Abstract 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/H 2 O and the other with NaOD/D 2 O. Changes in the cellulose structure were studied by FTIR spectroscopy. Various reactions such as the inclusion of alkali and water in the cellulose lattice, splitting and new formation of inter‐ and intramolecular hydrogen bonds are discussed regarding the absorbance variations and wavenumber shifts of several bands.
