The equilibrium between the keto and enol tautomers of acetylacetone, trifluoroacetylacetone and hexafluoroacetylacetone in the neat liquid state and dissolved in supercritical fluid carbon dioxide have been studied, as a function of pressure and temperature, by 1H NMR. This allows determination of the thermodynamic parameters, ΔH and ΔS, for the keto-enol equilibrium. The observed trends are well correlated with extraction results for this class of compounds.
