The invention relates to a process for the purification of epoxides or mixtures containing epoxides, which contains up to 2% by weight of a carbonyl compound containing 1 to 5 carbon atoms, by introducing the epoxide into the central region of a distillation unit above the feed of the epoxy-containing one Product stream introduces a compound which has one or more unsubstituted NH 2 groups and withdraws the purified epoxide as a top product or as a side stream above the point of introduction of this compound containing at least one NHz group into the distillation column. |
