Acetonitrile yog ib qho hnyav me ntsis dua li methanol. Nws yog me ntsis ntxuav hauv UV; Koj tuaj yeem mus txog 190 nanometers nrog acetonitrile (piv rau 210 nanometers rau methanol). Acetonitrile muaj viscosity qis me ntsis, yog li ntawd yuav tsum muaj lub siab tsawg.
Vim li cas acetonitrile yog cov kuab tshuaj zoo?
Cov tshuaj acetonitrileyog xim tsis muaj xim, pob tshab organic hnyav nrog cov tshuaj formula CH₃CN. High-purity acetonitrile feem ntau muaj ntau dua 99.9% acetonitrile. Raws li cov kuab tshuaj polar, ACN nthuav tawm zoo heev solubility thiab muaj peev xwm yaj ntau cov organic thiab inorganic tebchaw, xws li fatty acids, aromatic thiab aliphatic tebchaw, thiab tsis muaj zog corrosive inorganic tshuaj.
Dab tsi yog cov yam ntxwv ntawm acetonitrile?
Acetonitrile (ACN) yog cov kuab tshuaj polar nrog cov tshuaj inertness zoo kawg nkaus; Txawm li cas los xij, nyob rau hauv tej yam kev mob, nws nkag mus rau electrophilic ntxiv los yog nucleophilic hloov cov tshuaj tiv thaiv. Tsis tas li ntawd, nws ua hauj lwm ua ib qho zoo heev hydrogen ion txais. Siab -purity acetonitrile muaj qhov kub ntawm 81.6 degree, qhov txheeb ze ntawm 0.786, thiab muaj nyob hauv cov kua hauv chav tsev kub. Nrog lub dielectric tas li ntawm 37.5, nws yog ib tug polar solvent uas yog insoluble nyob rau hauv ntau nonpolar organic solvents tab sis yooj yim soluble nyob rau hauv dej.
ACN siv rau dab tsi?
- Hauv kev tshawb fawb txog kev tshawb fawb, ACN ua haujlwm ua cov kuab tshuaj organic, cov tshuaj tiv thaiv nruab nrab, thiab cov extractant. Raws li qhov nruab nrab cov tshuaj tiv thaiv, nws pab txhawb cov txheej txheem tshuaj lom neeg xws li hloov pauv, oxidation, thiab ntxiv cov tshuaj tiv thaiv. High-purity acetonitrile kuj tseem ua haujlwm hauv siab -kev ua haujlwm ua kua chromatography (HPLC) rau kev sib cais thiab ntsuas cov khoom sib xyaw.
- Hauv kev tsim khoom lag luam, siab -purity acetonitrile ua haujlwm zoo sib xws. Nws ua haujlwm raws li cov khoom siv tseem ceeb rau kev tsim cov organic tebchaw thiab hluavtaws fibers (xws li, nylon). Tsis tas li ntawd, nws pom cov ntawv siv dav hauv electrochemistry, electroplating, foundry processes, synthetic rubber production, plastics manufacturing, and pharmaceuticals.
Hauv cov ntsiab lus, siab -purity acetonitrile yog cov organic hnyav nrog dav siv tau. Nws cov khoom siv tshuaj txiav txim siab nws lub luag haujlwm tseem ceeb thoob plaws kev tshawb fawb thiab kev tsim khoom lag luam.
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.
