PLASTIC EXPLOSIVES BASED ON CIS-1, 3, 4, 6- TETRANITROOCTAHYDROIMIDAZO-[4, 5-D] IMIDAZOLE (BCHMX)

Initial Decomposition Reactions of Bicyclo-HMX [BCHMX or cis- 1,3,4,6-Tetranitrooctahydroimidazo-[4,5‐d]imidazole] from Quantum Molecular Dynamics Simulations

We investigated the initial chemical reactions of BCHMX [cis1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole] with the following procedure. First we used density functional theory molecular dynamics simulations (DFT-MD) on the periodic crystal to discover the initial reaction steps. This allowed us to determine the most important reactions through DFT-MD simulations at high temperatures. The...

4-(3-Fluoro-4-meth­oxy­phen­yl)-1-(4-meth­oxy­phen­yl)-5-(3,4,5-trimeth­oxy­phen­yl)-1H-imidazole

In the title mol-ecule, C(26)H(25)FN(2)O(5), the fluoro-meth-oxy-, meth-oxy- and trimeth-oxy-substituted benzene rings form dihedral angles of 12.65 (2), 84.15 (2) and 55.67 (2)°, respectively, with the imidazole ring. The crystal structure is stabilized weak inter-molecular C-H⋯F and C-H⋯O hydrogen bonds.

8 9 A comparison was made between the composition of the recalcitrant organic matter (ROM) 10 isolated from a sandy forest soil as revealed by microwave assisted extractions and/or 11 hydrolyses and by usual pyrolysis techniques. Successive microwave irradiation treatments 12 were performed in H2O, 0.1 and 1 M HCl and 0.1 and 1 M KOH. At each step of the 13 treatment the insoluble residue was e...
