The inside cover picture shows the molecular structure of bis(2,2,2‐trinitroethyl)oxalate (BTNEOx) as determined by single crystal X‐ray diffraction (center right). BTNEOx is a new chlorine‐free high energy dense oxidizer (HEDO). The new HEDO was formulated with nitrocellulose (NC) to yield a homogeneous double‐base propellant formulation with high thermal stability as indicated by thermo gravimetric analyses (center left). BTNEOx itself has a melting temperature of 104 °C and a decomposition temperature of 200 °C. The activation energy for the decomposition is in the range of 107–110 kJ mol −1 . The prepared NC‐BTNEOx formulation has no endothermic peak and shows exothermic decomposition at 202 °C. The prepared NC‐BTNEOx has activation energy in the range of 172–180 kJ/mol. The new double base formulation combusts completely smokelessly and could be of high interest for application in large caliber guns as well as for air‐borne (top) or surface‐launched (bottom) missiles.
