Beschreibung
Zusammenfassung:	Processes for refining dialkyl carbonate-containing compositions are described, wherein a composition comprising a dialkyl carbonate is provided; and the composition is subjected to a rectification wherein low-boiling impurities are removed, and a rectification wherein high-boiling impurities are removed; and subsequently to a deodorization wherein medium-boiling impurities are removed.
