Specific Volume of Native Cellulose

Abstract

Specific-volume measurements of native cellulose determined in different media and calculated from x-ray data are compared. Data for the specific volume of cellulose containing different amounts of water measured in a benzene medium are analyzed. On the assumption that the differ ence between the specific volumes measured in benzene and the specific volume calculated from x-ray data is due to voids, and that the differences between the x-ray value and the values deter mined in water are due to the compacting of water, reasonable compression values are obtained that are in accord with the concept of hydrogen bonding of water and other findings.
