Abstract
Alkalicellulose, prepared from wood pulp, was analyzed using CP/MASS 13C NMR. In the alkalicellulose I solid, molecular motion is more rapid than that in the cellulose I solid and there is an intramolecular hydrogen bond between the hydroxyl at C3 and ring oxygen O5′, which is slightly weaker than that for cellulose I. A sodium ion was found to selectively coordinate to the hydroxyl oxygen at the C2 position of the glucose unit.
