Process for producing methacrolein and methacrylic acid |
| abstract |
The present invention is directed to catalytic oxidation of methacrolein from isobutylene by using a catalyst containing a compound oxide containing molybdenum, bismuth and iron as a temperature of (T-3) ° C. or less [where T is an essential component. And the boundary temperature of the activation energy of the reaction producing methacrylic acid, and the reaction is continued while the reaction temperature increases as the catalytic activity decreases, before the reaction temperature exceeds the boundary temperature of the activation energy. Methacrolein and methacrylic acid by catalytic oxidation of isobutylene or tertiary butanol over a catalyst containing a compound oxide containing molybdenum, bismuth and iron as essential components, including activating the catalyst at least once It relates to a method of manufacturing. |
