Potassium trifluoroacetate

Potassium trifluoroacetate is the trifluoroacetate salt of potassium, with the chemical formula CF3COOK. It can form an acid salt KH(CF3COO)2.

Preparation and properties
Potassium trifluoroacetate can be obtained by reacting trifluoroacetic acid with potassium hydroxide, potassium carbonate or potassium bicarbonate.


 * CF3COOH + KOH → CF3COOK + H2O

It can decompose when heated and reaches the maximum decomposition rate at 220 °C. The products are potassium fluoride and some volatile products, such as carbon dioxide, carbon monoxide, trifluoroacetyl fluoride, etc.
