| titleOfInvention | Method for producing amide compound |
| abstract | (57) Abstract: An N, N-disubstituted amide compound is separated from a reaction mixture after a Beckmann rearrangement reaction of an oxime compound by a catalyst containing an acidic component and an N, N-disubstituted amide compound, and the oxime compound is separated and circulated for rearrangement. When performing the reaction, the target amide compound is obtained in high yield by controlling the concentration of the by-product ketone compound in the reaction phase. An acid component derived from at least a strong acid anhydride, For example, sulfonic acid derived from sulfonic anhydride and N, In a method for producing an amide compound by subjecting an oxime compound to a rearrangement reaction in a liquid phase in the presence of a catalyst containing an N-disubstituted amide compound, N, which is separated by distillation from a reaction product mixture, Production of an amide compound by circulating an N-disubstituted amide compound in a liquid phase of a rearrangement reaction and maintaining a ratio (molar ratio) between the ketone compound and the acidic component in the liquid phase of the rearrangement reaction as follows: Method. [Ketone compound] / [acid content (in terms of strong acid anhydride)] ≦ 5 |
