Tetraethylammonium bromide CAS71-91-0

Kev Siv

1. Cov tshuaj catalyst hloov theem - Tetraethylammonium bromide yog ib qho tshuaj catalyst hloov theem uas siv ntau hauv cov tshuaj synthesis organic. Piv txwv li, hauv cov tshuaj tiv thaiv ntawm halogenated hydrocarbons thiab nucleophilic reagents, nws tuaj yeem txhawb nqa cov tshuaj tiv thaiv. Hauv cov tshuaj tiv thaiv alkylation, thaum halogenated alkanes tiv thaiv nrog cov tshuaj uas muaj hydrogen nquag (xws li phenols, cawv, carboxylic acids, thiab lwm yam), tetraethylammonium bromide tuaj yeem ua rau cov tshuaj tiv thaiv tshwm sim hauv qab cov xwm txheej me me. Vim tias nws tuaj yeem pab cov tshuaj reagents nucleophilic hloov los ntawm theem aqueous mus rau theem organic, ua rau cov tshuaj tiv thaiv mus zoo hauv theem organic. Piv txwv li, hauv cov tshuaj tiv thaiv alkylation ntawm phenylacetonitrile nrog halogenated alkanes, tetraethylammonium bromide tuaj yeem ua rau cov tshuaj tiv thaiv ntau ntxiv.

2. Cov tshuaj reagent ion pair chromatography - Tetraethylammonium bromide ua lub luag haujlwm tseem ceeb ua cov tshuaj reagent ion pair hauv ion pair chromatography. Nws tuaj yeem tsim cov ion pairs nrog cov analytes nrog cov nqi sib txawv, yog li hloov pauv tus cwj pwm khaws cia ntawm cov analytes. Thaum tshuaj xyuas cov tshuaj xws li cov organic bases lossis cov organic acids, los ntawm kev kho qhov concentration ntawm tetraethylammonium bromide, cov xwm txheej sib cais chromatographic tuaj yeem ua kom zoo dua. Piv txwv li, thaum tshuaj xyuas qee cov alkaloids, nws tuaj yeem tsim cov ion pairs nrog alkaloid cations, yog li cov alkaloids muaj lub sijhawm khaws cia kom zoo rau ntawm cov kab chromatographic rov qab, yog li ua tiav cov txiaj ntsig sib cais zoo dua.

3. Surfactant - Nws kuj tseem siv tau ua cationic surfactant. Hauv qee qhov kev sib xyaw ua ke ntawm emulsion polymerization, tetraethylammonium bromide tuaj yeem txo qhov nro ntawm qhov chaw thiab ua rau cov monomers tawg tau zoo dua hauv qhov system sib xyaw ua ke. Piv txwv li, hauv emulsion polymerization ntawm styrene, ntxiv cov tetraethylammonium bromide kom tsim nyog tuaj yeem ua rau cov dej styrene tawg tau zoo dua, uas yog qhov zoo rau kev nce qib ntawm cov tshuaj sib xyaw ua ke thiab tuaj yeem txhim kho kev ruaj khov ntawm cov polymer emulsion.

4. Lwm yam kev siv - Hauv kev tshawb fawb txog electrochemistry, tetraethylammonium bromide siv tau ua ib feem ntawm electrolytes. Hauv qee lub roj teeb lossis cov sensors electrochemical, nws tuaj yeem muab cov channel conduction ion. Piv txwv li, hauv qee cov khoom siv electrochemical raws li cov ion pauv membranes, tetraethylammonium bromide tuaj yeem pab tswj cov ion sib npaug ntawm ob sab ntawm daim nyias nyias, yog li ua kom ntseeg tau tias lub cuab yeej ua haujlwm ib txwm.
