Tšebeliso

1. Sesebediswa sa phetiso ya mokgahlelo - Tetraethylammonium bromide ke sesebediswa sa phetiso ya mokgahlelo se sebediswang haholo dikarabelong tsa tlhahiso ya manyolo. Mohlala, karabelong pakeng tsa dihydrocarbon tse nang le halogenated le di-reagent tsa nucleophilic, e ka kgothaletsa karabelo. Dikarabelong tsa alkylation, ha di-alkanes tse nang le halogenated di arabela ka metsoako e nang le haeterojene e sebetsang (jwalo ka di-phenol, di-alcohol, di-carboxylic acid, jj.), tetraethylammonium bromide e ka etsa hore karabelo e etsahale tlasa maemo a bobebe. Hobane e ka thusa di-reagent tsa nucleophilic ho fetisetsa ho tloha mohatong wa metsi ho ya mohatong wa manyolo, e leng se etsang hore karabelo e tswele pele hantle mohatong wa manyolo. Mohlala, karabelong ya alkylation ya phenylacetonitrile e nang le di-alkanes tse nang le halogenated, tetraethylammonium bromide e ka eketsa chai ya karabelo ka katleho.

2. Reagent ea chromatography ea Ion pair - Tetraethylammonium bromide e bapala karolo ea bohlokoa e le reagent ea ion pair ho chromatography ea ion pair. E ka theha lipara tsa ion ka li-analyte tse nang le litefiso tse fapaneng, ka hona e fetola boitšoaro ba ho boloka ba li-analyte. Ha ho hlahlojoa metsoako e kang metheo ea organic kapa li-acid tsa organic, ka ho fetola mahloriso a tetraethylammonium bromide, maemo a karohano ea chromatographic a ka ntlafatsoa. ​​Mohlala, ha ho hlahlojoa li-alkaloid tse itseng, e ka theha lipara tsa ion ka li-cation tsa alkaloid, e le hore li-alkaloid li be le nako e loketseng ea ho boloka kholomong ea chromatographic ea mohato o khutlisitsoeng morao, ka hona li fihlella litlamorao tse betere tsa karohano.

3. Surfactant - E ka boela ea sebelisoa e le cationic surfactant. Likarabelong tse ling tsa emulsion polymerization, tetraethylammonium bromide e ka fokotsa tsitsipano ea bokaholimo 'me ea nolofalletsa li-monomers ho hasana hamolemo tsamaisong ea karabelo. Mohlala, ho emulsion polymerization ea styrene, ho eketsa tekanyo e loketseng ea tetraethylammonium bromide ho ka etsa hore marotholi a styrene a hasane ka ho lekana, e leng se thusang tsoelo-pele ea karabelo ea polymerization 'me se ka ntlafatsa botsitso ba emulsion ea polymer.

4. Ditshebediso tse ding - Lefapheng la electrochemistry, tetraethylammonium bromide e ka sebediswa e le karolo ya di-electrolyte. Dibetring tse ding kapa di-sensor tsa electrochemical, e ka fana ka dikanale tsa ho tsamaisa di-ion. Mohlala, disebedisweng tse ding tsa electrochemical tse thehilweng hodima di-membrane tsa phapanyetsano ya di-ion, tetraethylammonium bromide e ka thusa ho boloka botsitso ba di-ion mahlakoreng ka bobedi a lera, ka hona e netefatsa tshebetso e tlwaelehileng ya sesebediswa.

Ho paka le ho Romela

25KG/Moropa kapa ho ya ka ditlhoko tsa bareki.

Thomello: Mefuta e 6 ea thepa e kotsi 'me e ka tlisoa ka leoatle.

Boloka le ho boloka

Nako ea ho boloka: Likhoeli tse 24 ho tloha letsatsing la tlhahiso ka har'a sephutheloana sa pele se sa buloang se bolokiloe sebakeng se pholileng se omileng se se nang khanya ea letsatsi, metsi.
Ntlo ea polokelo e nang le moea o kenang, Ho omisa mocheso o tlase, E arotsoe ho li-oxidant, li-acid.
