4DescriptionAbstract 13-Vanadomanganate(IV) catalyzed benzoic acid hydrazide oxidation by bromate was studied in sodium acetate-acetic acid buffer solution of pH 4.0. The order in oxidant concentration, substrate and catalyst were found to unity.The accelerating effect of hydrogen ion concentration is due to the prior protonation of the substrate. The initiation of the reaction involves the formation of a complex between catalyst and the protonated form of substrate, hydrazide as evidenced by the occurrence of absorption maxima at 390 nm. The complex thus formed is further oxidized by the oxidant in a rate determining step. Benzoic acid was found to be the oxidation product. Other kinetic data like effect of solvent polarity and the activation parameters determined also supports the proposed mechanism.
