Laser ignitibility of insensitive secondary explosive 1,1-diamino-2,2-dinitroethene (FOX-7)

Initial decomposition mechanism for the energy release from electronically excited energetic materials: FOX-7 (1,1-diamino-2,2-dinitroethene, C2H4N4O4).

Decomposition of the energetic material FOX-7 (1,1-diamino-2,2-dinitroethylene, C2H4N4O4) is investigated both theoretically and experimentally. The NO molecule is observed as an initial decomposition product subsequent to electronic excitation. The observed NO product is rotationally cold (<35 K) and vibrationally hot (2800 K). The initial decomposition mechanism is explored at the complete ac...

1,1-Diamino-2,2-dintroethene (FOX-7) in copper and nickel diamine complexes and copper FOX-7.

1,1-Diamino-2,2-dinitroethene (FOX-7) reacts readily with copper nitrate in an aqueous solution of potassium hydroxide to form pea green Cu(FOX)(2)(H(2)O)(2) (5). FOX-7 complexes of copper and nickel supported by a variety of diamines including Cu(en)(2)(FOX)(2)(H(2)O) (1), Cu(pn)(2)(FOX)(2) (2), Cu(bipy)(FOX)(2)(H(2)O)(4) (3a), Cu(bipy)(2)(FOX)(2)(H(2)O)(2.5) (3b), Cu(bipy)(FOX)(2)(DMSO)(2)·2D...

A Candidate of New Insensitive High Explosive; MTNI

1-methyl-2,4,5-trinitroimidazole (MTNI; 1) was reinvestigated and fully characterized as a promising candidate of new insensitive high explosives. Compound 1 was synthesized from the imidazole (2), via 5 step reactions. According to our preliminary sensitivity tests, 1 was almost as insensitive as TNT. The explosive performances, i.e. detonation velocity, and C-J pressure, were evaluated theore...

Study of Nitro Factor Dislodgement in Fox-7

Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to predict the energies of atoms of FOX-7. Under gentle heating (thermolysis) is likely to cause hydrogen transfer between molecules, producing highly reactive chemical species. Conv...
