Acetonitrile (CAS 75-05-8) Cov khoom
Acetonitrile, nrog rau cov tshuaj formula CH₃CN, yog cov xim tsis muaj xim, pob tshab kua hnyav. Nws pom muaj zog polarity thiab soluble hauv dej thiab ntau cov kuab tshuaj organic xws li ethanol thiab chloroform. Nws qhov kub qis qis ntawm 81℃yooj yim distillation thiab rov qab los. Acetonitrile kuj muaj qhov ruaj khov zoo, ua rau nws nquag siv los ua cov tshuaj tiv thaiv hnyav.
Acetonitrile (CAS 75-05-8) Lub cev muaj zog thiab kev siv
Acetonitrile muaj cov ntsiab lus boiling tsawg thiab melting, tshuav kua nyob rau hauv chav tsev kub. Nws kuj ua hauj lwm raws li ib tug zoo heev hnyav muaj peev xwm ntawm dissolving ntau yam organic tebchaw thiab inorganic ntsev. Yog li ntawd, acetonitrile pom kev siv dav hauv kev lag luam tshuaj rau cov khoom siv hluavtaws, hluavtaws roj hmab, tshuaj, tshuaj tua kab, tshuaj pleev xim, thiab lwm yam. Tsis tas li ntawd, acetonitrile yog ib qho extractant, tshuaj tiv thaiv nruab nrab, thiab hnyav hauv chromatographic tsom xam.
Acetonitrile Disadvantages
Acetonitrile yog ib qho uas nquag siv cov kuab tshuaj organic, tab sis nws txoj kev siv thiab kev tuav pov hwm muaj ob peb qhov teeb meem tseem ceeb thiab muaj kev phom sij rau kev noj qab haus huv, feem ntau suav nrog cov hauv qab no:
- Toxicity: Acetonitrile yog tshuaj lom heev. Kev nqus pa ntawm nws cov vapors lossis kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau mob hnyav heev. Nws cov metabolism hauv lub cev tso tawm cyanide ions, uas cuam tshuam nrog cellular respiration thiab ua rau cov ntaub so ntswg hypoxia. Cov tsos mob muaj xws li kiv taub hau, mob taub hau, xeev siab, ntuav, thiab tsis nco qab. Cov mob hnyav tuaj yeem ua rau coma, ua pa tsis ua haujlwm, lossis tuag.
- Flammability thiab Safety Risks : Acetonitrile yog cov kua ua kua uas nws cov vapors tuaj yeem tsim cov khoom tawg nrog cua. Cov nplaim taws qhib, kub kub, lossis kev sib cuag nrog cov oxidizers ua rau muaj kev pheej hmoo ntawm kev tawg lossis tawg.
- Environmental and Handling Risks: Acetonitrile leaks nkag mus rau hauv cov kav dej los yog ib puag ncig ntuj yuav ua rau muaj kab mob. Nws combustion lossis decomposition ua rau cov pa roj carbon monoxide, carbon dioxide, nitrogen oxides, thiab hydrogen cyanide, ua rau muaj kev hem thawj rau ib puag ncig thiab cov neeg muaj xwm txheej ceev.
Dab tsi ntawm cov kuab tshuaj yog ACN?
Acetonitrile los yog methyl cyanide yog ib qho muaj zog heev, aprotic polar organic hnyav.
Acetonitrile (CAS 75-05-8), raws li ib tug polar organic solvent, muaj ntau daim ntawv thov. Hauv qab no yog ob peb qhov chaw siv ntau yam:
Tshuaj Synthesis
Acetonitrile ua haujlwm raws li cov kuab tshuaj thiab lub cev qhuav dej hauv ntau cov organic synthesis tshwm sim.
Pharmaceuticals
Acetonitrile yog cov kuab tshuaj siv dav hauv kev lag luam tshuaj, ua haujlwm hauv kev tsim tshuaj tua kab mob, tshuaj hormones, vitamins, tshuaj intermediates, thiab lwm yam.
Kev kho mob hlau
Thaum lub sij hawm ua cov hlau nto, acetonitrile cov ntaub ntawv complexes nrog impurity ions nyob rau hauv cov hlau, yooj yim tshem tawm cov kab mob thiab cov pa phem.
Lwm Daim Ntawv Thov
Acetonitrile kuj tseem ua cov kuab tshuaj lossis cov tshuaj tiv thaiv nruab nrab rau dyes, coatings, plastics, rubber, textiles, thiab ntau dua. Tsis tas li ntawd, nws yog siv rau cov qauv pretreatment hauv kev ntsuas ntsuas xws li roj chromatography, NMR, thiab infrared spectroscopy.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
Qhov zoo
1) Cov khoom xa tuaj me me thiab sub- ntim khoom muaj.
2). Muab COA, MSDS, Daim Ntawv Pov Thawj Kev Noj Qab Haus Huv, thiab Daim Ntawv Pov Thawj Keeb Kwm.
3) Zoo ua ntej, kev pabcuam zoo tshaj plaws.
Nyem qhov no kom tau txais qhov tseeb thoob ntiaj tebAcetonitrile (CAS 75-05-8) cov nqi lag luam rau xyoo 2026.
