- Аннотация: Adducts of hydroxides of Li, Na, K, Mg, Ca, Sr, Cr, Fe, Ni, Co, Cu, Cd, Ba, Pb, ammonia, and hydrazine with 4, 6-dinitrobenzofuroxan (DNBF) have been synthesized and studied. IR-spectroscopy analysis data suggested all the salts to be divided into two groups depending on the chemical nature of metal cations. The first group includes adducts which have the Meisenheimer complex (alpha-complex) structure with metal atom located to oxygen atoms of nitro-group in the aci-form. The second one comprises adducts in which metal atom is covalently bound to the oxygen atom of hydroxyl group. Burn rate characteristics of a-complexes of both the types have been first studied in this work in the pressure interval of 0.1similar to30MPa. The experimental data unambiguously testify that the maximum catalytic (accelerating) effect at entering metal atom into the explosive molecule with N-O bonds can be achieved only when the metal is located to oxygen atoms of nitro-group in the aci-form. For most part this effect turned out to be irrespective of the chemical nature of metal introduced. However, the potassium salt of DNBF has showed the highest burning rates among others and, consequently, may be expected to have maximum initiating properties.
