2. Ionic kua
TBAB cas 1643-19-2yog dav siv nyob rau hauv zus tau tej cov ionic kua. Ionic kua yog ib chav kawm ntawm cov ntsev uas feem ntau muaj nyob hauv cov kua hauv chav tsev kub. Lawv muaj volatility tsawg, siab tshuaj stability, thiab zoo heev solvency zog. Ionic kua tau pom siv nyob rau hauv ntau qhov chaw, suav nrog cov kuab tshuaj rho tawm, kev tshawb fawb sib cais, thiab kev siv electrochemical.
Cov khoom tshwj xeeb ntawmTBAB Tetrabutylammonium bromideRaws li quaternary ammonium ntsev yog nws lub peev xwm los tsim cov kua ionic ruaj khov nrog anions xws li chloride, bromide, thiab azide. Kev hloov pauv hauv kev sib xyaw ion tau ua rau muaj ntau yam ntawm cov kua ionic, txhua tus muaj cov khoom tshwj xeeb thiab kev siv.
3. Tshuaj ntsuam xyuas
TBAB cas 1643-19-2yog nquag siv nyob rau hauv tshuaj tsom xam raws li ib theem hloov catalyst. Theem hloov catalysis yog cov tshuaj tiv thaiv ntawm ob theem insoluble uas cov catalyst tuaj yeem pab txhawb kev hloov ntawm ions lossis molecules ntawm theem. TBAB cas 1643-19-2 feem ntau yog ntxiv rau theem aqueous los pab txhawb cov tshuaj tiv thaiv, thiab cov kuab tshuaj organic yog ntxiv rau theem ob.
Txoj kev no tau siv dav hauv kev tshuaj xyuas ntawm ntau lub tebchaw xws li amino acids, organosulfur compounds, thiab amines. Tsis tas li ntawd, nws cov solubility siab ua rau nws yog ib qho khoom siv zoo tshaj plaws hauv kev rho tawm thiab ua kom huv ntawm cov tshuaj.
4. Polymer Synthesis
TBAB cas 1643-19-2tau siv nyob rau hauv synthesis ntawm ntau yam polymers. Nws dual solubility ua rau nws ua raws li theem hloov pauv catalyst uas txhawb kev sib cuam tshuam ntawm polymer thiab monomer. Nws yog feem ntau siv rau hauv kev sib txuas ntawm cov ntaub ntawv xws li polyethers, polycarbonates, thiab polyesters.
Tsis tas li ntawd, Tetrabutylammonium bromide TBAB kuj tseem tuaj yeem muab ntxiv rau cov tshuaj tiv thaiv sib xyaw kom hloov qhov loj thiab morphology ntawm cov khoom siv polymer. Qhov loj ntawm cov saw hlau polymeric tuaj yeem tswj tau thiab tswj tau los ntawm qhov sib txawv ntawm cov concentration ntawm TBAB.
Xaus
