The oxidation of ethanol to acetate ion by gaseous oxygen in an aqueous sodium carbonate solution with 0.5Vertical Bar3< palladium-on-alumina as catalyst was carried out in a jacketed, 1 gal stirred autoclave at 33-37 mm Hg above atmospheric and at 25/sup 0/, 35/sup 0/, and 45/sup 0/C to determine reaction kinetics. The rate was essentially first order in oxygen, increased with ethanol concentration in the range 0.45-1.80 g-mole/l., and exhibited a maximum with respect to sodium carbonate concentration at 0.1 g-mole/l. The tortuosity factor for the alumina catalyst support was 2.9. The reaction will serve as a model for studying fast gas-liquid-solid reactions.
