WebAcetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air. TFA is prepared industrially by the electrofluorination of acetyl chloride or acetic anhydride, followed by hydrolysis of the resulting trifluoroacetyl fluoride: CH 3COCl + 4 HF → CF 3COF + 3 H 2 + HCl CF 3COF + H 2O → CF 3COOH + HF Where desired, this compound may be dried by addition of trifluoroacetic … See more Trifluoroacetic acid (TFA) is an organofluorine compound with the chemical formula CF3CO2H. It is a structural analogue of acetic acid with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms … See more TFA is the precursor to many other fluorinated compounds such as trifluoroacetic anhydride, trifluoroperacetic acid, … See more TFA was claimed to occur naturally in sea water, but only in small concentrations at about 200 ng per liter. However, a review paper from 2024 concludes that there is insufficient evidence that TFA occurs naturally, especially without a reasonable mechanism of … See more Trifluoroacetic acid is a corrosive acid but it does not pose the hazards associated with hydrofluoric acid because the carbon-fluorine bond is not labile. Only if heated or treated with ultrasonic waves will it decompose into hydrofluoric acid. TFA is harmful when … See more • Fluoroacetic acid – highly toxic but naturally occurring rodenticide CH2FCOOH • Difluoroacetic acid • Trichloroacetic acid, the chlorinated analog See more
