Abstract
In a new process for oxidizing a primary and/or secondary alcohol, an oxidizing agent is used in the presence of a di-tertiary-alkyl nitroxyl, in an aqueous reaction medium at a pH of below 7. The di-tertiary-alkyl nitroxyl is especially 4-hydroxy-TEMPO, and the process is particularly advantageous for oxidizing carbohydrates such as starch.
Claims17
A process for oxidising a carbohydrate or a reduced, hydroxyalkylated or carboxyalkylated carbohydrate derivative comprising oxidising the carbohydrate or a reduced, hydroxyalkylated or carboxyalkylated carbohydrate derivative in an aqueous reaction medium at a pH below 7 using an oxidising agent consisting essentially of a hypohalite, hydrogen peroxide or ozone in the presence of a di-tertiary-alkyl nitroxyl.
