HCID 10690Gluconic Acid

Procedure

By using 48.6 g of the thus-prepared catalyst (0.18% by weight based on glucose, calculated as palladium metal), an aqueous solution of glucose was reacted at a temperature of 30° ± 3° C and a pH of 10.0 in the same manner as described in Example 1 except that air was used instead of the oxygen gas employed in Example 1. Twenty one hours were required for completion of the reaction, and a liquid reaction mixture having a light brown color was obtained. The content of gluconic acid in the solid obtained by concentration of the liquid reaction mixture was 89.6 wt.% and the saccharide residual ratio was 5.3 wt.%.
