| Tetrabutylammonium bromide Kev siv thiab kev sib xyaw |
| Physical thiab Chemical Properties | Tetrabutylammonium bromide, tseem hu ua tetrabutylammonium bromide. Dawb crystal, deliquescence. 118 degree melting point. Soluble hauv dej, cawv, ether thiab acetone, me ntsis soluble hauv benzene. Daim duab 1: tus qauv qauv ntawm tetrabutylammonium bromide |
| Daim ntawv thov | (1) Siv los ua reagent rau kev tsom xam cov organic synthesis. (2) Tetrabutylammonium bromide kuj yog 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, , 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 cov synthesis ntawm bacampicillin, sultamicillin zoo li. (5) Ion khub chromatography reagents, theem hloov catalyst. Bacampicillin, sultamicillin zoo li synthesis. |
| Siv | Tetrabutylammonium bromide (TBAB) yog quaternary ammonium compound. Nws yog feem ntau siv theem hloov pauv catalyst. Nws cov khoom interfacial tau kawm nyob rau hauv rooj plaub ntawm hydroxide pib tshwm sim. Qhov no tuaj yeem siv rau hauv kev nkag siab txog cov txheej txheem ntawm theem hloov pauv cov tshuaj tiv thaiv. TBAB tau tshaj tawm kom txo lub sijhawm khaws cia thiab tshem tawm qhov siab tshaj plaws los ntawm kev ua ib qho ion khub reagent thaum lub sijhawm chromatographic tsom xam ntawm quaternary ammonium compounds. Hauv lub xeev molten TBAB coj zoo li cov kua ionic uas yog ib qho kev cog lus ntsuab rau cov kuab tshuaj hauv cov organic synthesis. Nws cov molar kub muaj peev xwm, entropy thiab dawb zog muaj nuj nqi tau raug txiav txim. Tsis ntev los no, molten tetrabutylammonium bromide (TBAB) tau siv los ua cov tshuaj lom neeg tsawg thiab raug nqi IL hauv ntau qhov kev hloov kho hluavtaws. Tetrabutylammonium bromide (TBAB) tuaj yeem siv rau hauv lub xeev molten hauv cov txheej txheem hauv qab no: Synthesis ntawm (2S)-5-(3-phenyl-2-phthalimidylpropanoylamino) isophthalic acid. Synthesis ntawm alkyl-substituted pyrroles nyob rau hauv tsis muaj catalyst thiab organic hnyav. Synthesis ntawm dithioacetals los ntawm acetals los ntawm transthioacetalisation nyob rau hauv ib tug hnyav dawb ib puag ncig. Synthesis ntawm polyamides (PAs) los ntawm polymerization ntawm terephthalic acid thiab diisocyanates. Catalyze qhov sib ntxiv ntawm thiols rau conjugated alkenes. Dehydrochlorination ntawm poly (vinyl chloride). |
| kev npaj | Txoj Kev Npaj: Muaj ntau txoj hauv kev kom rov qab tau cov quaternary ammonium ion zoo.Prepared los ntawm cov tshuaj tiv thaiv ntawm tri-n-butylamine thiab n-butyl bromide. |
| Toxicity | Qhov ncauj qhov ncauj LD50 (nas): 590mg / kg. Inhalation, ingestion thiab daim tawv nqaij sib cuag tshuaj lom rau ntawm daim tawv nqaij, qhov muag thiab ua pa system irritation. Xav paub ntau ntxiv los ntawm ChemicalBook Xiaonan editor (2015-09-16). |
| Chemical Properties | dawb crystals los yog hmoov |
| Siv | Tetrabutylammonium Bromide yog siv nyob rau hauv synthesis ntawm polymer solar cells. Kuj tseem siv rau hauv kev sib txuas ntawm ib qho khoom siv ntsuab-lub teeb emitting electrochemical hlwb. |
| Txhais | ChEBI: Tetrabutylammonium bromide yog tetrabutylammonium ntsev nrog bromide ua tus anionic counterpart. Nws yog ib qho organic bromide ntsev thiab tetrabutylammonium ntsev. |
| cov txiaj ntsig | Tetrabutylammonium bromide yog ib puag ncig benign, tsis-volatile, tsis-flammable, tsis-corrosive, tsis tshua muaj nqi, lag luam muaj ammonium ntsev nrog siab thermal thiab tshuaj stability. Hauv TBAB, tetrabutylammonium ntsev tuaj yeem yaj hauv ob qho tib si aqueous thiab hauv cov kuab tshuaj organic, uas pab thauj cov dej-soluble anionic reactants mus rau theem organic. Ntxiv mus, molten TBAB kuj tau ua hauj lwm raws li ib tug npaum ionic kua los ua cov organic transformations nyob rau hauv hnyav-dawb tej yam kev mob[1]. |
