| titleOfInvention | Method for purifying methyl methacrylate |
| abstract | (a) feeding a mixture comprising methyl methacrylate and its alkali metal salt into a distillation column above the middle with hydrocarbons; (b) removing the first overhead stream; c) removing the first bottoms stream; (d) feeding a first overhead stream to a first water separator to form a first aqueous phase entering the methanol dry distillation column producing (i) a first organic phase and (ii) a second overhead stream and a second bottom stream; ≪ / RTI > (e) feeding a first bottoms stream to a second water separator to provide (i) a second aqueous phase fed to an MMA stripper distillation column producing a third overhead stream and a third bottoms stream, and (ii) ≪ / RTI > (f) integrating the second organic phase and the second bottoms stream into a third water separator producing a third organic phase entering the MMA dry distillation column producing a fourth overhead stream; And (g) feeding the fourth bottoms stream to an MMA product distillation column to purify methyl methacrylate. |
