Process for the preparation of methyl methacrylate |
| abstract |
A process for producing methyl methacrylate, which comprises subjecting methacrolein and methanol to direct esterification reaction to thereby obtain a reaction mixture liquid containing at least methyl methacrylate and methanol, adding additional methacrolein to the reaction mixture liquid as an entrainer, and distilling the resulting reaction mixture liquid to recover the methanol. |
