A method for producing a diaryl carbonate comprising the steps of: introducing a reactant into the first reactive distillation column (C21); A first step of recovering the upper stream (stream 5), the first bottoms stream (stream 6), and a first side stream (stream 13); Without passing through the other reactive distillation column comprising: introducing the first bottoms stream (stream 6) to the second reaction distillation column (C32); Recovering a second bottoms stream (stream 15), and second top stream (stream 16) from the second reactive distillation column (C32); Introducing the first side stream (stream 13) to the first rectification column (C81); Recovering the third bottoms stream (stream 12), and a third top stream (stream 14) from the first rectifying column (C81); Introducing the first top stream (stream 5) to the second rectifying column (C41); And it may include the step of recovering the fourth top stream (stream 7), and a fourth bottom stream (stream 8) from the second rectification column (C41).
