The invention relates for a method for recovering stable nitroxide radicals, wherein at least a part of a reaction mixt. consisting of a soln. or suspension, or a filtrate or supernatant of a suspension, in which stable nitroxide radicals are present in non-solid form, is subjected to an azeotropic distn. The invention further relates to a method for the selective oxidn. of compds. which contain at least one hydroxyl group, using stable nitroxide radicals as catalyst, wherein the liq. phase of the mixt. contg. the reaction products is subjected to an azeotropic distn., where after the nitroxide radical-contg. distillate is recirculated to the reaction vessel.
