| titleOfInvention | Method for producing methyl methacrylate |
| abstract | In the method for producing methyl methacrylate by subjecting methyl α-hydroxyisobutyrate to gas phase contact reaction, the reaction temperature is in the range of 230-300 ° C., and methanol is 0.1-to methyl α-hydroxyisobutyrate Method for producing methyl methacrylate, characterized in that it is supplied to the reactor at a rate of 3.0 times by weight, and a transition type synthesizer zeolite having a specific Na content (Na / Al) and a specific lattice constant is used as a catalyst. Presenting.n n n According to this method, it is possible to stably produce a desired product with high quality over a long period of time by preventing problems such as short-term deterioration of the catalyst and coloring of the reaction solution. |
