日本住友化学公司正在工业化一条用环己酮肟生产己内酰胺的工艺。新工艺不会产生副产硫铵。该公司使用一种专用的高硅沸石催化剂替代硫酸，从而避免了产生副产品。新工艺在大约３５０℃和０．１MPa压力下在硫化床上进行气相贝克曼重排作用。以１∶１的质量比率混合甲醇和环己酮
Sumitomo Chemical Japan is industrializing a process for producing caprolactam with cyclohexanone oxime. The new process will not produce by-product ammonium sulfate. The company uses a dedicated high-silica zeolite catalyst instead of sulfuric acid, thereby avoiding the production of by-products. The new process performs vapor phase Beckmann rearrangement on a fluidized bed at about 350 ° C and a pressure of 0.1 MPa. Methanol and cyclohexanone were mixed at a mass ratio of 1: 1
