The oxidation of some α-hydroxy acids like glycolic, lactic and mandelic acids by tripropylammonium fluorochromate (TriPAFC) have been studied in aqueous acetic acid medium. The oxidation leads to the formation of the corresponding oxo acids. The reaction is first order with respect to TriPAFC, hydroxy acids and [H+] and the reaction is catalyzed by hydrogen ions. The reaction has been studied in different percentage of acetic acid-water mixture. A suitable mechanism has been proposed.
