I-Tetrabutylammonium bromide (TBAB)usawoti we-quaternary ammonium onefomula yamakhemikhali (C4H9)4NBr. Isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni, yamakhemikhali, neyemithi. Lesi sihloko sizoxoxa ngezicelo ezahlukahlukene ze-TBAB futhi sigqamise ukubaluleka kwayo kulezi zimboni.
1. I-Catalyst in Organic Synthesis
I-Tetrabutylammonium bromide TBABiyi-catalyst ethandwayo ekuphenduleni kwe-organic synthesis. Isetshenziswe ekuphenduleni okufana nokusabela kwe-Mitsunobu, ukusabela kwe-Wittig, nokusabela kwe-esterification. Uma ingezwe ngamanani amancane, i-TBAB ingasheshisa izinga lokusabela futhi ithuthukise isivuno.
Isici esiyingqayizivele se-Tetrabutylammonium bromide cas 1643-19-2 yikhono layo lokuncibilika kuzo zombili izincibilikisi ze-polar ne-nonpolar. Lesi sici sikwenza kube yi-catalyst ekahle yokusabela okubandakanya kokubili okuphakathi kwendawo epholile nengenayo i-polar. Ngenxa yalokho, i-TBAB iyingxenye ebalulekile ekuhlanganisweni kwezinhlanganisela ezihlukahlukene ezifana nemithi, ama-flavour, namakha.
2. Ionic Liquids
I-TBAB cas 1643-19-2isetshenziswa kabanzi ekukhiqizeni uketshezi lwe-ionic. Uketshezi lwe-ionic yikilasi likasawoti elivame ukuba khona njengoketshezi ekamelweni lokushisa. Zinokuguquguquka okuphansi, ukuqina kwamakhemikhali aphezulu, kanye nezakhiwo ezinhle kakhulu ze-solvency. Uketshezi lwe-ionic zithole ukusetshenziswa emikhakheni eyahlukene, okuhlanganisa ukukhishwa kwezincibilikizi, isayensi yokuhlukanisa, kanye nokusetshenziswa kwe-electrochemical.
Impahla eyingqayizivele yeI-TBAB Tetrabutylammonium bromidenjengosawoti we-ammonium we-quaternary yikhono lawo lokwenza uketshezi lwe-ionic oluzinzile ngama-anion afana ne-chloride, i-bromide, ne-azide. Ukuguquguquka kwezinhlanganisela ze-ion kuholele ekukhiqizweni koketshezi oluningi lwe-ionic, ngalunye olunezici ezihlukile nezindlela zokusebenza.
3. Ukuhlaziywa Kwamakhemikhali
I-TBAB cas 1643-19-2isetshenziswa kaningi ekuhlaziyweni kwamakhemikhali njenge-catalyst yokudlulisa isigaba. I-catalysis yokudlulisa isigaba iwukusabela phakathi kwezigaba ezimbili ezingancibiliki lapho i-catalyst ingenza kube lula ukudluliswa kwama-ion noma ama-molecule phakathi kwezigaba. I-TBAB cas 1643-19-2 ivamise ukungezwa esigabeni samanzi ukuze kube lula ukusabela, futhi i-organic solvent yengezwa njengesigaba sesibili.
Le ndlela isetshenziswe kakhulu ekuhlaziyweni kwezinhlanganisela ezihlukahlukene njengama-amino acid, i-organosulfur compounds, nama-amine. Ukwengeza, ukuncibilika kwayo okuphezulu kuyenza ibe yingxenye ekahle ekukhishweni nasekuhlanzweni kwamakhemikhali.
4. I-Polymer Synthesis
I-TBAB cas 1643-19-2isetshenziswe ekuhlanganiseni ama-polymer ahlukahlukene. Ukunyibilika kwayo okukabili kuyenza isebenze njengesisusa sokudlulisa isigaba esikhuthaza ukusebenzisana phakathi kwe-polymer ne-monomer. Ngokuvamile isetshenziswa ekuhlanganiseni izinto ezifana polyethers, polycarbonates, kanye polyester.
Ngaphezu kwalokho, i-Tetrabutylammonium bromide TBAB nayo ingangezwa ekuxubeni kokusabela ukuze kuguqulwe usayizi nokuma kwe-polymer ehlanganisiwe. Ubukhulu bamaketanga e-polymeric bungalawulwa futhi busetshenziswe ngokushintshanisa ukugxila kwe-TBAB.
Isiphetho
Ekuphetheni,I-Tetrabutylammonium bromide (TBAB)iyinhlanganisela eguquguqukayo enezicelo eziningi ezimbonini ezahlukahlukene. Ngokuvamile isetshenziswa njenge-catalyst ku-organic synthesis, ukukhiqizwa koketshezi lwe-ionic, ukuhlaziywa kwamakhemikhali, kanye nokuhlanganiswa kwe-polymer. Izakhiwo zayo eziyingqayizivele, njengokuncibilika okukabili kanye ne-catalysis yokudlulisa isigaba, ziyenza ibe yingxenye ekahle ekuphenduleni kwamakhemikhali nezinqubo ezahlukene.
Sekukonke,I-Tetrabutylammonium bromide TBAB cas 1643-19-2 plays indima ebalulekile embonini yamakhemikhali futhi ibilokhu iyingxenye yokuhlanganiswa kwemikhiqizo ehlukahlukene enomthelela omkhulu ezimpilweni zethu zansuku zonke. Njengoba izinto ezintsha ziqhubeka nokutholwa, i-TBAB izodlala indima ebaluleke kakhulu emkhakheni wamakhemikhali, ezemithi, kanye ne-biotechnology.
