Abstract: 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.

Abstract: This invention provides a catalyst composition for preparing hydroxylamine, which comprises palladium, a platinum compound, a germanium compound and a carrier, wherein a halogen concentration of the composition is no more than 10 ppm. The catalyst composition is prevented from poisoning by halogens, and therefore the catalyst composition has high selectivity and catalytic activity. Further, the weight ratio of palladium and platinum in the catalyst composition ranges from 100:1 to 1000:1, such that the catalyst composition can be used to solve the commonly observed problem, i.e., decreased selectivity due to the excessive amount of platinum.
