A new high energetic bonder intermediate azidodeoxycellulose for solid propellant was synthesized from the raw material cotton linters under homogeneous conditions. The process of preparing azidodeoxycellulose includes two steps. The first is the tosylation of cellulose with tosylchloride using triethylamine as catalyst and the dimethylacetamide/LiCl system as solvent to obtain cellulose tosylate with certain ester number. The second is nucleophilic substitution reaction of the cellulose tosylate with NaN_3...
