Disclosed is a method for preparing amides from aliphatic and/or alicyclic ketones as raw materials by heterogeneous oximation and rearrangement, which comprises steps of catalytically reacting ketones, hydrogen peroxide and ammonia in the presence of a inert solvent to obtain a solution of ketoxime, carrying out Beckmann rearrangement of the resultant in oily phase by use of oleum, hydrolyzing and neutralizing the product to obtain the desired amides. |
