Method and apparatus for the production of diaryl carbonate |
| abstract |
In an embodiment, a method for production of diaryl carbonate by reaction of a dialkyl carbonate and an aromatic alcohol in the presence of a transesterification catalyst, comprising: producing a first top stream (5) comprising dialkyl carbonate and alkyl alcohol from a first reactive distillation column (210); introducing a reactant stream (5') comprising the first top stream (5) to a first divided wall distillation column (DWC1 200) and separating the mixture with use of the first divided wall distillation column (DWC1 200); recovering from the first reactive distillation column (210) a first bottom stream (6) comprising alkyl aryl carbonate; and introducing the first bottom stream (6) into a second reactive distillation column (320) to produce a second bottom stream (15) comprising diaryl carbonate. |
