Abstract  

The fraction of labile hydrogens to total hydrogen atoms in cellulose isolated from a pine tree was found to be 10–11%. Most labile hydrogens in hydroxy groups of the cellulose could be eliminated within 6 h by heat treatment at 110°C with CuO in a flow of gas containing oxygen, due to dehydration of cellulose by interaction with oxygen which was accelerated by the presence of CuO. The contaminating effect of labile hydrogens on the measurement of tritium preserved in cellulose may thus be disregarded when such heat treatment is performed.
