Abstract

Framgangsmåte for alkalisk oksidativ degradering av en ose, ulese samt polymerer eller blandinger av samme, i en vandig løsning i nærvær av et redokspar omfattende en blanding av 2-anU-aquinon-monosulfonsyre og hydrogenperoksid. Den oksiderende gass er luft som røres opp og tilføres reaksjonsmediel under omrøring og ved en strømningsrale slik at oksygenmetning av reaksjonsmediel fører til dannelse av en lyserød farge i reaksjonsmediel.
