RECRYSTALLIZATION BEHAVIOR OF CELLULOSE AND LIGNOCELLULOSE FROM PINUS-MASSONIANA

In an X-ray diffraction investigation, the recrystallization behavior of ball-milled Chinese southern pine wood was found to differ from tha t of cellulose. The crystallinity of lipocellulose milled for a very l ong time and recrystallized by wetting in water did not decrease with increasing milling time as was the case with milled cellulose. In addi tion, it appeared that the presence of lipin tended to restrict the am orphous cellulose produced by milling from recrystallizing into Cellul ose II, whereas it had no influence on the recrystallization into Cell ulose I. These results were discussed in the context of the mechanism of the conversion of Cellulose I to Cellulose II.
