Oxygen → Gluconic Acid

Participants

Reaction Steps

By using 27.0 g of the thus prepared catalyst (0.1% by weight based on glucose, calculated as palladium metal), an aqueous solution of glucose was oxidized 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 used in Example 1. The reaction was completed in 2.5 hours and a colorless transparent liquid was obtained. The content of gluconic acid in the solid obtained by concentration of the liquid was 98.0 wt.% and the saccharide residual ratio was 1.2 wt.%.
