1-(2-Nitroxyethylnitramino)-2,4,6-trinitrobenzene (I-A), 1,3-bis(2-nitroxyethylnitramino)-1,4,6-trinitrobenzene (II-A) and 1,3,5-tris(2-nitroxyethylnitramino)-2,4 (III-A) have been prepared by condensing picryl chloride, styphnyl chloride and 1,3,5-trichloro-2,4,6-trinitrobenzene with ethanol amine, respectively, followed by nitration. These compounds have been characterized by infrared spectrum (IR), the elemental analysis and H-1 NMR. Further, these compounds have been studied for their thermal and explosive properties. The activation energy of thermal decomposition of these compounds has also been determined using the Ozawa and the Kissinger methods. The data on explosive properties indicate that the impact, friction and velocity of detonation (VOD) increase with an increase in the number of nitrate ester groups.
