A method for producing methyl methacrylate including:a distillation step including:supplying a reaction solution, which is obtained by subjecting methacrolein, methanol, and molecular oxygen to oxidative esterification in an oxidative esterification reactor and which contains the methyl methacrylate as a reaction product, to a first distillation column located at downstream of the oxidative esterification reactor,extracting a fraction containing the methacrolein and the methanol from a medium section of the first distillation column, andextracting a column bottom liquid containing the methyl methacrylate from a column bottom of the first distillation column,wherein a concentration of the methanol in the column bottom liquid is 1% by mass or more and 30% by mass or less. |
