Abstract
It was found that the interaction of the modified paramagnetic defects ≡SiO(CH2) n \({\text{C}}^ \cdot\)H2 (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(\({\text{O}}^ \cdot\))CH3 and ≡SiO(CH2) n CH2N(\({\text{O}}^ \cdot\))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.
