O le trifluoromethanesulfonic acid (CF3SO3H), e masani ona taʻua o le triflic acid, o se vailaʻau sili ona malosi ma malosi e maua ai le faʻaogaina tele i gaioiga faʻasolosolo ma alamanuia eseese.O loʻo faʻaaogaina lautele e avea o se faʻamalosi, solvent, ma reagent ona o lona tulaga faʻapitoa ma mea faʻapitoa. O se tasi o faʻaoga muamua o le trifluoromethanesulfonic acid e pei o le superacid catalyst.O lo'o ta'ua o se tasi o vaila'au sili ona malosi Brønsted ua iloa, e sili atu le sulfuric, hydrochloric, ma e o'o lava i le fluorosulfuric acid i tulaga o le acidity.O lenei acidity mataʻina e mafai ai e le triflic acid ona faʻapipiʻiina gaioiga eseese e manaʻomia ai tulaga malosi malosi, e aofia ai le esterification, acylation, alkylations, ma toe faʻatulagaina.E taua tele mo le faʻalauiloaina o gaioiga e aofia ai carbocations, aua e faʻamautu ma faʻaleleia ai lo latou gaioiga.Triflic acid o loʻo faʻaaogaina foi e avea o se solvent mo nisi gaioiga, aemaise lava i latou e manaʻomia ai siosiomaga maualuga.E mafai ona fa'amavaeina le tele o mea fa'aola ma mea fa'aletino, ma fa'aaogaina mo gaioiga e aofia ai solute polar ma nonpolar.E le gata i lea, o lona natura malosi malosi e mafai ona faʻaleleia atili ai le solubility ma fesoasoani i le kinetics tali.O le isi faʻaoga taua o le trifluoromethanesulfonic acid o loʻo i le gaosiga o triflates.Triflic acid e mafai ona tali atu i ava malosi, amine, ma isi nucleophiles e fausia ai a latou triflates tutusa (CF3SO3-), o vaega sili ona mautu ma felagolagomai.Triflates e mafai ona avea o ni vaega lelei o le tuua pe faʻagaoioia nucleophiles, e mafai ai le tele o gaioiga mulimuli ane e pei o le nucleophilic substitutions, rearrangements, ma carbon-carbon bond formations. E le gata i lea, o le triflic acid o loʻo i ai faʻaoga i le tuʻufaʻatasiga o vailaʻau, agrochemicals, ma vailaʻau faʻapitoa.O lona fa'agaoioiga tulaga ese ma le fa'asa'o e avea ai ma mea taua mo le fa'avaeina o molela'au fa'aola lavelave.E le gata i lea, e mafai ona faʻaalia le gaioiga filifilia, e mafai ai ona faʻatatau i vaega faʻapitoa poʻo tulaga i totonu o se mole, faʻafaigofie le faʻaogaina o isomers poʻo enantiomers faapitoa. .O puipuiga lelei o le saogalemu, e aofia ai le faʻaogaina o meafaigaluega puipuia ma galue i lalo o le ea talafeagai, e tatau ona mulimulitaʻia e faʻaitiitia ai aʻafiaga.O lona malosi malosi malosi e mafai ai ona faʻapipiʻiina le tele o tali, galue e pei o se solvent, ma auai i le faʻavaeina o vaega galue mautu.O lona agava'a ma le fa'agaoioiga ua avea ai ma mea e mana'omia mo le tu'ufa'atasiga o molela'au fa'aola lavelave.Ae ui i lea, e tatau ona faʻaeteete pe a faʻaaogaina le triflic acid, tausisi i tulafono saogalemu e mautinoa ai le soifua manuia o le fomaʻi ma puipuia ai faʻalavelave.
