Siv:Tetraethylammonium Bromide, tuaj yeem siv los ua ib qho chaw ntawm Tetraethylammonium ions rau ntau yam kev tshawb fawb. Nws kuj tseem muaj peev xwm thaiv K + raws hauv ntau cov ntaub so ntswg. Tetraethylammonium bromide (TeaB) catchalyzes cov synthesis ntawm cov leeg nqaij lossis disuloxide los ntawm oxidation ntawm cov sulfoxides thiab thawj lub carbon monombide rau ib-carbon dehomologated NITRILES.TEA yuav tseem siv tau los ua tus qauv organic rau synthesize beta.
Cov ncauj lus kom ntxaws thiab cov ntawv thov
Tetraethylammonium Bromide (TeaBr) yog cov ntsev ntawm ammonium nrog cov mis nyuj (C2h5) 4Nr. Nws yog lub teb chaws dawb crystalline uas yog soluble hauv polar solvents xws li dej thiab cawv.
Teebr yog ib txwm siv nyob rau hauv cov organic synthesis ua ib theem hloov catalyst. Nws pab hloov ntawm reactants thiab ions ntawm cov theem imiscible los ntawm kev tsim cov pob zeb nrog actions thiab txhim kho lawv cov solubility hauv organic cov kuab tshuaj. Qhov no ua rau cov kev coj ua kom ua tau yooj yim dua thiab xaiv tau. Teebr tau muaj txiaj ntsig tshwj xeeb hauv kev hloov pauv xws li nucleophilic hloov chaw, Aldol cov hws, thiab polymerizations.
Ntxiv rau nws lub luag haujlwm ua catalyst, TEAMBR tseem pom cov ntawv thov hauv lwm qhov chaw. Qee qhov siv tau muaj xws li:
Cov kuab tshuaj extraction:Teebr tuaj yeem siv los rho tawm thiab cais cov hlau ions ntawm cov kev daws teeb meem aqueous. Nws pab nyob rau hauv extraction ntawm cov hlau xws li platinum, palladium, thiab kub.
Kho qauv:Teebr tau raug siv los hloov cov khoom saum npoo av ntawm cov ntaub ntawv thiab txhim kho lawv cov adhesion lossis dispersibility. Nws tau ua haujlwm hauv kev tsim cov txheej txheem, xim av, thiab cov nplaum.
Kev Tshawb Xyuas Kev Tshawb Xyuas thiab Kev Tshawb Fawb Biochemical:Teeb yog siv nyob rau hauv ntau biological thiab biochemical kev tshawb fawb raws li lub stabilizer lossis additive. Nws pab hauv cov enzymes, cov protein, thiab lwm cov biomolecules, thiab tuaj yeem pab ion pauv kev hloov pauv thiab cov txheej txheem protein reniiluration.
Kev tsom xam thiab sib cais cov txuj ci:Teebr yog ib qho kev siv tshuaj ntsuam ib txwm muaj nyob hauv ion cov chromatography thiab capillary electrophoresis. Nws pab hauv kev sib cais thiab kev txheeb xyuas ntawm cov tshuaj tiv thaiv sib txawv raws li lawv cov ionic cov khoom.
Cov Khoom Siv Tshuaj:Teebr tau tshawb nrhiav raws li lub peev txheej hauv kev siv tshuaj yeeb tshuaj vim nws biocompatibility thiab muaj peev xwm los pab siv tshuaj yeeb.
Zuag qhia tag nrho, Tetraethylammonium Bromide yog ib qho kev siv hluav taws xob ntau yam hauv cov khoom siv hluav taws xob, kev hloov kho hlau, thiab ntau txoj kev tshawb fawb. Nws cov khoom tshwj xeeb ua nws cov cuab yeej tseem ceeb rau ntau yam kev tshawb fawb thiab kev muaj kev muaj cov txheej txheem.
