Process for producing methacrylic acid |
| abstract |
It is an object of the present invention to provide a method for producing methacrylic acid with good productivity over a long period of time. The present invention relates to a process for producing methacrylic acid by supplying methacrolein, isobutylene and oxygen to a reactor for producing methacrylic acid provided with a catalyst layer containing a catalyst for methacrylic acid production, Wherein the maximum temperature in the catalyst bed is at most 330 < RTI ID = 0.0 > C. ≪ / RTI > The maximum temperature in the catalyst layer is preferably set to 330 DEG C or less by adjusting the feed amount of isobutylene. |
