Abstract
The invention relates to a process of producing ketoximes, characterized in that a secondary alcohol, corresponding to the desired ketoxime, is partially oxidated in the liquid phase with O.sub.2, an oxidated mixture being thereby formed, which contains an excess of unreacted alcohol, the ketone corresponding to said alcohol, and H.sub.2 O.sub.2, and that said oxidated mixture is directly reacted with NH.sub.3 in the liquid phase (without isolating the alcohol, the ketone and H.sub.2 O.sub.2) in the presence of an ammoximation catalyst.
