摘要：

The direct oxidation of benzene, beta-picoline and propylene, respectively, were carried out by 'one-pot' reactions. A steamed H-[Al]-ZSM-5 with strong Lewis acid sites yields the best results in the oxidation of benzene with N2O. P-picoline can be directly oxidized with O-2 in the gas-phase to nicotinic acid in the presence of a V2O5 impregnated TiO2 catalyst having Bronsted acid sites in addition to redox properties. Yields up to 98% can:be achieved. The propylene oxide synthesis is based on the oxidation of propylene by using a O-2-H-2 gas mixture over Pd/Pt-impregnated TS-1. Selectivities up to 85% are obtained at conversions between 15 and 20%. (C) 2000 Elsevier Science B.V. All rights reserved.
