However,it is rather expensive and difficult to prepare TS-1,which restricts the industrial production of caprolactam and needs further improvement. Focusing on this issue,this paper reviews the preparation of TS-1,including modified TS-1,TS-1 with large particle diameter, TS-1 compounds,the shaping of TS-1,as well as other technology related to the p...
