Raw material for catalyst production, method for producing the same, method for producing the catalyst, and method for producing methacrylic acid |
| abstract |
Molybdenum recovered from a catalyst containing at least molybdenum and element A (A is at least one selected from the group consisting of phosphorus and arsenic) used in the reaction, a compound containing element A, and molybdenum such as molybdenum trioxide An object of the present invention is to provide a raw material for producing a catalyst that can be applied to the production of a catalyst using an oxide as a raw material and can effectively use resources, a production method thereof, a catalyst using the same, and a production method of methacrylic acid. A precipitate obtained by adjusting the pH of a mixed solution containing at least molybdenum and element A (A is at least one selected from the group consisting of phosphorus and arsenic) is obtained by heat treatment at 250 to 350 ° C. Raw material for producing a catalyst, which has a diffraction peak attributed to a heteropolyacid or heteropolyacid salt having a Keggin structure by X-ray diffraction measurement and does not have a diffraction peak attributed to molybdenum oxide . [Selection figure] None |
