Abstract
PURPOSE: To obtain crystalline cellulose having high whiteness, causing no browning phenomena against unstable agent such as vitamin C, etc. in high yield without requiring pretreatment, by treating wet pulp with a mineral acid so that it is subjected to heterogeneous acid hydrolysis.
CONSTITUTION: Wet pulf sent from pulping process is hydrolyzed with 0.1W2.5N mineral acid preferably sulfuric acid at 90W160°C. The amount of the mineral acid is 3W50 times, preferably 8W20 times as much as that of solid content of pulp. After the reaction is over, the prepared residue unsoluble in the acid is purified and dried. The heterogeous acid hydrolysis is preferably carried out in a concentration of the mineral acid of 0.1W2.5 normal at treatment temperature of 90W160°C for treatment time of 10W180min at a bath ratio of 3W50.
