A New Method for the Nitration of Nitrocellulose Azide Derivative

Binders and plasticizers containing energetic groups such as nitro (-NO2), fluorodinitro (FC(NO2)2-), difluoroamino (-NF2), azide (-N3) and nitrate (-ONO2) have been developed and used in formulation of energetic materials. In this research paper, the synthesis of a high N-component energetic material possessing both energetic functional groups ONO2 and N3 in its molecular structure has been investigated. This compound is Azidodeoxycellulose nitrate(II). To reach the target molecule, nitration of azidodeoxycellulose(I) was performed using acetic anhydride, 98% HNO3 at 0◦C in CH2Cl2 Solvent. The presence of azido groups and the enhancement of nitrogen percent were confirmed by IR spectroscopy and elemental analysis. The heat of explosion and the volume of the obtained gas were investigated by calorimetric and gasometric methods respectively.
