Periodate oxidation of cellulose - a complete kinetic study

Creator:: Chandan, Bhaskar Arjundev
Abstract:: The effect of over-oxidation on periodate oxidation of cellulose was studied. It was found that the over-oxidation process has a significant effect on the overall reaction. An integrated rate equation was formulated. The oxidation of internal glucose units is second-order overall, first order with respect to both periodate and cellulose;...
