Potassium trifluoroacetate Usage And Synthesis

Chemical Properties

white crystalline powder

Uses

It is a reagent for preparation of aryl trifluoromethyl sulfides, by heating with the diaryl disulfide.

Flammability and Explosibility

Non flammable

Purification Methods

To purify it, dissolve the salt in trifluoroacetic acid with ca 2% of trifluoroacetic anhydride, filter it and evaporate it carefully to dryness (avoid over heating), and finally dry it in a vacuum at 100o. It can be recrystallised from trifluoroacetic acid (solubility in the acid is ca 50.1%).
