Abstract
Complexing agents ethylenediaminetetraacetic acid (EDTA), 2,2'-bipyridyl (bpy), and 1,10-phenanthroline (phen) influence the rate of chromic acid oxidation of 2-propanol in aqueous HClO^sub 4^ solutions. EDTA and bpy catalyse the oxidation rate, whereas phen has no effect, but at higher concentration it acts as an inhibitor. Dependent on conditions, the reactions follow differing order kinetics. In the presence of EDTA and bpy, at the end of the reaction, chromium(III) is present as the EDTA-Cr^sup III^ and bpy-Cr^sup III^ complexes. Probable mechanisms are proposed involving a negatively charged termolecular intermediate complex formed from chromic acid, complexing agent, and 2-propanol.[PUBLICATION ABSTRACT]
