Ukusetyenziswa
1. I-Phase transfer catalyst - I-Tetraethylammonium bromide sisixhobo esisetyenziswa kakhulu kwi-phase transfer catalyst kwi-organic synthesis reactions. Umzekelo, kwi-reaction phakathi kwe-halogenated hydrocarbons kunye ne-nucleophilic reagents, inokukhuthaza i-reaction. Kwi-alkylation reactions, xa i-halogenated alkanes isabela kunye nee-compounds ezine-hydrogen esebenzayo (ezifana ne-phenols, i-alcohols, i-carboxylic acids, njl.njl.), i-tetraethylammonium bromide inokwenza i-reaction yenzeke phantsi kweemeko ezithambileyo. Kuba inokunceda i-nucleophilic reagents ukuba idlule ukusuka kwi-aqueous phase ukuya kwi-organic phase, yenze i-reaction iqhubeke kakuhle kwi-organic phase. Umzekelo, kwi-alkylation reaction ye-phenylacetonitrile ene-halogenated alkanes, i-tetraethylammonium bromide inokunyusa ngempumelelo i-reaction venue.
2. I-reagent ye-chromatography ye-ion pair - I-Tetraethylammonium bromide idlala indima ebalulekileyo njenge-reagent ye-ion pair kwi-chromatography ye-ion pair. Ingenza ii-ion pairs ezine-analytes ezinee-reverse charges, ngaloo ndlela itshintsha indlela yokugcina ii-analytes. Xa kuhlalutywa ii-compounds ezifana ne-organic bases okanye ii-organic acids, ngokulungelelanisa uxinaniso lwe-tetraethylammonium bromide, iimeko zokwahlulwa kwe-chromatographic zinokwenziwa ngcono. Umzekelo, xa kuhlalutywa ii-alkaloids ezithile, ingenza ii-ion pairs ezine-alkaloid cations, ukuze ii-alkaloids zibe nexesha elifanelekileyo lokugcina kwikholamu ye-chromatographic yesigaba esibuyiselweyo, ngaloo ndlela zifezekisa iziphumo ezingcono zokwahlulwa.
3. I-Surfactant - Ingasetyenziswa njenge-cationic surfactant. Kwezinye ii-emulsion polymerization reactions, i-tetraethylammonium bromide inokunciphisa uxinzelelo lomphezulu kwaye ivumele ii-monomers ukuba zisasazeke ngcono kwinkqubo yokusabela. Umzekelo, kwi-emulsion polymerization ye-styrene, ukongeza isixa esifanelekileyo se-tetraethylammonium bromide kunokwenza amaconsi e-styrene asasazeke ngokulinganayo, nto leyo enceda ekuqhubekeni kwe-polymerization reaction kwaye inokuphucula uzinzo lwe-polymer emulsion.
4. Ezinye iindlela zokusebenza - Kwicandelo le-electrochemistry, i-tetraethylammonium bromide ingasetyenziswa njengenxalenye ye-electrolytes. Kwezinye iibhetri okanye ii-sensors ze-electrochemical, inokubonelela ngemijelo yokuqhuba i-ion. Umzekelo, kwezinye izixhobo ze-electrochemical ezisekelwe kwi-ion exchange membranes, i-tetraethylammonium bromide inokunceda ukugcina ibhalansi ye-ion kumacala omabini e-membrane, ngaloo ndlela iqinisekisa ukusebenza okuqhelekileyo kwesixhobo.
