Synthesis, Characterization, and Energetic Studies of Polynitro Aryl-1,2,3-2H-Triazoles

Abstract

A series of energetic polynitro-aryl-1,2,3-2H-triazoles are synthesized from readily accessible aryl-1,2,3-2H-triazoles. X-ray diffraction analysis established the solid-state structures of several representative molecules. The thermal properties are determined by differential scanning calorimetry and thermogravimetric analysis (DSC-TGA) data. Based on computational studies, most of the compounds showed positive heats of formation and the densities were 1.55 to 1.83gcm-3. In addition, the compounds were thermally stable (Td > 210°C) and exhibited acceptable detonation properties.
