    Abstract: 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.

    Abstract: Novel energetic sulfate salts which form a eutectic with ammonium nitrate ntaining explosive formulations are disclosed. The eutectic quality of such formulations facilitates melt loading thereof. Two typical novel sulfate salts of the invention are 1-(2-ammonium sulfatoethyl)-2,4,6-trinitrobenzene and 1,3-Bis-2(2-ammonium sulfoethyl)-2,4,6-trinitrobenzene. Also disclosed is a method for the synthesis of such sulfate salts together also with a method for the synthesis of the necessary alkanol substituted trinitrobenzene derivative precursor.
