Process for preparing a catalyst for use in production of methacrylic acid and process of preparing methacrylic acid |
| abstract |
The present invention provides a process for preparing a catalyst and the same for use in production of methacrylic acid, which is characterized by molding a raw material including a powder containing phosphorus and molybdenum at the specific pressure. The invention also provides a process for preparing methacrylic acid by gas phase oxidation and/or oxidative dehydrogenation of at least one compound selected from the group consisting of methacrolein, isobutyraldehyde and isobutyric acid in the presence of the catalyst. |
