Producing alkylaryl carbonates and/or diaryl carbonates from dialkyl carbonates and aromatic hydroxy compounds in the presence of a catalyst in a distillation column, which completely or partially prevents cross-mixing of liquid- and/or vapor stream using a separation device that is subdivided into a feed line and a discharge line, comprises supplying an aromatic hydroxy compound containing stream (21) and dialkyl carbonate-containing stream (22) to the feed line and separating one or more middle boiling fractions containing reactants and/or reaction byproducts, in a vapor or liquid form. Producing alkylaryl carbonates and/or diaryl carbonates from dialkyl carbonates and aromatic hydroxy compounds in the presence of a catalyst in a reactive distillation column, which completely or partially prevents cross-mixing of liquid- and/or vapor stream using a longitudinally effective separation device that is subdivided into a feed line located in a reaction zone, and a discharge line, comprises supplying an aromatic hydroxy compound containing stream (21) and dialkyl carbonate-containing stream (22) to the feed line and separating one or more middle boiling fractions containing reactants and/or reaction byproducts, in the form of vapor or liquid. |
