Method for producing ε-caprolactam |
abstract |
A manufacturing method of ε-caprolactam, which comprises cyclohexanone oxime in a gas phase in the presence of a zeolite catalyst containing a silicon element and at least one element selected from the group consisting of alkaline earth metal elements and magnesium elements. A step of performing a Beckmann rearrangement reaction, wherein the concentration of the element in the zeolite catalyst is 3 mass ppm or more and 10,000 mass ppm or less. |
