Notes:
Cotton cellulose is decrystallized by periodate oxidation to essentially zero crystallinity index (CI) at 100% oxidant consumption. The decrease in CI is pseudo zero-order over 60% of the reaction and consistent with a diffusion-controlled mechanism. The attack on regions of high order is indicated to be 100% in the latter phase of oxidation and 13% in the initial phase. Data allow an estimate that approximately 60% of the structural segments of the cotton cellulose under investigation lies in highly ordered arrangements.
