| titleOfInvention | Preparation of lactams and carboxylic acid amides by Beckman rearrangement of oximes in the presence of Nb catalyst |
| abstract | The present invention preferably provides a lactam (eg ε-caprolactam, ω-lauro by gas phase but also in the liquid phase, by Beckman rearrangement of the corresponding oxime in the presence of an Nb-impregnated catalyst such as Nb on SiO 2 . Lactam) or carboxylic acid amides (eg, acetaminophenol and benzanilide). The reaction in the gas phase can be carried out at a temperature of 200 ° C. to 500 ° C. and a pressure of 0.01 bar to 10 bar in various reactors, for example fixed bed reactors, plate reactors, fluidized bed reactors, fluidized bed reactors continuously regenerated in a second fluidized bed. Can be. In the liquid phase, the reaction can be carried out in different reactors, for example autoclaves, stirred reactors, loop reactors, trickle bed reactors, at temperatures of 20 ° C. to 200 ° C. and pressures of 0.5 to 20 bar. The invention further relates to a process for the regeneration of said Nb-containing catalyst at 200 ° C. to 600 ° C. in oxidizing and non-oxidizing media. |
