Abstract: Treatment of a ketoxime- (pref. cyclohexanone oxime) or aldoxime-contg. amide mixt. obtd. by a catalytic Beckmann rearrangement of the corresponding oxime, by hydrolysing the oxime-contg. mixt., sepg. off the prods. from the corresponding amide and returning them to an oximation reaction. Hydrolysis is at pH 0-4, pref. by means of an acid cation exchanger, at 50-150 deg. C,
