Potassium trifluoroacetate is the

trifluoroacetate salt of potassium, with the chemical formula CF3COOK. It can form an acid salt KH(CF3COO)2.[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.[3]
