| titleOfInvention | Method for producing methacrylate ester |
| abstract | Using a reactor equipped with a distillation column, the transesterification reaction between methyl methacrylate and alcohol or phenols was carried out while removing methanol produced as a by-product under reflux conditions as an azeotrope with methyl methacrylate. In the method for producing a methacrylic acid ester, when the temperature in the distillation column is converted to a temperature at normal pressure, the uppermost temperature is 63 to 68 ° C, the intermediate temperature is 68 to 90 ° C, and the lowermost temperature is After the temperature reaches 90 to 100 ° C., the azeotropic mixture of methanol and methyl methacrylate is started to be removed from the system, and when the conversion rate of alcohol or phenol is in the range of 0 to 95%, the distillation column By controlling the reflux ratio so as to maintain the internal temperature, the methacrylic acid ester is produced with high productivity. |
