Kev siv
1. Theem Hloov Catalyst - Tetraethylammonium Bromide yog cov feem ntau siv theem hloov catalystists. Piv txwv li, hauv cov tshuaj tiv thaiv ntawm halogenated hydrocarbons thiab nucleophilic reagents, nws tuaj yeem txhawb nqa cov tshuaj tiv thaiv. Nyob rau hauv alkylation cov tshuaj tiv thaiv, thaum halogenated alkanes hnov nrog cov laj kab uas muaj cov khoom siv ntau (xws li kab mob carboxylic, thiab lwm yam) yuav ua rau cov tshuaj tiv thaiv me me. Vim tias nws tuaj yeem pab nucleophilic reagents hloov chaw ntawm cov aqueous theem rau cov organic theem, ua rau cov tshuaj tiv thaiv ua rau cov organic. Piv txwv li, nyob rau hauv lub alkylation cov tshuaj tiv thaiv ntawm phenylacetonitrile nrog halogenated alkanes, Tetraethylammonium Bromide yuav ua tau zoo nce cov tshuaj tiv thaiv tawm los.
2. Ion khub chromatography reagent - Tetraethylammonium Bromide ua lub luag haujlwm tseem ceeb ua Ion khub chromatography. Nws tuaj yeem tsim ion khub nrog cov kws tshuaj ntsuam nrog cov nqi rov qab, yog li hloov pauv kev ua haujlwm ntawm cov kws tshuaj ntsuam. Thaum kev tshuaj xyuas cov chaw sib txuas xws li cov txheej txheem organic lossis cov organic acids, los ntawm kev kho cov kev sib cais ntawm cov kev sib cais, kev sib cais chromatographic muaj peev xwm ua tau zoo. Piv txwv li, thaum kev tshuaj xyuas qee cov alkaloids, nws tuaj yeem tsim ion khub nrog cov alkaloid cations, yog li ntawd alkaloid cont, yog li ua tiav kev sib cais zoo dua.
3. Surfactant - nws kuj tseem siv tau ua lub cationic surfactant. Hauv qee cov tshuaj tiv thaiv polulsy, Tetraethylammonium Bromide tuaj yeem txo qis cov npoo av thiab ua kom cov monomers kom tau txais kev cuam tshuam zoo dua hauv cov tshuaj tiv thaiv. Piv txwv li, hauv emulsion polymerization ntawm styrene, ntxiv ib qho kev tsim nyog los cuam tshuam rau kev nce qib ntawm cov neeg muaj peev xwm ua tau kev ruaj khov thiab tuaj yeem txhim kho qhov ruaj ntseg ntawm polsymer.
4. Lwm cov ntawv thov - hauv kev sib txuas ntawm Electrochemontry, Tetraethylammonium Bromide tuaj yeem siv los ua cov khoom sib xyaw ntawm electrolytes. Hauv qee cov roj teeb lossis hluav taws xob sensors, nws tuaj yeem muab cov ion conduction channel. Piv txwv li, hauv qee cov khoom siv electrochemical raws li ion txauv cov tshuaj ntsuab, zetraethylammonium bromide tuaj yeem pab saib xyuas cov kev sib npaug ntawm ob sab ntawm lub cuab yeej.
