ABSTRACT:
Method of producing microcrystalline cellulose. Cellulose containing at least about 92% alpha-cellulose and 5 - 6.5% beta cellulose, having a solubility in 5% sodium hydroxide of about 2 to 4% and a viscosity 110 to 180 mP is acid hydrolyzed and the resulting crystalline mass is de-aggregated, the acid hydrolysis being performed at the same time as the chemical de-aggregating of the material. The de-aggregated material may be bleached and cleaned if desired.
