Abstract

Bei einem Verfahren zur Reinigung von Carbonsäureestern, wie Ethylformiat, destilliert man einen zu reinigenden Carbonsäureester in Gegenwart eines Extraktionsmittels, vorzugsweise indem man (a) Brüden des zu reinigenden Carbonsäureester in einer Destillationskolonne aufsteigen lässt; (b) dem Brüden in einer Extraktivdestillationszone das Extraktionsmittel entgegenführt; (c) oberhalb der Extraktivdestillationszone reinen Carbonsäureester abzieht. Das Extraktionsmittel ist z.B. unter Diolen, Polyolen, offenkettigen oder cyclischen Amiden ausgewählt.
