摘　　要：环己酮氨肟化工艺是己内酰胺新技术发展的必然趋势之一,而钛硅分子筛TS-1的制备是环己酮氨肟化工艺的核心技术。但由于TS-1合成成本昂贵,合成条件苛刻,制备重复性差,制约了工业化的发展,仍需要不断的技术进步。本文针对这一主题,对环己酮氨肟化反应所需的TS-1催化剂的制备包括TS-1的改性、大颗粒TS-1的制备、复合TS-1的制备、TS-1的成型及其他的TS-1制备工艺等技术进行了系统综述。在环己酮氨肟化反应中,提高TS-1的催化活性、解决工业上TS-1的分离和回收难题、提高TS-1制备的稳定性和产量、降低成本等是未来TS-1研究的发展趋势。The ammoximation of cyclohexanone has become an inevitable trend of technological development of producing caprolactam,and the preparation of Titanium Silicalite-1（TS-1） has become the most important technology of the cyclohexanone ammoximation. 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 preparation of TS-1. The future development of the cyclohexanone ammoximation shall be aimed to improve the catalytic activity of TS-1,solve the recycling of TS-1 on an industrial scale,improve the stability and yield of TS-1,and reduce the costs.
