Incazelo emfushane:

I-Trifluoromethanesulfonic acid, i-asidi ephilayo enamandla enefomula CF3SO3H, encibilika emanzini, ubuthi obuphansi. Isetshenziswa kabanzi, ingenye yama-superacids aziwayo. Inokugqwala okuqinile nokumuncwa komswakama, futhi isetshenziswa kabanzi embonini yezemithi, yamakhemikhali nezinye, enemithamo emincane, i-asidi eqinile kanye nemvelo ezinzile. Ezikhathini eziningi, ingangena esikhundleni se-sulfuric acid yendabuko, i-hydrochloric acid namanye ama-asidi endabuko e-inorganic, futhi ibambe iqhaza ekwandiseni nasekuthuthukiseni inqubo.

I-Trifluoromethanesulfonic anhydride, eyaziwa nangokuthi i-triflic anhydride, iyinhlanganisela yamakhemikhali enefomula₂O.

Yi-acid anhydride etholakala ku-triflic acid.

Le nhlanganisela iyi-electrophile eqinile, ewusizo ekwethuleni iqembu le-triflyl, i-CF₃SO₂.

Isicelo

Izinhlelo zokusebenza

1. Njengesiphakathi, i-Trifluoromethanesulfonic anhydride isetshenziswa kakhulu embonini yezemithi, amaprotheni, ushukela, amavithamini, njll., ama-Friedel-Crafts ama-catalysts we-benzylation kanye nokusabela kwe-cyclohexylation.

2. Imboni yepulasitiki isetshenziselwa ukuvuselela ukusabela kokuhlanganiswa kwamakhemikhali njenge-catalyst ye-oligomerization kanye nokuguqulwa kwerabha ye-silicon yerabha ye-Chemicalbook.

3. Imboni yamakhemikhali kagesi yokukhiqiza ama-polymers asebenza ngogesi

4. Imboni yamafutha njenge-catalyst ye-protonation reaction.

5. I-synthetic herbicide kanye nokulawula ukukhula kwemboni ye-agrochemical.

6. Embonini kashukela.

7. Izifundo zaselabhorethri zisetshenziselwa ukusabela okuthile

Isevisi esingayinikeza

1) Inkontileka esemthethweni ingasayinwa

2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa

3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa

Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
