Abstract: The invention relates to a method for the distillative separation of a mixture containing a vinyl ether of general formula (I) R1-O-CH=CH2 and an alcohol of general formula (II) R2-OH, in which R1 and R2 independently of one another represent a saturated or unsaturated, aliphatic or cycloaliphatic group with between 2 and 10 carbon atoms and the alcohol (II) has a boiling point that is at least 1 °C higher than that of the vinyl ether (II), when measured at or extrapolated to 0.1 MPa abs. According to said method a) the mixture is fed into a first distillation column and an azeotrope containing a vinyl ether (I) and an alcohol (II) is extracted as the head product and a stream containing a concentration of alcohol (II) is extracted as the sump product; b) the azeotrope containing the vinyl ether (I) and the alcohol (II) is then fed from the first distillation column into a second distillation column, which is operated at a pressure that is 0.01 to 3 MPa higher than that of the first distillation column, where the vinyl ether (I) is extracted as the sump product or as a gaseous lateral discharge in the stripping section and an azeotrope containing a vinyl ether (I) and alcohol (II) is extracted as the head product; and c) the azeotrope containing the vinyl ether (I) and alcohol (II) is fed back from the second distillation column into the first distillation column.
