The outstanding property of the SnO<SUB>2</SUB>–MoO<SUB>3</SUB> catalyst in the oxidation of propylene to acetone was confirmed by tests of various oxide catalysts supported on pumice. The optimum composition was found to be SnO<SUB>2</SUB>-70/MoO<SUB>3</SUB>-30 mol % for the oxidation at from 170 to 260 °C. It was also found that this pumice-supported catalyst is sufficiently selective for the acetone formation even at a high temperature of 260 °C, and that it gives a high yield of acetone while keeping its high selectivity. The selectivity increases up to 90 mol % with an increase in the partial pressure of water vapor and with a decrease in the oxygen partial pressure. On the basis of such information, it can be said that a high yield of acetone can be obtained by the divided introduction of oxygen.
