Tetrabutylammonium Bromide (TBAB) (CAS: 1643-19-2)
(1) TBAB yog siv los ua reagent rau kev tsom xam cov organic synthesis.
(2) Tetrabutylammonium Bromide yog cov khoom siv tshuaj lom neeg hauv khw.Nws yog ib qho ion-pair reagent thiab ib qho kev hloov mus rau theem catalyst.
Theem hloov catalyst, hu ua PTC, muaj peev xwm hloov lub aqueous theem (los yog organic theem) mus rau cov organic theem (los yog aqueous theem) catalyst, uas yuav ua rau cov tshuaj tiv thaiv ntawm lub aqueous theem thiab cov organic theem ntawm catalyst.PTC muaj lub luag haujlwm ntawm kev hloov pauv qib ntawm ion kev daws teeb meem, ua rau muaj kev ua haujlwm ntawm cov tshuaj tiv thaiv ion, ua kom ceev cov tshuaj tiv thaiv thiab lwm yam.Kev daws qhov teeb meem yav dhau los hauv ob theem ntawm cov tshuaj tiv thaiv yog qhov nyuaj rau kev hnov mob.
Feem ntau quaternary ammonium ntsev theem hloov catalysts yog: benzyl triethyl ammonium chloride, trioctyl methyl ammonium chloride, tetramethyl ammonium bromide, tetrapropylammonium chloride, tetrabutylammonium bromide, tetrabutyl ammonium benzium iodide, ide, octyl triethylammonium bromide.
Theem hloov catalyst yog dav siv nyob rau hauv cov organic synthesis: R2C rau kev npaj cov tebchaw (carbene hom compound), ntxiv kev npaj ntawm cov coj nitrile, isonitrile, Halon, dichloromethane cyclopropane derivatives, hydroxy acids thiab diazomethane.Rau cov tshuaj tiv thaiv alkylation, piv nrog cov txheej txheem ib txwm, kom tsis txhob muaj qhov hnyav ntawm kev ua haujlwm qhuav, thiab cov txiaj ntsig siab, nws kuj tuaj yeem siv rau hauv cov tshuaj tiv thaiv redox, ester hydrolysis, hloov cov tshuaj tiv thaiv, cov tshuaj tiv thaiv condensation, ntxiv cov tshuaj tiv thaiv, cov tshuaj tiv thaiv polymerization, ntxiv cov tshuaj tiv thaiv. carbon thiab tshem tawm cov tshuaj tiv thaiv thiab lwm yam.
(3) Rau cov organic synthesis intermediates, theem hloov catalyst
(4) Ion-pairing reagents rau synthesis ntawm bacampicillin, sultamicillin zoo li.
(5) Ion khub chromatography reagents, theem hloov catalyst.Bacampicillin, sultamicillin zoo li synthesis.
