RDX was widely used during World War II, often in explosive mixtures with TNT such as Torpex, Composition B, Cyclotols, and H6. RDX was used in one of the first plastic explosives. The bouncing bomb depth charges used in the "Dambusters Raid" each contained 6,600 pounds (3,000 kg) of Torpex; The Tallboy and Grand Slam bombs designed by Wallis also used Torpex. Webin the RDX decomposition is a concerted symmetric triple fission of RDX ring. Based on the reported heat of formation of 33.6 kcal/mol for methylenenitramine (MN) by Melius and Binkley,21 ZHL estimated the endothermicity to be 80 kcal/ mol for the concerted ring fission (which compares with the N-N bond dissociation energy of 48 kcal/mol ...
