Imikhiqizo

I-sodium trifluoroacetate (NaCF3CO2) iyinhlanganisela yamakhemikhali evame ukusetshenziswa ezindaweni ezihlukahlukene zezimboni nezaselabhorethri ngenxa yezakhiwo zayo ezihlukile.Kuwuketshezi oluyikristalu olumhlophe oluncibilika kakhulu emanzini nasezincibilini zemvelo ezishisayo.Okunye ukusetshenziswa okuyinhloko kwe-sodium trifluoroacetate iyi-reagent ku-organic synthesis.Ingasetshenziswa 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-sodium trifluoroacetate ingasetshenziswa, isibonelo, ku-acylation yama-amines, i-alcohol, ne-thiols, okuholela ekwakhekeni kweziphakathi ezibalulekile noma imikhiqizo yokugcina.Ngaphezu kwalokho, i-sodium trifluoroacetate ivame ukusetshenziswa ekuhlanganiseni kwezinhlanganisela ze-fluorinated.Ukwethulwa kwama-athomu e-fluorine kuma-athomu e-organic kungathuthukisa izici zabo zomzimba namakhemikhali, njengokukhuphuka kwe-lipophilicity, ukuzinza, kanye nomsebenzi webhayoloji.I-sodium trifluoroacetate isebenza njengesandulela esibalulekile sokuhlanganiswa kwamaqembu e-trifluoroacetyl kumakhemikhali e-organic, okuvumela ukuhlanganiswa kwemithi ye-fluorinated pharmaceuticals, agrochemicals, nama-polymers. .Ingasebenza njenge-Lewis acid catalyst, ikhuthaze izinguquko ezihlukahlukene ezifana ne-Friedel-Crafts acylation kanye nokusabela kwe-aldol condensation.Ikhono layo lokuvula ama-substrates athile kanye nokwenza lula izindlela zokusabela kuyenza ibe ithuluzi elibalulekile kumakhemikhali okwenziwa.Ngaphezu kwalokho, i-sodium trifluoroacetate ithola izinhlelo zokusebenza kwezinye izindawo ezifana namakhemikhali okuhlaziya.Ingasetshenziswa njengesethenjwa esijwayelekile se-nuclear magnetic resonance (NMR) spectroscopy.I-sodium trifluoroacetate ineziqongo ze-NMR ezichazwe kahle, okuyenza isebenziseke ekulinganiseni amathuluzi e-NMR nokuhlola ukusebenza kwawo.Kafushane, i-sodium trifluoroacetate iyinhlanganisela eguquguqukayo enokusetshenziswa okuhlukahlukene ekuhlanganiseni kwe-organic, ukusabela kwe-fluorination, kanye ne-catalysis.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 igqamisa ukusetshenziswa kwayo kuzilungiselelo zaselabhorethri ezahlukene.
