The present invention is directed to a process for preparing amides. In particular, the process is directed to a process performable on the industrial scale, in which a ketoxime can be converted to a cyclic or acyclic amide by means of a Beckmann rearrangement using 2,4, 6-trichloro-1, 3, 5-triazine as a catalyst in a nonpolar organic solvent.

La présente invention concerne un procédé de préparation d'amides. En particulier, l'invention concerne un procédé applicable à l'échelle industrielle, dans lequel une cétoxime peut être convertie en un amide cyclique ou acyclique au moyen d'un réarrangement de Beckmann faisant intervenir 2,4,6-dichloro-1,3,5-triazine comme catalyseur dans un solvant organique non polaire.
