Kagwiritsidwe Ntchito

1. Chothandizira kusamutsa gawo - Tetraethylammonium bromide ndi chothandizira kusamutsa gawo chomwe chimagwiritsidwa ntchito kwambiri mu zochita za organic synthesis. Mwachitsanzo, mu reaction pakati pa halogenated hydrocarbons ndi nucleophilic reagents, imatha kulimbikitsa reaction. Mu alkylation reactions, pamene halogenated alkanes imachita ndi mankhwala okhala ndi active hydrogen (monga phenols, alcohols, carboxylic acids, etc.), tetraethylammonium bromide ingapangitse reaction kuchitika pansi pa mikhalidwe yofatsa. Chifukwa ingathandize nucleophilic reagents kusamutsa kuchokera ku aqueous phase kupita ku organic phase, zomwe zimapangitsa reaction kupitilira bwino mu organic phase. Mwachitsanzo, mu alkylation reaction ya phenylacetonitrile yokhala ndi halogenated alkanes, tetraethylammonium bromide imatha kukulitsa bwino reaction produce.

2. Chogwirizira cha chromatography cha Ion pair - Tetraethylammonium bromide imagwira ntchito yofunika kwambiri ngati chogwirizira cha ion pair mu chromatography ya ion pair. Imatha kupanga ma ion pair ndi analytes okhala ndi ma charge otsutsana, motero imasintha momwe analytes amasungira. Pofufuza mankhwala monga organic bases kapena organic acids, posintha kuchuluka kwa tetraethylammonium bromide, mikhalidwe yolekanitsa chromatographic ikhoza kukonzedwa. Mwachitsanzo, pofufuza ma alkaloids ena, imatha kupanga ma ion pair ndi ma alkaloid cations, kuti ma alkaloids akhale ndi nthawi yoyenera yosungira pa reversed-phase chromatographic column, potero amapeza zotsatira zabwino zolekanitsa.

3. Surfactant - Ingagwiritsidwenso ntchito ngati cationic surfactant. Mu emulsion polymerization reactions zina, tetraethylammonium bromide imatha kuchepetsa kupsinjika kwa pamwamba ndikulola ma monomers kuti azifalikira bwino mu reaction system. Mwachitsanzo, mu emulsion polymerization ya styrene, kuwonjezera kuchuluka koyenera kwa tetraethylammonium bromide kungapangitse madontho a styrene kufalikira mofanana, zomwe zimathandiza kuti polymerization reaction ipite patsogolo ndipo zingathandize kuti polymerization emulsion ikhale yolimba.

4. Ntchito Zina - Mu gawo la electrochemistry, tetraethylammonium bromide ingagwiritsidwe ntchito ngati gawo la ma electrolyte. Mu mabatire ena kapena masensa a electrochemical, imatha kupereka njira zoyendetsera ma ion. Mwachitsanzo, mu zida zina zamagetsi zochokera ku ma ion exchange membranes, tetraethylammonium bromide ingathandize kusunga bwino ma ion mbali zonse ziwiri za nembanemba, potero kuonetsetsa kuti chipangizocho chikugwira ntchito bwino.

Kulongedza ndi Kutumiza

25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.

Kutumiza: Mitundu 6 ya katundu woopsa ndipo imatha kutumizidwa kudzera panyanja.

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
