Perfluoropropionic acid (PFPrA[2]) or pentafluoropropionic acid is the perfluoroalkyl carboxylic acid with the formula CF3CF2CO2H. It is a colorless liquid that is strongly acidic and soluble in water and polar organic solvents.
A convenient, safe method for generating tetrafluoroethylene is the pyrolysis of the sodium salt of pentafluoropropionic acid:[3]
- C2F5CO2Na → C2F4 + CO2 + NaF
