Abstract
Base-free oxidation of glucose to gluconic acid with
supported gold catalysts was studied using microwave
heating. High conversion and selectivity were obtained in
a remarkably shortened reaction time; in 10 min gluconic
acid was obtained with up to 76% yields with 0.09 mol%
Au/Al2O3 and hydrogen peroxide as oxidant. Very high
turn-over frequencies over 10,000 h- 1 were measured for
the microwave assisted oxidation. Moreover, the catalyst
activity remained constant in four consecutive runs, even
though minor particle growth was observed.
