The solution behavior of thenoyltrifluoroacetone (TTA) has been investigated in a series of higher alcohols which are often used in solvent extraction by means of UV and NMR spectrometries. It was experimentally confirmed that TTA exists in the enol and hemiacetal forms in dehydrated alcohol, while in wet alcohol we should also take a hydrate form into consideration. The fractions of the species at equilibrium were determined, and their dependencies on the water concentration and on the solvent properties, <I>i.e.</I>, the dielectric constant and the solubility parameter, were examined. The interconversion rate between the enol and hemiacetal forms were also observed as a function of the water concentration.
