Title:
METHOD OF PRODUCING AMIDE OR LACTAM
Document Type and Number:
Japanese Patent JP2012056846
Kind Code:
A
Abstract:
To provide a method of producing an amide or a lactam according to the Beckmann rearrangement of an oxime compound using a highly active catalyst system prepared by making use of inexpensive hydrogen chloride as a catalyst, capable of producing the same at a high conversion and a high yield without producing a large amount of byproducts such as ammonium sulfate.
The method of producing an amide or a lactam comprises causing an oxime compound to undergo a rearrangement using hydrogen chloride alone as a catalyst in a solvent selected from a cyclic ether and a nitrile compound to produce a corresponding amide or lactam. The amount of hydrogen chloride to be used, preferably is 0.01 to 50 mol% relative to the amount of oxime compound.
