Abstract
The invention relates to a process for the separation of a ketoxime or aldoxime from a ketoxime- or aldoxime-containing amide mixture in which the ketoxime or aldoxime is separated from the amide mixture by distillation. This has proved to be a very simple and direct method for separating the ketoxime and/or aldoxime from the desired amide.
