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.
