I-polystyrene sulfonic acid CAS:28210-41-5

Uhlobo lwe-acidic lwale nto kanye namakhono okushintshana kwama-ion kwenza kube wusizo ezinhlotsheni ezahlukene zokusebenza. Isetshenziswa kabanzi njenge-catalyst ye-acid eqinile ekwakhiweni kwezinto eziphilayo, ikakhulukazi eku-esterification, e-alkylation, nakwezinye izindlela lapho kudingeka khona i-catalyst enamandla ye-acid. Ukuqina kwayo okuphezulu kokushisa kanye nokumelana namakhemikhali kwenza ifaneleke ukusetshenziswa ezimweni ezinzima zokusabela. Emkhakheni wokwelashwa kwamanzi, ama-resin e-ion-exchange asekelwe ku-polystyrene sulfonic acid asetshenziswa ekususweni kwama-ion ensimbi esindayo kanye nokunye ukungcola emithonjeni yamanzi. Lawa ma-resin ashintshana ngempumelelo ama-ion ensimbi nama-ion e-hydrogen, okwenza kube lula ukuhlanzwa kwamanzi ezindaweni zezimboni kanye nezomasipala. Ngaphezu kwalokho, i-polystyrene sulfonic acid isetshenziswa ekukhiqizweni kwama-membrane e-proton exchange (PEMs) kumaseli kaphethiloli. Lawa ma-membrane enza kube lula ukuthuthwa kwama-proton ngenkathi evimba ukudlula kwamagesi, okwenza abe yizingxenye ezibalulekile kumaseli kaphethiloli e-proton exchange membrane (PEMFCs) asetshenziselwa ukukhiqizwa kwamandla ahlanzekile ezindleleni zamandla ezimoto kanye nezindawo ezimile. Embonini yezemithi, ama-resin e-ion-exchange asekelwe ku-polystyrene sulfonic acid asetshenziselwa ukuhlanza nokwakha izidakamizwa, okusiza ekususeni ukungcola kanye nokukhululwa okulawulwayo kwezithako ezisebenzayo zezemithi (ama-API). Ngaphezu kwalokho, le nto isetshenziswa kumakhemikhali okuhlaziya i-ion chromatography, lapho isebenza khona njengesigaba esimile sokuhlukaniswa nokuhlaziywa kwama-ion kumasampula ahlukahlukene. Sekukonke, izakhiwo ezinamandla ze-acidic ze-polystyrene sulfonic acid, amakhono okushintshana kwama-ion, kanye nokuzinza kokushisa kuyenza ibe yigugu ezisetshenzisweni ezahlukahlukene, kufaka phakathi ukwenziwa kwezinto eziphilayo, ukwelashwa kwamanzi, ubuchwepheshe bamaseli kaphethiloli, imithi, kanye nekhemistri yokuhlaziya, okwenza kube yinto eguquguqukayo eneminikelo ebalulekile ezimbonini ezahlukene.
