CAS 75-05-8 Acetonitrile - Siv
1. Cov kuab tshuaj:Acetonitrile yog dav siv los ua ib qho hnyav hauv tshuaj syntheses, extractions, thiab purifications. Nws yog tshwj xeeb tshaj yog pab tau rau dissolving polar tebchaw thiab muaj ib tug siab hnyav zog rau ntau cov organic tebchaw.
2. Chromatography: ACNfeem ntau yog siv los ua eluent (theem mobile) hauv chromatography, cov txheej txheem siv los cais thiab ntxuav cov tshuaj sib tov. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv siab -kev ua haujlwm ua kua chromatography (HPLC) thiab roj chromatography (GC).
3. Reagent: Acetonitrile / methyl cyanide yog siv los ua cov tshuaj reagent hauv kev sib txuas ntawm ntau yam tshuaj, suav nrog tshuaj, tshuaj pleev xim, thiab cov yas.
4. Analytical chemistry:Nws yog siv nyob rau hauv ntau yam analytical chemistry hom kev kawm, xws li nuclear magnetic resonance (NMR) spectroscopy, infrared (IR) spectroscopy, thiab huab hwm coj spectrometry (MS).
5. Kev ntxuav:CAS 75-05-8 Acetonitrile tuaj yeem siv los ntxuav thiab degrease qhov chaw thiab khoom siv hauv ntau qhov chaw tsim khoom.
6. Kev tsim tshuaj tua kab:Nws yog siv nyob rau hauv zus tau tej cov tshuaj tua kab.
7. Extracting roj:Acetonitrile hnyav yog siv rau hauv kev rho tawm cov roj los ntawm shale thiab lwm qhov chaw.
