Methanol thiab acetonitrile yog cov organic acids uas feem ntau siv los ua lub sijhawm txawb hauv thim rov qab -theem chromatography. Tab sis, CAS 75-05-8 acetonitrile (ACN) feem ntau suav hais tias yog ib qho hnyav dua Methanol (MeOH).
Puas yog Acetonitrile Acn (CAS 75-05-8) muaj zog hnyav dua methanol (CAS 67-56-1)?
Hauv HPLC (Rov qab-Phase): Acetonitrile yog qhov muaj zog dua li methanol. Nws muaj txiaj ntsig zoo dua tshem cov tshuaj ntsuam xyuas los ntawm kab C18. Yuav kom tau txais tib lub sijhawm khaws cia, koj xav tau ACN tsawg dua hauv dej dua methanol. ACN kuj tseem muaj cov viscosity qis dua thiab ua kom muaj kev rov qab qis dua, tso cai rau kev khiav nrawm dua thiab ua haujlwm ntau dua.
Raws li General Solvent / Polarity: Acetonitrile yog ntau dua polar dua methanol. Methanol tuaj yeem koom nrog kev sib koom ua ke ntawm hydrogen muaj zog, uas acetonitrile tsis tuaj yeem. Yog li methanol feem ntau yog cov kuab tshuaj zoo dua rau cov polar, hydrogen- cov khoom sib txuas xws li phenols lossis carboxylic acids.
Rau Dissolving Fais Fab: "Ntau zog" tsis yog kiag li. Methanol yog zoo dua rau dissolving polar, protic cov ntaub ntawv. Acetonitrile yog qhov zoo dua rau kev sib cais ntau yam sib xyaw thiab cov ntsev, thiab yog qhov zoo tshaj qhov uas tsis muaj - cuam tshuam, tsis yog - hydrogen - cov kuab tshuaj sib txuas.
