Tetrabutylammonium bromide feem ntau yog siv raws li hauv qab no:
I. Raws li theem hloov catalyst:
Txhawb nqa cov tshuaj tiv thaiv organic: Nws tuaj yeem hloov cov reactants nyob rau hauv aqueous theem (los yog organic theem) mus rau lub organic theem (los yog aqueous theem), ua kom cov reactants uas nyuaj rau reactants nyob rau hauv ob theem mus smoothly, yog li ntawd zoo heev txhim kho cov tshuaj tiv thaiv tus nqi thiab efficiency. Piv txwv li, nyob rau hauv alkylation cov tshuaj tiv thaiv, piv nrog cov pa txoj kev, kev siv ntawm tetrabutylammonium bromide zam lub mob hnyav ntawm anhydrous ua hauj lwm thiab txhim kho cov khoom yields.
Kev siv dav hauv ntau hom tshuaj tiv thaiv: Nws tuaj yeem siv los npaj carbene- hom tshuaj sib xyaw (R₂C- hom tshuaj sib xyaw) thiab tom qab ntawd tsim cov nitriles, isonitriles, haloalkanes, dichlorocyclopropane derivatives, hydroxycarboxylic acids, diazolysismethane, thiab lwm yam. cyanide-Halogen ion hloov cov tshuaj tiv thaiv, cov tshuaj tiv thaiv condensation, cov tshuaj tiv thaiv ntxiv, cov tshuaj tiv thaiv polymerization, cov tshuaj tiv thaiv carbene cycloaddition, thiab tshem tawm cov tshuaj tiv thaiv, thiab lwm yam.
II. Raws li ion-pairing reagent: Thaum siv cov kua chromatography los soj ntsuam cov qauv uas muaj peev xwm ionization muaj zog, ntxiv tetrabutylammonium bromide tuaj yeem ua ke cov ions ntawm cov tshuaj ntsuam xyuas los ua cov molecules khaws cia rau hauv kem, yog li txhim kho cov nyhuv sib cais. Raws li nws cov concentration nce, tus nqi khaws cia ntawm anions nce, thiab kev sib cais los ntawm kev sib koom ua ke ions kuj txhim kho. Nyob rau hauv ib tug tej yam concentration ntau, anions thiab lwm yam coexisting ions tuaj yeem raug cais tawm.
III. Raws li ib tug reagent rau polarographic tsom xam: Nws muaj cov ntawv thov tseem ceeb hauv kev txheeb xyuas polarographic thiab tuaj yeem pab hauv kev tshuaj xyuas thiab tshawb xyuas cov tshuaj.
IV. Kev siv tshuaj synthesis:
Raws li ib tug catalyst los yog theem hloov neeg sawv cev: Nws yuav siv tau nyob rau hauv lub synthesis ntawm tshuaj intermediates xws li benzyltriethylammonium chloride, ethyl cinnamate, thiab pseudoionone. Nws tuaj yeem siv rau hauv kev sib txuas ntawm cov tshuaj organic xws li bacampicillin thiab sultamicillin. Hauv kev sib xyaw ua ke ntawm cov tshuaj tiv thaiv kab mob ntshav qab zib xws li dapagliflozin nrog cov txheej txheem tshiab ntawm kev ua, nws kuj tuaj yeem siv los ua cov catalyst.
Raws li kev hloov pauv bromine: Nws tuaj yeem siv los ua bromine hloov pauv los koom nrog hauv kev sib txuas ntawm sugammadex, tus neeg sawv cev rov qab rau cov leeg nqaij so, thiab tiopronin, tus neeg sawv cev rau kev txhim kho daim siab ua haujlwm thiab metabolic detoxification.
V. Kev npaj lwm yam tetrabutylammonium ntsev: Ntau lwm cov ntsev tetrabutylammonium tuaj yeem npaj los ntawm kev hloov ntsev.
VI. Kev siv hauv cov khoom siv science: Los ntawm kev sib xyaw nrog polyethylene glycol thiab lwm yam, sib sib zog nqus eutectic kuab tshuaj tuaj yeem npaj tau. Cov kuab tshuaj no muaj peev xwm siv tau rau hauv thaj chaw ntawm cov khoom siv hluavtaws thiab kev ua haujlwm.
