Abstract
Den foreliggende oppfinnelsen angår fremgangsmåte til fremstilling av 4-substituerte 2,2,6,6-tetrametyl-piperidin-N-oksy-forbindelser [II] eller blandinger av [II] og 4- ' -substituert 2,2,6,6-tetrametyl-piperidin-N-hydroksy-forbindelser [III] hvor X+Y = O eller kan stå for et syklisk ketal med restene ¦: eller kan stå for et åpenkjedet ketal, hvor X = O-R og Y = O-R', hvor R og R' kan være like eller forskjellige og kan stå for CH3, CH2-CH3, CH2-CH2-CH3, CH(CH3)-CH3, CH2-CH2-CH2-CH3 og CH2-CH(CH3)-CH3, ved oksidasjon av tilsvarende 4-substituerte 2,2,6,6-tetrametylpiperidiner [I] med hjelp av hydrogen- peroksid i nærvær av alkali- og/eller ammonium-hydrogenkarbonat og eventuelt i nærvær av et løsningsmiddel, hvor reaksjonen gjennomføres under tilsetning av slike Brondstedtsyrer som har en syrestyrke større enn den til det anvendte hydrogenkarbonatet.
