Popis:	Aminodeoxycelluloses were prepared by treating cellulose ρ-toluenesulfonates, which were prepared from various kinds of cellulose samples under various conditions, with a solution of ammonia in ethanol at 100° in an autoclave. From cellulose ρ-toluenesulfonates made at 0°, from never-dried, solvent-replaced regenerated cellulose, aminodeoxycellulose with a high degree of substitution (up to 0.82) was obtained with minimum side reaction. Acetylation and 2, 4-dinitro-phenylation of aminodeoxycellulose were studied. Some properties of aminodeoxycellulose are also reported.
