The kinetics of keto-enol tautomerization of acetylacetone was studied in mixed aqueous media by u.v. and NMR spectrometries. As an organic component, aprotic (dioxane and acetonitrile) and protic (methanol, ethanol and t-butanol) solvents were used. The tautomerization reaction was initiated by ...
