Abstract:
The present invention provides a catalyst composition and a method for preparing an amide. The catalyst composition of the present invention including a hydroxylamine salt, sulfuric acid, and a nitrogen-containing heterocyclic compound is used for catalyzing a ketoxime to form an amide in the Beckman rearrangement reaction. The preparation of an amide by using the catalyst composition of the present invention has high conversion rate of a ketoxime, high selectivity of an amide and high tolerance to water.
