The kinetics of oxidation of 2-aminoethanol and 3-amino-1-propanol by diperiodatoargentate(III) (DPA) were carried out spectrophotometrically in alkaline medium in the temperature range of 293.2-308.2 K. The reaction showed first order with respect to [DPA] and each reductant. The observed rate constant (k obs ) decreased with the increase of [IO 4 -] and increased with the increase of [OH -]. Increasing ionic strength of the medium decreased the rate. Investigations of the reaction at different temperatures allowed the determination of the activation parameters for the slow step of proposed mechanism. The proposed mechanism and the derived rate laws found consistent with the observed kinetics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
