| titleOfInvention | Process for preparing stabilized nitroxide free radical compound |
| abstract | The present invention relates to a method for preparing stabilized nitroxide free radicals through oxidation of 2,2,6,6-tetraalkylpiperidine compounds, and more particularly, a) 2,2,6,6 Reacting the tetraalkylpiperidine compound with hydrogen peroxide in an aqueous solution saturated with an unreactive salt in the presence of a catalyst and a basic chelating agent to synthesize an aqueous solution of nitroxide free radicals; b) after the completion of step a), adding an organic solvent to the solution to extract nitroxide free radicals; c) washing the organic solution layer with washing water; It provides a method for producing a high purity nitroxide free radical.n n n Nitroxide free radicals, 2,2,6,6-tetramethylpiperidine |
