Acetonitrile (CAS 75-05-8) Kev Nyab Xeeb thiab Kev Nyab Xeeb Kev Nyab Xeeb
Acetonitrile (CAS 75-05-8) yog ib qho kev siv tshuaj hnyav heev, tab sis zoo li ntau cov organic nitriles, nws nthuav qhia txog kev noj qab haus huv thiab kev nyab xeeb yog tias tsis ua haujlwm zoo. Kev nkag siab txog nws cov toxicological profile thiab kev cia khoom yog qhov tseem ceeb rau kev nyab xeeb kev lag luam thiab kev sim siv.
Kev Nyab Xeeb Kev Nyab Xeeb ntawm Acetonitrile
Acetonitrile nthuav tawm mob toxicity nruab nrab. Thaum lub sij hawm luv luv - raug rau cov khoom me me tuaj yeem ua rau tsuas yog cov tsos mob me me xwb, kev raug mob ntau dua ua rau muaj kev pheej hmoo loj dua. Thaum absorbed rau hauv lub cev, acetonitrile tuaj yeem metabolized rau hauv hydrogen cyanide, ib qho tshuaj lom heev. Cov txheej txheem metabolic no tshwm sim maj mam, uas txhais tau hais tias cov tsos mob yuav qeeb dua li tam sim.
Feem ntau luv luv- cov teebmeem tshwm sim muaj xws li khaus ntawm qhov muag, qhov ntswg, caj pas, thiab ua pa. Kev raug mob ntev lossis rov ua dua tau cuam tshuam nrog kev txhawj xeeb txog kev noj qab haus huv ntau dua, xws li:
- Mob taub hau thiab kiv taub hau
- Kev qaug zog thiab cov leeg tsis muaj zog
- loog los yog tingling hnov
- Poob qab los noj mov
- Ntshai
Ntev -ntev ntev yuav ua rau muaj kev cuam tshuam rau cov kabmob loj, nrog rau lub siab, lub ntsws, lub raum, thiab lub hauv nruab nrab lub paj hlwb. Cov kev tshawb fawb tsiaj kuj tau qhia txog qhov muaj peev xwm ua rau muaj menyuam, xws li txo qhov yug menyuam thiab kev loj hlob txawv txav, qhia txog qhov yuav tsum tau muaj kev tswj xyuas nruj heev.
Acetonitrile (CAS 75-05-8) Kev Cia Siab
Kev khaws cia kom zoo yog qhov tseem ceeb rau kev txo qis hluav taws, tawg, thiab kev noj qab haus huv cuam tshuam nrog acetonitrile.
Pom zoo cia tej yam kev mob
Cov tshuaj acetonitrileyuav tsum tau muab khaws cia rau hauv qhov chaw kaw, corrosion-cov thawv uas tsis muaj zog thiab khaws cia kom deb ntawm qhov chaw sov, cov nplaim taws, thiab cov nplaim taws qhib. Cov chaw khaws cia yuav tsum txias, qhuav, thiab zoo -ventilated los tiv thaiv vapor tsub zuj zuj.
Txhawm rau kom tsis txhob muaj tshuaj lom neeg txaus ntshai, acetonitrile yuav tsum raug cais tawm ntawm cov khoom siv tsis sib xws, suav nrog:
- Muaj zog oxidizing tus neeg sawv cev
- Muaj zog acids
- Txo cov neeg ua haujlwm
- Alkaline tshuaj (bases)
Kev tshuaj xyuas niaj hnub yuav tsum tau ua txhawm rau txheeb xyuas cov dej xau, ntim khoom puas, lossis cov khoom siv degradation, ua kom ruaj ntseg ntev -.
Kev Tswj Xyuas Qhov Zoo Tshaj Plaws
Txhawm rau txhim kho kev nyab xeeb thiab kev tswj hwm kev pheej hmoo, cov chaw tuav acetonitrile yuav tsum ua raws li cov kev ntsuas hauv qab no:
- Lub sijhawm tshuaj xyuas thiab hloov kho cov txheej txheem khaws cia
- Kom meej meej sau cov thawv ntim thiab cov chaw cia khoom xaiv
- Muab kev cob qhia kom zoo rau txhua tus neeg ua haujlwm nrog kev nkag mus rau thaj chaw khaws cia
- Khaws cov khoom lag luam kom raug thiab cov ntaub ntawv qhov chaw
Teb rau Acetonitrile Spills thiab Leaks
Nyob rau hauv cov xwm txheej ntawm acetonitrile spill los yog to, yuav tsum tau khiav tawm tam sim ntawd ntawm qhov chaw cuam tshuam. Vim tias acetonitrile yog cov nplaim hluav taws kub heev, txhua qhov hluav taws kub yuav tsum raug tshem tawm yam tsis muaj kev ncua.
Xyuas kom muaj qhov cua txaus kom tawg tawm cov vapors thiab txo qis kev nqus pa. Cov khoom nchuav yuav tsum tau ntim nrog cov khoom siv inert, absorbent, thiab kev ntxuav tu yuav tsum tau ua nrog cov pa taws - cov cuab yeej pov thawj nkaus xwb los tiv thaiv kev sib tsoo.
Kev lag luam siv Acetonitrile
