| Abstract: | The keto-enol tautomerism of dibenzoylmethane (I) in organized media, e.g. b-cyclodextrin and micelles (ionic and non-ionic), was monitored by UV absorption spectra. The introduction of b-cyclodextrin or the formation of micelle in the aqueous solution of I made the tautomerism equilibrium favor for enol type. The results indicated that the properties of tautomerism of I could be applied to characterize the microenvironmental property of organized media, reveal the structural characteristics of micelle, and determine the crit. micelle concentration of surfactant. |
