Abstract
Kinetics and mechanism of the disproportionation of MnO~4~^−^ via [CMC—Mn^VI^O~4~^2−^] intermediate complex formation during the oxidation of carboxymethyl cellulose (CMC) polysaccharide have been investigated spectrophotometrically at pH ≥12 and various temperatures (15–35^°^C). The rate law was suggested as Rate = k~obs~MnO~4~^−^]. Kinetic and spectrophotometric measurements revealed the formation of hypomanganate(V) and manganate(VI) transient species, which are base‐catalyzed. A mechanism was postulated that is consistent with the experimental data. © 2001 John Wiley & Sons, Inc. Int J Chem Kinet 33: 605–611, 2001
