D. Fengel et C. Strobel, FTIR SPECTROSCOPIC STUDIES ON THE HETEROGENEOUS TRANSFORMATION OF CELLULOSE-I INTO CELLULOSE-II, Acta polymerica, 45(4), 1994, pp. 319-324
The heterogeneous transformation of cellulose I into cellulose II via
Na-cellulose I was performed by an alkali treatment of cotton linters
followed by stepwise washing.Two experimental series were carried out,
one with NaOH/H2O and the other with NaOD/D2O. Changes in the cellulo
se structure were studied by FTIR spectroscopy. Various reactions such
as the inclusion of alkali and water in the cellulose lattice, splitt
ing and new formation of inter- and intramolecular hydrogen bonds are
discussed regarding the absorbance variations and wavenumber shifts of
several bands.
