摘要： Dimethyl ether is converted to formaldehyde using a supported catalyst comprising molybdenum and/or vanadium oxides. The surface density of the oxide(s) ranges from greater than that for the isolated monomeric oxides upwards, so long as there is a substantial absence of bulk crystalline molybdenum and/or vanadium oxide(s). Conversion and selectivity to formaldehyde are improved as compared to data reported for known catalysts. Also disclosed is a catalyst comprising molybdenum and/or vanadium oxides supported on a layer of stannic oxide that is disposed on the surface of a particulate alumina or zirconia support.

The production process for the catalyst comprises the steps of: carrying out heat treatment of an aqueous solution or slurry of a starting material to thus prepare a catalyst precursor P1, wherein the starting material includes molybdenum, bismuth, and iron as essential components; thereafter adding and mixing a binder into the P1 to thus prepare a catalyst precursor P2; and molding and then calcining the P2, thereby producing the catalyst for synthesis of the unsaturated aldehyde and/or the unsaturated carboxylic acid; with the production process being characterized by involving an ignition loss ratio of the catalyst precursor P1 in the range of 10 to 40 mass % (excluding 40 mass %).
