Micellar effects on the reaction of Cr(VI) oxidation of hexitols in the presence and absence of picolinic acid in aqueous acid media

Abstract

In aqueous acidic media, picolinic acid (PA) promoted Cr VI-oxidation of the hexitols to the respective aldohexoses goes on, along with a slower uncatalysed path; the anionic surfactant (SDS) accelerates the process while the cationic surfactant (CPC) retards the reaction.
