Abstract:
In an embodiment, a process for preparing an alkyl aryl carbonate and a diaryl carbonate, comprising: reacting a dialkyl carbonate and an aromatic hydroxy compound in a production column to form the alkyl aryl carbonate and the diaryl carbonate; directing a bottom stream of the production column to a reboiler, wherein the bottom stream comprises the alkyl aryl carbonate and the diaryl carbonate; heating the bottom stream in the reboiler with heat from an overhead stream of the production column to result in a heated bottom stream; directing a first portion of the heated bottom stream back into the production column, wherein the first portion comprises an aromatic hydroxy compound; and collecting the diaryl carbonate and the alkyl aryl carbonate from a second portion of the heated bottom stream.
