Oxidative conversion of glucose to gluconic acid by iron(III) chloride in water under mild conditions

 

 

A simple method was demonstrated to oxidize glucose into gluconic acid in a concentrated FeCl₃ solution. 

The maximum gluconic acid yield (52.3%) was achieved in the 40% FeCl₃solution at 110 °C in 4 hours. 

Formic and acetic acids were the main coproducts with an yield of 10–20%.
