FIELD: chemistry.
SUBSTANCE: invention relates to a method of purifying dialkyl carbonates in at least one distillation column which is provided with at least one fortifying section in the upper part of the column and at least one exhausting section in the lower part of the column, wherein the distillation column for processing a mixture containing dialkyl carbonate and alkyl alcohol, said mixture being collected from the upper part of a reesterification column, employs a means of heating the inner liquid stream, wherein the inner liquid stream is partially or completely heated using energy obtained from another chemical synthesis process.
EFFECT: unlike existing methods, the present method is characterised by lower power consumption.
