Production

The salts containing the trifluoroacetate anion can be made by an acid–base reaction between trifluoroacetic acid and a base, such as sodium hydroxide (NaOH) to give sodium trifluoroacetate (CF3COONa):

CF3CO2H + NaOH ⟶ CF3CO2Na + H2O

Trifluoroacetate as a PFAS

Trifluoroacetic acid is one of the shortest possible perfluoroalkyl substances (PFAS). It is suspected to be a persistent pollutant.[1][2]
