Sebenzisa:I-Tetraethylammonium Bromide, ingasetshenziswa njengomthombo wama-tetraethylammonium ion ezifundo ezahlukahlukene zemithi. Inamandla okuvimba iziteshi ze-K + ezicubu ezahlukahlukene. I-Tetraethylammonium Bromide (Teab) i-synthesis yama-thioesters ngokuhlanganiswa kwama-alldehyde noma ama-lu-ioodoxybenzoic acid (i-ludoxybenzoic acid (IBX), e-Oxidation of Sulfoxides to Sulfoxides kanye nama-carboxides aphambili e-carbon Ama-Nitriles.Teab angasetshenziswa futhi njengethempulethi ye-organic ukuhlanganisa i-zeolite beta.
Isingeniso kanye Nezicelo ezinemininingwane
I-Tetraethylammonium Bromide (Teabr) Usawoti we-amonmonium we-quaternary ngefomula yamakhemikhali (C2HH5) 4NBR. Yikhompiyutha emhlophe ye-crystalline encibilikayo emaphethelweni we-solvents anjengamanzi notshwala.
I-teaB isetshenziswa kakhulu ekuhlolweni kwe-organic njenge-tatalyst yesigaba. Inika amandla ukuhanjiswa kwama-reactants nama-ion phakathi kwezigaba ezingenangqondo ngokwakha izakhiwo nge-anions kanye nokwenza ngcono i-solubity yazo ku-solvents ye-organic. Lokhu kwenza ukusabela kuqhubeke kahle nangokukhetha. I-TeaB ilusizo ikakhulukazi ekuphenduleni njengokufaka esikhundleni se-nucleophilic, ama-aldol amalangabi, nama-polymerizations.
Ngaphezu kwendima yayo njenge-catalyst, itiye futhi lithola izinhlelo zokusebenza kwezinye izindawo. Okunye ukusetshenziswa okuphawulekayo kufaka:
Ukukhishwa Kwe-Solvent:I-TeaBB ingasetshenziselwa ukukhipha futhi ihlukanise i-ion yensimbi kusuka ezixazululweni zamanzi. Kuyasiza ekukhishweni kwezinsimbi ezinjengePlatinamu, iPalladium neGolide.
Ukuguqulwa komhlaba:I-TeaBB isetshenziselwe ukuguqula izakhiwo ezingaphezulu kwezinto zokwakha futhi zithuthukise ukunamathela kwazo noma ukuhlakazwa. Kuqashwa ekwenziweni kwezimbozo, upende, kanye nezinamathela.
Ucwaningo lwebhayoloji kanye ne-biochemical:I-TeaBB isetshenziswa ezifundweni ezahlukahlukene zebhayoloji kanye ne-biochemical njenge-stabilizer noma isengezo. Kuyasiza ekulondolozeni ama-enzyme, amaprotheni, nakwamanye ama-biomolecule, futhi angasiza nasekuhlolweni kwe-Ion Exchange kanye nezinqubo zokuvuselela kabusha kwamaprotheni.
Ukuhlaziywa kanye namasu wokuhlukanisa:I-TEABR iyindilinga ejwayelekile e-Ion Chromatography ne-Capillary Electrophoresis. Isiza ekwehlukanisweni nasekukhonjweni kokuhlaziywa okuhlukile ngokuya ngezakhiwo zazo ze-ionic.
Izinhlelo Zokulethwa Kwezidakamizwa:I-TeaB ibhekele njengengxenye engaba khona kwezinhlelo zokulethwa kwezidakamizwa ngenxa yokuthambekela kwayo kanye nekhono lokwenza lula ukukhishwa kwezidakamizwa.
Sekukonke, iTetraethylammonium Bromide iyindawo ehlukahlukene enezicelo ezahlukahlukene ekuhlolweni kwe-organic, ukukhishwa kwensimbi, ukuguqulwa komhlaba, kanye nezinkundla ezahlukahlukene zokucwaninga. Izakhiwo zayo ezihlukile zikwenza ithuluzi elibalulekile ezinhlobonhlobo zezinqubo zesayensi nezimboni.
