas, hnoos, ua pa nyuaj, thiab hauv siab nruj.
5. Kev pab cuam thawj zaug: Thaum nqus tau, sib chwv ntawm daim tawv nqaij, lossis qhov muag pom nrog acetylene nitrile, yuav tsum tau muab kev pab thawj zaug tam sim ntawd thiab yuav tsum tau nrhiav kev kho mob tam sim ntawd.
6. Cia thiab tuav: Nitrile yuav tsum muab cia rau hauv qhov tsaus ntuj, kaw, thiab qhov cua zoo. Nws yuav tsum tau muab cais los ntawm oxidants thiab muaj zog acids. Thaum tuav acetylene nitrile, yuav tsum hnav cov khoom tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.
