    摘要： The invention relates to a process for the preparation of secondary nitroxide radicals from their corresponding secondary amines by oxidation with an organic peracid, comprising the steps a) adding to a reaction vessel a secondary amine, optionally together with an organic solvent and in one batch a base selected from the group consisting of alkali metal, alkaline earth metal or ammonium bicarbonates and alkaline earth metal or ammonium carbonates or mixtures thereof in the form of a solid together with water or as an aqueous slurry; b) dosing a peracid under stirring to the reaction mixture in an amount of 1.0 to 2.5 mol per mol of secondary amine; and c) isolating the organic phase.

    摘要翻译： 本发明涉及通过用有机过酸氧化从其相应的仲胺制备二级氮氧自由基的方法，包括以下步骤：a）向反应容器中加入仲胺，任选与有机溶剂一起加入一次 碱选自碱金属，碱土金属或碳酸氢铵，碱土金属或铵的碳酸盐或其混合物，其形式为水，或与水相混合; b）在搅拌下将过酸给予反应混合物，其量为每摩尔仲胺为1.0至2.5摩尔; 和c）分离有机相。
