Synthesis of Energetic Materials.
Abstract
Investigation of the synthesis of polyformals from severl nitro- and fluorodiols was continued. A new fluoropolyformal derived from 2,4,4,5,5,6,6-heptafluoro-2-trifluoromethyl-3-oxaheptane-1,7-diol was obtained. Formation of the homopolyformal of 4,4-dinitroheptane-1,7-diol was studied to assess effects of changing reaction parameters on molecular weight. Copolyformal formation was studied for several monomer (diol) pairs, especially DINOL/4,4-dinitroheptane-1,7-diol, and was demonstrated by GPC and 'H NMR analysis of the polymer products. Effects of varying reaction parameters and monomer ratios were investigated qualitatively. The synthesis of the trifluoromethyl stabilized ring system of bicyclo-HMX (2,4,5,8-tetraza-bicyclooctane) was investigated and the di-, tri-, and tetranitro derivatives were prepared and characterized. The chemistry of the 2,6-diazabicyclooctane ring system was studied toward the synthesis of tetra- and hexa-substituted nitro derivatives. Several dinitro derivatives were prepared. A new reduction of nitroamides to nitramino alcohols was discovered. (Author)
