Process for making azidodeoxycellulose

【摘要】This invention is an improved process of making azidodeoxycellulose a hig energetic ingredient for use in a propellant. The process is accomplished by nitrating cellulose to nitrocellulose, converting the nitrocellulose in sequence to the iodine derivative, and finally reacting the iodine derivative of cellulose with sodium azide to produce azidodeoxycellulose having up to about 1.5% residual nitrogen as nitrate groups.

I claim: 1. A process for making azidodeoxycellulose comprising nitrating cellulose to nitrocellulose, converting said nitrocellulose to the iodine derivative, and reacting said iodine derivative with sodium azide to produce azidodeoxycellulose having up to about 1.5% nitrogen in the form of residual nitrate groups. 2. The process of claim 1 wherein between about 0.5 and 1.5 g of said iodine derivative of nitrocellulose is present in proportion to about 1 g of sodium azide. 3. The process of claim 1 wherein between about 0.5 and 1.5 g of the iodine derivative of nitrocellulose, about 1 g of sodium azide, and about 35 ml of dimethylformamide are heated, with stirring, for about 7 hours at a temperature between about 75.degree. and about 80.degree. C. 4. The process of claim 3 wherein about 0.5 g of the iodine derivative of nitrocellulose is present. 5. The process of claim 3 wherein about 1.5 g of the iodine derivative of nitrocellulose is present. GOVERNMENTAL INTEREST The invention described herein may be manufactured, used and licensed by or for the Government for Governmental purposes without payment to me of any royalties thereon. FIELD OF INVENTION This invention relates to an improved process of making azidodeoxycellulose. In the art, azidodeoxycellulose is made by initially mercerizing cellulose with sodium hydroxide, filtering, and washing with methanol. In sequence, the mercerized cellulose is then converted to the tosylate derivative. This procedure is set fort
