PRODUCTION METHOD AND BECKMANN REARRANGEMENT CATALYST FOR PRODUCING A CYCLIC LACTAM COMPOUND

摘要

Process for producing lactam compounds and Beckmann rearrangement catalysts There is provided a catalyst which is highly active, stable and safe and forms less byproducts for a process for producing a lactam, and a production process. A cycloalkylidene-aminoaxy-1,3,5-triazine compound is provided as a Beckmann rearrangement catalyst and/or a reaction starting material in a reaction process for producing a lactam compound.
