Patent ID: 7531690

Claim:
A process for producing an oxygen-containing compound, comprising reacting an olefin and oxygen in a gas phase in the presence of a catalyst, wherein the olefin is propylene, the oxygen-containing compound is at least one compound selected from acetone, propionaldehyde, propionic acid and acetic acid; and the catalyst is represented by the following formula: Pd/W a ZrO x wherein Pd is a palladium-containing compound, a is a W/Zr molar ratio of from 0.01 to 5.0, and x is a value defined by the oxidized state of tungsten (W), zirconium (Zr) and palladium (Pd), and wherein the content of palladium element in the catalyst is from 0.001 to 15 parts by mass based on 100 parts by mass of W a ZrO x .
