Abstract
The relative partial pressures of acetylacetone above mixed aqueous-organic solutions were measured chromatographically and the Gibbs energies of acetylacetone transfer from water to the mixed solvents were determined and separated into contributions from the keto and enol forms. The tautomerization equilibrium was related to other thermodynamic equilibria and the Gibbs energy of transfer of the keto form was correlated with that of acetone.
