    摘要: A process for preparing n-amino-n-deoxy cellulose 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 triphenylmethyl chloride; then (b) reacting the product from (a) with acetic anhydride and dimethylsulfoxide. The product from (b) is then subjected to reductive amination. When n is 3 cellulose is reacted with dimethylsulfoxide and paraformaldehyde. The product from (a) is then reacted with acetic anhydride and dimethylsulfoxide and the product from (b) then subjected to reductive amination.
