I-Tetrabutylammonium iodide (TBAI)uye wavela njengomdlali oyinhloko emikhakheni ehlukahlukene ye-chemistry, kusukela ku-catalysis kuya kwisayensi yezinto ezibonakalayo.Kulokhu okuthunyelwe kwebhulogi, singena ekusetshenzisweni okuhlukahlukene kwe-TBAI, sihlola indima yayo njengesisusa ekuguqulweni kwezinto eziphilayo kanye negalelo layo ekuthuthukisweni kwezinto ezintsha.Hlanganyela nathi njengoba sembula ukuguquguquka okuyingqayizivele kwale nhlanganisela ethakazelisayo.
I-Tetrabutylammonium iodide, enefomula yamakhemikhali (C4H9)4NI, iwusawoti we-quaternary ammonium ovame ukusetshenziswa njengesandulela ekuhlanganiseni kwezinhlanganisela eziphilayo.Kuyisiqinile esingenambala noma esimhlophe esincibilika kakhulu kuzincibilikisi ze-polar njengamanzi notshwala.I-TBAI inohlu olubanzi lwezinhlelo zokusebenza, futhi ukuguquguquka kwayo kubangelwa ikhono layo lokusebenza njenge-catalyst ekuphenduleni kwamakhemikhali okuhlukahlukene.
Enye yezinhlelo eziphawuleka kakhulu ze-TBAI ukusetshenziswa kwayo njengesisusa sokudlulisa isigaba ekuguqulweni kwezinto eziphilayo.I-Phase-transfer catalysis (PTC) iwubuchule elenza kube lula ukudluliswa kwama-reactants phakathi kwezigaba ezingahlangani, njengezigaba eziphilayo kanye nezamanzi.I-TBAI, njenge-phase-transfer catalyst, isiza ukukhulisa izinga lokusabela futhi ithuthukise isivuno semikhiqizo oyifunayo.Ikhuthaza ukusabela okufana nokushintshwa kwe-nucleophilic, i-alkylations, kanye ne-dehydrohalogenations, okuvumela ukuhlanganiswa kwama-molecule e-organic eyinkimbinkimbi ngokusebenza kahle okuphezulu.
Ngokungeziwe ku-catalysis, i-TBAI iphinde yathola izinhlelo zokusebenza kusayensi yezinto ezibonakalayo.Ingasetshenziswa njengesifanekiso noma i-ejenti yokuqondisa isakhiwo ekuhlanganiseni izinto ezinoveli.Isibonelo, i-TBAI iye yaqashwa ekulungiseleleni izinhlobo ezihlukahlukene zama-zeolite, okuyizinto ezinama-porous ezinezakhiwo ezichazwe kahle.Ngokulawula izimo zokusabela, i-TBAI ingaqondisa ukukhula kwamakristalu e-zeolite, okuholela ekwakhekeni kwezinto ezinezakhiwo ezifiselekayo njengendawo ephezulu, usayizi wezimbotshana olawulwayo, nokuzinza okushisayo.
Ngaphezu kwalokho, i-TBAI iye yasetshenziswa ekwenziweni kwezinto ezixubile, lapho isebenza khona njengesixhumanisi noma ukuqinisa phakathi kwezingxenye ezahlukene.Lezi zinto ezixubile zivame ukubonisa izakhiwo ezithuthukisiwe zemishini, ezibonakalayo, noma zikagesi uma kuqhathaniswa nezingxenye zazo ngazinye.I-TBAI ingakha amabhondi okuxhumana aqinile nama-ion ensimbi noma ezinye izingxenye zemvelo, okuvumela ukuhlangana kwezinto ezisebenza ngokuhambisanayo.Lezi zinto zokusebenza zinokusebenza okungenzeka ezindaweni ezinjengezinzwa, ukugcinwa kwamandla, kanye ne-catalysis.
Ukuguquguquka kwe-TBAI kudlulela ngale kokusetshenziswa kwayo okuqondile ku-catalysis nesayensi yezinto ezibonakalayo.Ibuye isetshenziswe njenge-electrolyte esekelayo ezinhlelweni ze-electrochemical, njenge-solvent ye-organic reactions, nanjenge-ejenti ye-doping ekuhlanganiseni kwama-polymers conductive.Izakhiwo zayo eziyingqayizivele, njengokuncibilika okuphezulu, i-viscosity ephansi, kanye ne-ion conductivity enhle, ikwenza kube ukukhetha okufanele kulezi zinhlelo zokusebenza ezihlukahlukene.
Ekuphetheni,I-Tetrabutylammonium iodide (TBAI)iyinhlanganisela ethole usizo oluphawulekayo emkhakheni we-catalysis kanye nesayensi yezinto ezibonakalayo.Ikhono layo lokusebenza njenge-catalyst ekuguqulweni kwezinto eziphilayo kanye negalelo layo ekuthuthukisweni kwezinto ezintsha kuyenza ibe ithuluzi eliyigugu kosokhemisi nososayensi bezinto ezibonakalayo ngokufanayo.Njengoba abacwaningi beqhubeka nokuhlola amandla e-TBAI, singalindela ukubona intuthuko eyengeziwe emikhakheni ehlukahlukene ye-chemistry nesayensi yezinto ezibonakalayo.
