acid hydrolysis of cellulose in zinc chloride solution

How does cellulose hydrolysis work?
The cellulose hydrolysis protocol itself first involved the preparation of an acid solution by mixing some 95–98 wt% sulfuric acid with water, to get the required mass ratio of sulfuric acid/dry cellulose ( R1) and mass percentage of sulfuric acid ( C1) (when accounting for cellulose humidity) and cooled to 5–10°C in an ice-cold water bath.
Can hydrochloric acid hydrolysis catalyze cellulose nanocrystals?
Efficient extraction of cellulose nanocrystals through hydrochloric acid hydrolysis catalyzed by inorganic chlorides under hydrothermal conditions ACS Sustain. Chem. Eng., 5 ( 2017), pp. 4656 - 4664
Which acid is optimum for cellulose hydrolysis?
Xiang et al. (2003) also found a mass percentage of 72 wt% sulfuric acid to be the optimum for cellulose hydrolysis, although the mass ratio of acid/dry cellulose ratio used in their case was only 19.6 and the highest mass percentage of acid investigated was 72 wt%.
Does low phosphoric acid concentration cause partial hydrolysis of cellulose?
Phosphoric acid concentration plays a significant role in hydrolysis rate, and it has been stated that low phosphoric acid concentration (7.8 M) causes partial hydrolysis of cellulose, no matter how much time may be employed for hydrolysis.
