Abstract
The adsorption on regenerated cellulose of water at vapor pressures of 0 to 40 μ Hg has been measured by an oxygen-18 dilution technique. The results showed that cellulose may be dried to less than 0.04% moisture by evacuation at 70 °C. The adsorption isotherm was compared with that of Taylor for viscose rayon.It was also shown that oxygen-18 does not exchange between cellulose and water.Keywords
