The effect of the rotation frequency was investigated in a range from 450650 min − results are presented in Fig. 1 and confirm that a higher frequency leads to increased solubility of the cellulose. For instance, low solubility of approximately 30% was observed at 450 min − 1 after 20 min milling. An increase to 650 min − 1 led to considerably higher yields of 80% soluble material.

Structure and Source of Cellulose. Cellulose, a fascinating and sustainable feedstock, is the most abundant polymeric raw material on earth. Its annual production is estimated to be between 10 10 and 10 11 t, but only a small portion of 6 × 10 9 t is exploited by a number of industrial fields such as papers, textile, chemical, and material industries (Trache et al., 2020).
