Beschreibung
Zusammenfassung:	Purifying dialkyl carbonate in at least one distillation column comprising at least a reinforcing element at the top of the column and at least a stripping section at the bottom of the column, comprises processing dialkyl carbonate-alkyl alcohol mixture, which is obtained at the head of a transesterification column, in the distillation column using a technical device for heating the column internal liquid flow, where the energy for heating the column internal liquid flow is obtained partially or completely from another chemical process.
