Combination of Best Promoter and Micellar Catalyst for Chromic Acid Oxidation of D-Arabinose in Aqueous Media at Room Temperature.

The present paper describes the kinetics and mechanism for oxidation of D-arabinose by Cr(VI) in the presence of a micellar media. The anionic surfactant sodium dodecyl sulphate (SDS) and nonionic surfactant Triton-X-100 (TX-100) accelerate the process w h ile the cationic surfactant A/-cetylpyridinium chloride (CPC) retards the reaction. A suitable mechanism has been proposed. The reaction constants involved in different steps of the mechanism have been calculated. Formic acid and erythronic acid were reported as the products of oxidation of the sugar. [ABSTRACT FROM AUTHOR]
