Iimveliso

I-Trifluoromethanesulfonic acid (CF3SO3H), eyaziwa ngokuba yi-triflic acid, yi-asidi esebenzayo kakhulu kwaye eyomeleleyo efumana ukusetyenziswa okubanzi kwiinkqubo ezahlukeneyo zemichiza kunye namashishini.Isetyenziswa ngokubanzi njenge-catalyst, i-solvent, kunye ne-reagent ngenxa ye-acidity ekhethekileyo kunye neempawu ezizodwa.Enye yezicelo eziphambili ze-trifluoromethanesulfonic acid njenge-superacid catalyst.Ithathwa njengenye yezona acid zinamandla ze-Brønsted ezaziwa, idlula i-sulfuric, i-hydrochloric, kunye ne-fluorosulfuric acid ngokwe-acidity.Le acidity imangalisayo ivumela i-triflic acid ukuba ikhuphe iimpendulo ezahlukeneyo ezifuna iimeko zeasidi ezomeleleyo, kubandakanya i-esterification, i-acylation, i-alkylations, kunye nohlengahlengiso.Ibaluleke kakhulu ekukhuthazeni ukusabela okubandakanya i-carbocations, njengoko izinza kwaye iphucula i-reactivity yabo.I-asidi ye-Triflic ikwasetyenziswa njengesinyibilikisi kwiimpendulo ezithile, ngakumbi ezo zifuna iindawo ezine-acidic kakhulu.Inokunyibilikisa uluhlu olubanzi lweekhompawundi eziphilayo kunye ne-inorganic, iyenza ibe luncedo kwiimpendulo ezibandakanya i-polar kunye ne-nonpolar solutes.Ukongeza, ubume bayo obuqinileyo bunokuphucula ukunyibilika kunye nokunceda kwi-reaction kinetics.Olunye usetyenziso olubalulekileyo lwe-trifluoromethanesulfonic acid kukuveliswa kwee-triflates.I-asidi ye-Triflic inokusabela kunye ne-alcohols, i-amines, kunye nezinye i-nucleophiles ukwenza i-triflates yazo ehambelanayo (CF3SO3-), ezizinzile kakhulu kunye namaqela asebenzayo asebenzayo.I-Triflates inokusebenza njengamaqela ashiyayo afanelekileyo okanye isebenze i-nucleophiles, ivumela ukuba kubekho iindlela ezahlukeneyo zokuphendula ezilandelayo ezifana nokutshintshwa kwe-nucleophilic, ukulungiswa kwakhona, kunye ne-carbon-carbon bond formations.Ngaphezu koko, i-triflic acid inezicelo kwi-synthesis of pharmaceuticals, agrochemicals, kunye neekhemikhali ezikhethekileyo.I-reactivity yayo ekhethekileyo kunye ne-asidi iyenza i-reagent exabisekileyo ekubunjweni kwee-molecule ze-organic complex.Ukongezelela, inokubonisa i-reactivity ekhethiweyo, eyenza ukuba ijolise kumaqela athile asebenzayo okanye izikhundla kwi-molecule, iququzelele ukuhlanganiswa kwee-isomers ezithile okanye i-enantiomers.Kubalulekile ukuba uqaphele ukuba i-trifluoromethanesulfonic acid kufuneka iphathwe ngononophelo olukhulu ngenxa yendalo yayo eyingozi kakhulu. .Ukhuseleko olufanelekileyo, kubandakanywa nokusetyenziswa kwezixhobo zokukhusela kunye nokusebenza phantsi kwe-ventilation efanelekileyo, kufuneka ilandelwe ukunciphisa ingozi.Ngokufutshane, i-trifluoromethanesulfonic acid i-asidi enamandla kunye nezicelo ezahlukeneyo kwiinkqubo zeekhemikhali kunye namashishini.Ubumuncu bayo obunamandla buyenza ikwazi ukwenza uluhlu olubanzi lweempendulo, isebenze njengesinyibilikisi, kwaye ithathe inxaxheba ekusekweni kwamaqela asebenzayo azinzileyo.Ukuguquguquka kwayo kunye nokusebenza kwakhona kuyenza i-reagent eyimfuneko ekudityanisweni kweemolekyuli zezinto eziphilayo.Nangona kunjalo, kufuneka kulumke xa uphatha i-triflic acid, ngokubambelela kwiiprothokholi zokhuseleko ezifanelekileyo ukuqinisekisa impilo-ntle yekhemisti kunye nokuthintela iingozi.
