Sodium trifluoromethanesulfonate CAS: 2926-30-9

Sodium trifluoromethanesulfonate, CF3SO3Na, ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam vim nws cov khoom siv tshuaj lom neeg tshwj xeeb thiab kev hloov pauv tau yooj yim. Cov Khoom Sodium trifluoromethanesulfonate feem ntau pom muaj nyob rau hauv daim ntawv ntawm cov khoom dawb crystalline. Nws yog soluble heev hauv cov kuab tshuaj polar xws li dej thiab acetone tab sis insoluble hauv cov kuab tshuaj uas tsis yog polar xws li hexane. Cov tshuaj no yog hygroscopic, nqus cov dej noo los ntawm huab cua. Nws muaj lub ntsiab lus melting siab thiab tseem ruaj khov nyob rau hauv ntau qhov kub thiab txias thiab siab, uas ua rau nws siv tau zoo ua tus catalyst hauv ntau yam tshuaj lom neeg. Siv Catalysis: Sodium trifluoromethanesulfonate yog siv dav ua tus catalyst acid muaj zog hauv organic synthesis. Nws pab txhawb cov tshuaj xws li esterifications, alkylations, thiab rearrangements los ntawm kev txo qis lub zog ua kom muaj zog thiab ua kom nrawm dua cov nqi tshuaj. Nws cov txiaj ntsig zoo los ntawm nws lub peev xwm los protonate substrates zoo nyob rau hauv cov xwm txheej tsis hnyav, ua rau nws tsim nyog rau kev tsim cov molecule nyuaj. Theem-Hloov Catalyst: Ntxiv rau nws lub luag haujlwm ua tus catalyst acid, sodium trifluoromethanesulfonate ua haujlwm ua tus catalyst hloov theem. Nws pab txhawb kev hloov pauv ntawm cov tshuaj reactants ntawm cov theem tsis sib xyaw (feem ntau ntawm cov theem aqueous thiab organic), yog li ua kom cov tshuaj tiv thaiv ua haujlwm zoo thiab cov txiaj ntsig hauv ntau yam kev hloov pauv tshuaj. Electroplating: Cov tshuaj no siv rau hauv cov txheej txheem electroplating, tshwj xeeb tshaj yog rau kev tso cov hlau hauv qab tswj hwm vim nws cov tshuaj lom neeg ruaj khov thiab muaj peev xwm hloov kho cov tshuaj tiv thaiv kinetics. Kev tsim kho Sodium trifluoromethanesulfonate tuaj yeem tsim los ntawm kev ua kom tsis muaj zog trifluoromethanesulfonic acid (CF3SO3H) nrog sodium hydroxide (NaOH). Cov tshuaj tiv thaiv ua rau sodium trifluoromethanesulfonate nrog rau dej ua cov khoom siv ntxiv. Cov tshuaj no tuaj yeem raug rho tawm los ntawm kev siv crystallization thiab purified kom ua tiav cov tshuaj purity siab rau cov ntawv thov kev lag luam. Hauv kev xaus, sodium trifluoromethanesulfonate yog cov tshuaj sib xyaw ua ke tseem ceeb hauv kev tsim cov organic, catalysis, thiab electroplating. Nws cov khoom sib txawv ua cov tshuaj catalyst muaj zog thiab cov neeg sawv cev hloov pauv theem ua rau nws siv dav hauv cov txheej txheem kev lag luam, pab txhawb rau kev nce qib ntawm cov thev naus laus zis tshuaj thiab kev txhim kho cov ntaub ntawv tshiab.
