| titleOfInvention | Method for producing methyl methacrylate |
| abstract | PROBLEM TO BE SOLVED: To recover methanol by distillation from a reaction mixture containing at least methyl methacrylate and methanol obtained by direct esterification reaction of methacrolein and methanol, and to subject the recovered methanol to the direct esterification reaction In the method for producing methyl methacrylate used as a raw material, the hydrocarbons that need to be separated and recovered when methanol is recovered by distillation to simplify the process are not used as an azeotropic agent, and are contained in the recovered methanol. To reduce the amount of methyl methacrylate. SOLUTION: When recovering methanol by distillation, methacrolein is separately added as an azeotropic agent. |
