Development of new halogen free green energetic oxidizers 1,1′‐methylenebis[3‐(2,2,2‐trinitroethyl)urea] and 1,1′‐methylenebis[1‐nitro‐3‐(2,2,2‐trinitroethyl)urea] results from sensitive H‐FOX in good yields. Both compounds have high nitrogen and oxygen content and exhibit high densities and good detonation properties.
The Unimolecular Chemistry of Protonated and Deprotonated 2,2-Dinitroethene-1,1-Diamine (FOX-7) Studied by Tandem Mass Spectrometry and Computational Chemistry
electrospray ionization (ESI) and chemical ionization (CI) massspectrometry in both positive and negative ion mode. Detailed mechanisms of unimolecular fragmentations of protonated and deprotonated FOX-7 were investigated using high- and low-energy collision-induced dissociation (CID) massspectrometry, neutral fragment reionizationmassspectrometry and quantum chemistry calculations. In deprotonated FOX-7

The impact sensitivity (IS) of FOX-7 polymorphs is predicted by phonon up-pumping to decrease as layers of FOX-7 molecules flatten. Experimental validation proved anomalous owing to a phase transition during testing, raising questions regarding impact sensitivity measurement and highlighting the need for models to predict IS of polymorphic energetic materials.
