Na TBAB e chefo?

Tetrabutylammonium bromide (TBAB),MF ke C16H36BrN, ke letsoai la quaternary ammonium. Hangata e sebelisoa e le mokhoa oa phetisetso ea mohato le ho organic synthesis. TBAB ke phofo e tšoeu ea kristale e nang le nomoro ea CAS 1643-19-2. Ka lebaka la thepa ea eona e ikhethang, ke reagent ea bohlokoa liketsong tse fapaneng tsa lik'hemik'hale. Potso e tloaelehileng mabapi le TBAB ke ho qhibiliha ha eona metsing. Ho feta moo, hangata ho na le matšoenyeho mabapi le hore na TBAB e chefo? Sehloohong sena, re tla hlahloba ho qhibiliha ha TBAB metsing 'me na TBAB e chefo?

Taba ea pele, ha re bue ka ho qhibiliha ha TBAB metsing.Tetrabutylammonium bromidee qhibiliha hanyane metsing. Ka lebaka la tlhaho ea eona ea hydrophobic, e na le ho qhibiliha ho tlase ho li-solvents tsa polar, ho kenyelletsa le metsi. Leha ho le joalo, TBAB e qhibiliha haholo linthong tse hlapollang tse kang acetone, ethanol le methanol. Thepa ena e etsa hore e be motsoako oa bohlokoa ho organic synthesis le lits'ebetso tse fapaneng tsa lik'hemik'hale tse hlokang li-catalysts tsa phetiso ea mekhahlelo.

TBABe sebelisoa haholo e le mokhoa oa ho fetisa mohato ho chemistry ea organic, e thusang ho fetisetsa li-reactants ho tloha karolong e 'ngoe ho ea ho e' ngoe. E khothalletsa maikutlo pakeng tsa li-reactants tse sa bonahaleng ka ho fetisetsa li-ion kapa limolek'hule ho tloha karolong e 'ngoe ho ea ho e' ngoe, kahoo e eketsa litekanyetso tsa karabelo le lihlahisoa. Ho feta moo, TBAB e ka boela ea sebelisoa ha ho etsoa lithethefatsi, lik'hemik'hale tsa temo le lik'hemik'hale tse ling tse ntle. Bokhoni ba eona ba ho eketsa katleho ea karabelo le khetho e etsa hore e be sesebelisoa sa bohlokoa bakeng sa tlhahiso ea mefuta e mengata ea metsoako.

Jwale, ha re bueng keTBABchefo? Tetrabutylammonium bromide e nkoa e le chefo haeba e ka nooa, e hema, kapa e kopana le letlalo. Ke habohlokoa ho sebetsana le motsoako ona ka hloko le ho latela mehato e nepahetseng ea tšireletso ha u e sebelisa. Ho hema TBAB ho ka baka ho teneha ha pampiri ea ho hema, 'me ho kopana ha letlalo ho ka baka ho teneha le dermatitis. Ho kenngoa ha TBAB ho ka baka ho teneha ka mpeng le litlamorao tse ling tse mpe. Ka hona, ts'ebeliso ea lisebelisoa tse nepahetseng tsa ts'ireletso (mohlala, liatlana le lijase tsa lab) li bohlokoa ha u sebetsana le TBAB.

Ho feta moo,TBABe lokela ho lahloa ho latela melao le litataiso tsa litšila tse kotsi tsa lehae. Mekhoa e nepahetseng ea ho boloka le ho lahla e lokela ho lateloa ho thibela tšilafalo ea tikoloho le kotsi e ka bang teng bophelong ba batho.

Ka kakaretso,tetrabutylammonium bromide (TBAB)E qhibiliha hanyenyane ka metsing empa e bonolo ho qhibiliha ka har'a metsoako ea lintho tse phelang, e leng se etsang hore e be motsoako oa bohlokoa ho organic synthesis le phase transfer catalysis. Tšebeliso ea eona ho k'hemistri ea tlhaho, motsoako oa lithethefatsi le mekhoa e meng ea lik'hemik'hale e totobatsa bohlokoa ba eona lefapheng la lipatlisiso le tlhahiso ea lik'hemik'hale. Leha ho le joalo, ho bohlokoa ho lemoha chefo e ka bang teng ea TBAB le ho nka mehato e hlokahalang ha u tšoara le ho lahla motsoako ona. Ho latela melaoana ea ts'ireletso le litataiso ho bohlokoa ho netefatsa ts'ebeliso e bolokehileng ea TBAB le ho fokotsa likotsi tse amanang le tsona.
