I-Potassium trifluoroacetate (KCF3CO2) iyinhlanganisela yamakhemikhali eyabelana ngezakhiwo nezindlela zokusebenza ezifanayo nozakwabo we-sodium, i-sodium trifluoroacetate.Kuyikristalu emhlophe eqinile encibilika kakhulu emanzini nasezincibilikisini zemvelo ezitholakala ezindaweni ezishisayo.I-Potassium trifluoroacetate ivame ukusetshenziswa ezimweni ezihlukahlukene zezimboni nezaselabhorethri ngenxa yezindawo zayo eziyingqayizivele.Okunye ukusetshenziswa okuyinhloko kwe-potassium trifluoroacetate iyi-reagent ku-organic synthesis.Ingasebenza njengomthombo weqembu le-trifluoroacetyl (-COCF3) ekuphenduleni okuhlukahlukene.Iqembu le-trifluoroacetyl laziwa ngobunjalo balo bokuhoxiswa kwe-electron kanye nokuzinza, okulenza libe usizo ekuhlanganisweni kwemithi, amakhemikhali ezolimo, namanye amakhemikhali amahle.I-Potassium trifluoroacetate ingasetshenziswa njenge-reagent ekuphenduleni kwe-acylation, lapho isiza khona ukwethula iqembu le-trifluoroacetyl kuma-amine, utshwala, i-thiols, namanye ama-nucleophilic compounds. .Ingasebenza njenge-Lewis acid catalyst, ikhuthaze izinguquko ezihlukahlukene ezifana ne-Friedel-Crafts acylation kanye nokusabela kwe-aldol condensation.Ikhono layo lokucupha ama-substrates athile kanye nokwenza lula izindlela zokusabela kwenza kube ithuluzi elibalulekile kumakhemikhali okwenziwa.Ngaphezu kwalokho, i-potassium trifluoroacetate ithola izinhlelo zokusebenza kwezinye izimboni nezinkambu zocwaningo.Isetshenziswa kabanzi emkhakheni wekhemikhali yokuhlaziya, ikakhulukazi ku-spectroscopy ye-nuclear magnetic resonance (NMR).Njenge-sodium trifluoroacetate, i-potassium trifluoroacetate ineziqongo ze-NMR ezichazwe kahle, okuyenza ibe inkomba ewusizo evamile yokulinganisa amathuluzi e-NMR nokuhlola ukusebenza kwawo.I-Potassium trifluoroacetate iphinde isetshenziswe emkhakheni wekhemistri ye-polymer.Ingasetshenziswa njenge-monomer esebenzayo ekuhlanganiseni kwama-polymers ane-fluorinated.Ukufaka amaqembu e-trifluoroacetyl kumaketanga e-polymer kunganikeza ukumelana kwamakhemikhali okuthuthukisiwe, ukuzinza okushisayo, kanye ne-hydrophobicity kuma-polymers avelayo.Lawa ma-polymers ane-fluorinated athola izinhlelo zokusebenza ezimbonini ezihlukahlukene, okuhlanganisa okokumboza, ulwelwesi, kanye ne-electronics.Kafushane, i-potassium trifluoroacetate iyinhlanganisela eguquguqukayo enokusetshenziswa okuhlukahlukene ku-organic synthesis, catalysis, chemistry analytical, kanye ne-polymer chemistry.Ikhono layo lokusebenza njengomthombo weqembu le-trifluoroacetyl nokuzinza kwalo kuyenza i-reagent ebalulekile yokuhlanganiswa kwemithi, amakhemikhali e-agrochemicals, namanye amakhemikhali amahle.Ukwengeza, indima yayo njenge-catalyst kanye nokusebenza kwayo kukhemistri yokuhlaziya kanye ne-polymer synthesis igqamisa ukusetshenziswa kwayo kuzilungiselelo ezihlukene zezimboni nezocwaningo.
