In one embodiment, the presence of a transesterification catalyst A method for producing a diaryl carbonate by reacting dialkyl carbonate and an aromatic alcohol, the agent comprising the dialkyl carbonate and alkyl alcohol from the first reaction distillation column 210 1 generating a top stream 5; Using the first top stream 5 the reactant stream (5 ') of the first dividing wall distillation column, introducing the DWC1 (200), the first dividing wall distillation column DWC1 (200) including a separating said mixture the method comprising; Recovering a first bottom stream (6) containing the alkyl aryl carbonate from the first reactive distillation column 210; And generating a second bottom stream 15 containing the diaryl carbonate by introducing the first bottom stream (6) into the second reaction distillation column 320.
