Аннотация:It was found that the interaction of the modified paramagnetic defects =SiO(CH2)(n) C-. H-2 (n = 0.1) with nitromethane on a thermochemically activated silica surface at 300 K results in the formation of the following nitroxyl radicals: =SiO(CH2)(n)CH2ON(O-.)CH3 and =SiO(CH2)(n)CH2N(O-.)CH3. It was suggested that these radicals are the products of two different reactions of the modified paramagnetic defects: the first results from a reaction with free nitromethane; the second, from a reaction with nitromethane bound as complexes with diamagnetic surface defects.
