Abstract
The structural directivity of the phosphorylation of cellulose by poly phosphoric acid within the pyranose ring was studied by esterification of a partially substituted ester by methanesulfonyl chloride. The pro cess occurred predominantly at the primary alcoholic groups in the cel lulose macromolecule, and in this case the degree of substitution vari ed from gamma = 0.3-0.6.
