Abstract
A process of treating a ketoxime or aldoxime-containing amide mixture resulting from a Beckmann rearrangement of the corresponding ketoxime or aldoxime. The process involves hydrolysis of the mixture to remove the remaining ketoxime or aldoxime which are converted to the corresponding ketone or aldehyde and then separated off from the mixture. Any amino acid resulting from the hydrolysis can be reconverted to the corresponding amide by raising the temperature of the mixture.
