KINETIC STUDIES OF OXIDATION OF GLYCEROL, 1, 2- PROPANE DIOL BY HEXAVALENT CHROMIUM IN AQUEOUS ACETIC ACID – PERCHLORIC ACID MEDIA

Author: M.L.N. GOPAL., N. MADHAVI, P.S. RADHAKRISHNA MURTI
Abstract: Kinetics of oxidation of diols (glycerol and 1, 2-propanediol) by hexavalent chromium was studied in aqueous acetic acid perchlolric acid mixtures. The reactions were first order with respect to oxidant and substrate concentrations.Whereas, reaction showed second order by varying acid concentration. With the change in the concentration of manganous ion and solvent composition change in the rate of reaction was observed. In these oxidation reactions an increase in rate was observed with decrease in dielectric constant pointing to the fact that these are reactions between positive ion and dipolar. Arrhenius parameters were computed and a plausible mechanism was postulated based on experimental results.
Keyword: Glycerol, 1, 2-Propanediol, Chromium (VI), Acetic acid medium, Oxidation, Kinetics.
