Abstract

Process for distillatively separating a mixture containing a vinyl ether of the general formula (I)R1—O—CH═CH2 (I)and alcohol of the general formula (II)R2—OH (II)in which R1 and R2 are each independently a saturated or unsaturated, aliphatic or cycloaliphatic radical having from 2 to 10 carbon atoms, and in which the alcohol (II) has a boiling point which is at least 1° C. higher, measured at or extrapolated to 0.1 MPa abs, than the vinyl ether (I), by
