The invention relates to a process for the preparation of a ketoxime by reaction of an alkanone with ammonia and a peroxide under the influence of a catalyst on the basis of a transition metal, characterized in that the catalyst contains a metal-peroxo complex. The invention also relates to this process whereby after the preparation of a ketoxime the catalyst is removed and the ketoxime is recovered; the catalyst is oxidized under the influence of a hydroperoxide, after which the catalyst is removed and used again for the preparation of a ketoxime. |
