    • The present invention provides a method for preparing amides, in which an amino acid ionic liquid is used as both a reaction medium and a catalyst to catalyze Beckman rearrangement of a ketoxime, so as to produce an amide. In the method, the rearrangement is conducted by catalyzing a ketoxime with an amino acid ionic liquid having the asymmetric property at a moderate reaction temperature during a short reaction time, so as to produce an amide without adding other catalysts such as concentrate sulfuric acid. The method has advantages such as avoiding corrosion in equipments with pipelines, the high conversion rate of ketoximes and the high selectivity of amides.
    • 本发明提供了一种制备酰胺的方法,其中使用氨基酸离子液体作为反应介质和催化贝克曼重排酮肟的催化剂,以产生酰胺。 在该方法中,通过在短的反应时间内在适度的反应温度下用具有不对称性质的氨基酸离子液体催化酮肟进行重排,从而在不加入其它催化剂如浓硫酸的情况下生成酰胺。 该方法具有避免管道设备腐蚀,酮肟转化率高,酰胺选择性高等优点。
