Boiling point of trifluoroacetic acid

WebThe pH of a trifluoroacetic acid aqueous solution at 10% (w/w) is 0.45 and the measure of the alkali reserve is 35 g NaOH/g substance. Following the pH-acid/alkali reserve method, the classification as corrosive is predicted for TFA.

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 inhaled, causes severe skin burns and is toxic for aquatic organisms even at low concentrations.

SAFETY DATA SHEET - Fisher Sci

WebTrifluoroacetic acid (TFA) is the most practical perfluoro organic acid. Strong acidity, a substantial dielectric constant, miscibility with water and most organic solvents, and a relatively low boiling point are its distinguishing characteristics (71.8 degree Celsius). WebBasicity. With a pK a of 0.23 for trifluoroacetic acid, the trifluoroacetate ion is an extremely weak base compared to acetic acid, which has a pK a of 4.76. This is due to the electron-withdrawing effect of the three fluorine atoms adjacent the carboxylate group.Strong acids such as hydrochloric acid or sulfuric acid can protonate the trifluoroacetate ion to …
