ABSTRACT OF THE DISCLOSURE A process for preparing n-amino-n-deoxy cellu- lose where n is 2 or 3 and has the same value at each occurrence in one molecule. When n is 2 cellulose is selectively oxidized by (a) reacting it with triphe- nylmethyl chloride; then (b) reacting the product from (a) with acetic anhydride and dimethyl sulfoxide. The product from (b) is then subjected to reductive amina- tion. When n is 3 cellulose is reacted with dimethyl sulfoxide and paraformaldehyde. The product from (a) is then reacted with acetic anhydride and dimethyl sulfoxide and the product from (b) then subjected to reductive amination. -25-
