The kinetics of the oxidation by periodate of ethane-1,2-diamine, NN′-dimethylethane-1,2-diamine, and 2-amino-ethanol have been studied at pH 4-12 and 293.2 K. The reaction rates are highest at pH 9-11. It is assumed that periodate monoanion reacts with the unprotonated amines. The reactions of 1,2-diamines with periodate are catalysed by acids and bases. The oxidation of 2-aminoethanol is catalysed by bases, and at high concentration of catalysts the rate seems to approach a limiting value. The pH dependence of the rate of oxidation of these compounds can be explained in terms of multi-stage reactions similar to those in the oxidation of 1,2-diols by periodate.
