Abstract

Ammonium perchlorate (AP) is most often used as the practical solid rocket propellant because of its excellent performance. However, AP has many shortcomings including instability, high negative enthalpy of formation, and claimed health and environmental issues resulting from its combustion products. The pursuit of highly dense, high performance and environmentally friendly oxidizers as solid propellants has long attracted scientists around the world. In this work, bis(3-nitro-1-(trinitromethyl)-1H-1,2,4-triazol-5-yl)methanone (3) was obtained from bis(3-nitro-1H-1,2,4-triazol-5-yl)methane (1) with chloroacetone followed by nitration. The structure of 3 was confirmed by elemental analysis and X-ray single crystal diffraction. By introducing the carbonyl moiety, the density of 3 was increased to 1.945 g/cm3 and the decomposition temperature increased to 164 oC. Compound 3 is a green energetic oxidizer that has a positive oxygen balance (+8.7 %), high specific impulse (218 s) and an acceptable sensitivity (9J, 240N) making it a practi-cal replacement for AP in solid rocket.
