Ingabe i-TBAB inobuthi?

I-Tetrabutylammonium bromide (TBAB),I-MF yi-C16H36BrN, iwusawoti we-quaternary ammonium. Ngokuvamile isetshenziswa njenge-catalyst yokudlulisa isigaba kanye ne-organic synthesis. I-TBAB iyimpushana emhlophe ecwebezelayo enenombolo ye-CAS 1643-19-2. Ngenxa yezakhiwo zayo eziyingqayizivele, i-reagent ebalulekile ekuphenduleni kwamakhemikhali okuhlukahlukene. Umbuzo ojwayelekile mayelana ne-TBAB ukuncibilika kwayo emanzini. Ukwengeza, kuvame ukukhathazeka ngokuthi ingabe i-TBAB inobuthi? Kulesi sihloko, sizohlola ukunyibilika kwe-TBAB emanzini futhi ingabe i-TBAB inobuthi?

Okokuqala, ake sibhekane nokuncibilika kwe-TBAB emanzini.I-Tetrabutylammonium bromideiyancibilika kancane emanzini. Ngenxa yemvelo yayo ye-hydrophobic, inokuncibilika okuphansi kuzincibilikisi ze-polar, kuhlanganise namanzi. Kodwa-ke, i-TBAB incibilika kakhulu kuzincibilikisi zemvelo njenge-acetone, i-ethanol, ne-methanol. Lesi sakhiwo sikwenza kube inhlanganisela ebalulekile ekuhlanganiseni kwe-organic kanye nezinqubo ezihlukahlukene zamakhemikhali ezidinga ama-catalysts okudlulisa isigaba.

I-TBABisetshenziswa kabanzi njenge-catalyst yokudlulisa isigaba ku-organic chemistry, isiza ukudlulisa ama-reactants kusuka kwesinye isigaba kuya kwesinye. Ikhuthaza ukusabela phakathi kwama-reactants angabonakali ngokudlulisela ama-ion noma ama-molecule ukusuka kwesinye isigaba ukuya kwesinye, ngaleyo ndlela kwandise amazinga okusabela kanye nesivuno. Ngaphezu kwalokho, i-TBAB ingasetshenziswa futhi ekuhlanganiseni izidakamizwa, amakhemikhali ezolimo namanye amakhemikhali amahle. Ikhono layo lokwandisa ukusebenza kahle kokusabela kanye nokukhetha kuyenza ibe ithuluzi elibalulekile lokukhiqizwa kwezinhlobonhlobo zezinhlanganisela.

Manje, ake sikhulumeI-TBABezinobuthi? I-Tetrabutylammonium bromide ithathwa njengobuthi uma ingenwa, ihogelwa, noma ithinta isikhumba. Kubalulekile ukuphatha lesi sithako ngokucophelela futhi ulandele izinyathelo zokuphepha ezifanele uma usisebenzisa. Ukuhogela umoya kwe-TBAB kungabangela ukucasuka kwemigudu yokuphefumula, futhi ukuthintana kwesikhumba kungase kubangele ukucasuka kanye ne-dermatitis. Ukungena kwe-TBAB kungabangela ukucasuka kwamathumbu kanye neminye imiphumela emibi. Ngakho-ke, ukusetshenziswa kwezinto ezifanele zokuzivikela (isb, amagilavu ​​namajazi elebhu) kubalulekile lapho uphatha i-TBAB.

Ngaphezu kwalokho,I-TBABkufanele ilahlwe ngokuhambisana nemithetho kanye nemihlahlandlela yendawo yemfucuza eyingozi. Izindlela ezifanele zokuphatha kanye nokulahla kufanele zilandelwe ukuze kuvinjelwe ukungcoliswa kwemvelo kanye nokulimala okungaba khona empilweni yabantu.

Ngokufigqiwe,I-tetrabutylammonium bromide (TBAB)iyancibilika kancane emanzini kodwa incibilika kalula kuzincibilikisi zemvelo, okuyenza ibe isakhi esibalulekile ku-organic synthesis kanye ne-phase transfer catalysis. Ukusetshenziswa kwayo kumakhemikhali aphilayo, ukuhlanganiswa kwezidakamizwa nezinye izinqubo zamakhemikhali kugqamisa ukubaluleka kwayo emkhakheni wokucwaninga nokukhiqiza amakhemikhali. Kodwa-ke, kubalulekile ukuqaphela ubuthi obungaba khona be-TBAB futhi uthathe izinyathelo zokuphepha ezidingekayo lapho uphatha futhi ulahla le nhlanganisela. Ukubambelela ezimisweni zokuphepha nemihlahlandlela kubalulekile ekuqinisekiseni ukusetshenziswa okuphephile kwe-TBAB kanye nokunciphisa noma yiziphi izingozi ezihlobene.
