摘要：

Gas phase selective oxidation of propylene re, propylene oxide (PO) or propionaldehyde (PA) in the presence of H-2 and O-2 has been carried out with a propylene conversion in the range of 0.5-3.7% over gold deposited on titanosilicates by deposition-precipitation (DP) method; PO was obtained with a selectivity above 90% at the: temperature range of 50 degrees C-120 degrees C whereas PA was obtained at temperatures higher than 200 degrees C with a selectivity above 70% over thoroughly washed catalysts with low Au loadings.
