Abstract
Highly reactive cellulose is prepared by mercerizing cellulosic material and reacting it with an hydroxyalkylating agent to a degree of substitution ranging from 0.05 to 0.3, said degree of substitution being short of rendering the cellulose appreciably soluble in water. The highly reactive cellulose is particularly useful for the preparation of such cellulose derivatives as cellulose acetate at considerably improved production levels.
