Zoo siv
Canonical luag nyav:C [N +] (c) (c) C. [CL-]
Siv:1. Nws tuaj yeem siv ua Polarographic Of ofGents uas tau siv dav hauv kev lag luam hluav taws xob.
2. Tetramethylammonium chloride is the phase transfer catalyst in organic synthesis with its catalytic activity being stronger than triphenylphosphine and triethylamine. Nyob rau hauv chav tsev kub, nws yog volathatalline hmoov, thiab yog volatile, irritant, thiab yooj yim rau nqus dej noo. Nws yog yooj yim soluble hauv methanol yooj yim, soluble hauv dej thiab kub ethane ethanol tab sis insoluble hauv ethero thiab chloroform. Raug rhuab rau saum 230 ° C ua rau nws decomposition rau hauv trimethylamine thiab methyl chloride. Nruab nrab nruab nrab ntawm koob tshuaj (nas, intraperntoneal) yog ib ncig 25mg / kg. Nws kuj tseem siv rau cov synthesis ntawm ua kua lead ua kua crystal epoxy compound, thiab Pope thiab Polarographic tsom xam, nrog rau kev lag luam hluav taws xob. Tshuaj Nruab Nrab Nruab Nrab, catalyst, inhibitor. Cov tshuaj pleev ib ce n-hydroxyphthhaltalide thiab xanthone yuav siv tau los ua cov aerobic oxidation ntawm hydrocarbons ntawm cov pa roj oxygenated. Nws kuj tseem siv tau los ua theem hloov catalyst rau cov synales ntawm aryl chlorides ntawm cov poov tshuaj fluoride ua kua roj-kua. TMAC yuav siv tau cov txheej txheem hauv ion kom pom qhov nce ntawm PH kom nkag siab cov cwj pwm ntawm catalyst [MCM-41 siv KnooVenagel qauv condensation.
Cov lus qhia ntxaws ntxaws
Tetramethylammonium chloride, tseem hu ua TMAC lossis TMA chloride, yog cov ntsev ammonium. Nws yog tsim ntawm nruab nrab nitrogen atom borted mus rau plaub methyl pawg thiab ib tug chloride ion. Cov compound no muaj cov mis roj av ntawm (ch3) 4ncl.
TMAC yog tus dawb crystalline khoom nrog tus yam ntxwv tsw ntxhiab. Nws yog soluble heev hauv dej thiab muaj qhov tsis tshua muaj siab, ua kom yooj yim nkag tau thiab siv rau ntau yam kev siv.
Daim ntawv thov
Tetramethilmonium chloride (TMAC) muaj ob peb daim ntawv thov hauv ntau kev lag luam. Qee cov ntawv thov muaj xws li:
Catalyst thiab reagent:TMAC feem ntau siv los ua theem hloov catalyst hauv cov synthic synthesis. Nws ua rau cov tshuaj tiv thaiv ntawm cov kuab tshuaj immiscible los ntawm kev hloov pauv ntawm reactants thiab ions thoob phases. Nws yog tshwj xeeb siv nyob rau hauv kev hloov pauv xws li nucleophilic hloov thiab Qoob loo ammonium ntsev.
Surfactant:TMAC ua raws li surfactant, txo cov npoo nro thiab txhim kho cov ntub thiab dispersing cov khoom ntawm cov kua. Nws pom cov ntawv thov hauv cov qauv ntawm cov tshuaj ntxuav, cov nplaum, cov xim nplaum, thiab emulsions.
Kev Siv Hluav Taws Xob:TMAC yog siv ua electrolyte addectitive hauv roj teeb thiab roj hlwb los txhim kho lawv cov kev ua tau zoo thiab kev ruaj khov. Nws pab tswj cov ionic sib npaug thiab kev coj ua hauv lub hlwb.
Ion chrataphy:TMAC yog siv los ua tus qauv siv hauv ion chratography los pab tshawb xyuas thiab cais cov tshuaj sib txawv raws li lawv cov ionic cov khoom. Nws pab hauv kev txiav txim siab cov kev ua kom haum ntawm ntau ions hauv cov kua ua kua.
Capillary Electrophoresis:TMAC tuaj yeem ua cov electrolyte hauv capillary electroprophoresis, uas nws pab sib cais thiab ntsuas cov kev sib cais raws li lawv txoj kev sib raug zoo thiab them nyiaj.
Kev Tshawb Fawb Ib puag ncig:TMAC tau ua haujlwm hauv kev tshawb fawb ib puag ncig los tshawb xyuas cov ion kev cuam tshuam, thauj, thiab faib tawm hauv ntau yam. Nws yog qhov tseem ceeb tshaj plaws hauv kev coj cwj pwm ntawm cov organic organic thiab kawm lawv txoj hmoo hauv cov chaw sib txawv.
Cov no tsuas yog qee qhov piv txwv ntawm cov ntawv thov ntawm tetramethylammonium chloride. Nws cov khoom muaj ntau yam ua rau nws muaj nuj nqis hauv ntau thaj teb, electrochemistry, electrochemistry, kev tshawb fawb analyerical, thiab kev tshawb fawb anentalis, thiab ib puag ncig kev tshawb fawb.
