Abstract:

Sodium tungstate/hydroperoxide was used for the preparation of glucuronic acid and its lactone by selective oxidation of primary hydroxyl group of methyl glucoside. The effects of different catalytic oxidative conditions on the yield were studied. The products were determined by HPLC. A reaction mechanism was proposed. The catalytic system exhibits high activity and good selectivity on the oxidation of primary hydroxyl of methyl glycoside. Combined yield of glucuronic acid and its lactone is up to 74.07%. Compared with the traditional HNO3 oxidation of starch, this process is more environmental-friendly and economical.

Key words: sodium tungstate/hydroperoxide system, methyl glucoside, glucuronic acid, selective oxidation
